Bitcoin Forum

Just come it to my mind. is it possible? to get hook into your wallet and send some to another wallet? :-\

You would have to define your question better in order to get a better answer. Technically, Bitcoin can't be currently hacked. However, what can happen (and usually happens) is that the hacker infiltrates your system by various means and then either waits for your password (if encrypted) or just sends them to another wallet. This isn't a problem that is caused by any 'Bitcoin flaws'.

It is possible for anybody to make up any private key. It is just very unlikely, so unlikely that it has never happened and most likely will never happen.

No it is not possible to hack bitcoins, or to use some technique so that withdraw bitcoin from someone account/wallet without any access to their account.
But if hack someones wallet. then you can transact bitcoins from their wallet to your own.

It is very possible to hack your bitcoin account many hacker try and practice to do it. No system is safe even though it has many security features it cam be crack. And also dont click on shorten links it maybe a phising site were if u log in ur id info and pass it well send to their number or email. Thats other way of being wallet is hackable.

No I don't think its that easy to hack bitcoins from wallet as bitcoin wallet are very safe having unique features and I think my bitcoins are very safe in my wallet.

Lols. I think this will not work this time. Those web developers will try to make their website and its information to be more secure and safe.
But there are still possibilities that hackers can access those websites.  since there is "NO SYSTEM IS SAFE".

Technically, no, bitcoin wallet can't be hacked. However, it is possible that your "system" where your bitcoin wallet is stored gets hacked, and that will give out the access to the hacker of your bitcoin wallet too.

So just make sure that your wallet is at safe place.

If you came from the future and brought a more advanced computer and knowledge you can hack bitcoin but for now NO!!

Sure, if you use an outdated and vulnerable system that is reachable from the internet. If so, its probably already part of a bot network and adding a key logger would be a simple task once its clear that you have a bitcoin wallet. The next time you enter your password, your coins would be gone. The keylogger is not even needed if you have a weak password.

Probably you can't hack a wallet (by brute force) with current technology because of Maths. However, you can use keylogger/malware to infect your victim's PC and can get their wallet private keys.

Ways on how to get the password of a user or of an account :

Dictionary Attacks
Bruteforce
Keylogger
Cookies of your websites and etc

So becareful of what your doing, Click at your own risk !

I don't know if you have seen but last months i have seen that many people were infected by a virus or malware which when people wanted to make a transaction the pasted address was always the hackers address so people were sending accidentally money to the hacker.

and there was another thread here about couple of people's bittrex account being hacked.
Make sure you enable 2FA on all trading sites which provide the facility

yes it is possible, most of time i hear that, i also change my wallet, you should refer XAPO wallet it is better.
otherwise you should wallet in your mobile . it is always better than other.

don't make me laugh dictionary attacks and brute force ,are you serious. it will take ages to get into, even with a super computer if you have a good password and everyone does use a strong pass for sure, the other two .keylogger ,malware and cookie hijacks are a reality and it is the easiest way to get into anyone's privacy  ;)

I have heard of the others, but what is this cookie hijack about?

I am still confused that you want to ask. If you ask that is it possible in the bitcoin wallet hacking..??. If that is indeed your question then I will answer if not please give a clearer question again because I do not understand.

Well its the first time i see someone talking about some malware virus that affects the adress where we wanna to send the bitcoins,besides those i believe currently there is no way to hack bitcoin,since the hash protects the network.

Youd be surprised how many set no password at all. I dont think everyone uses a strong password and some wallets are badly defended against brute force attacks as well.

I think that's not true, because if we use wallet stricken by malware (keylogger) surely they can easily into our wallets and take all the existing funds in the wallet. Because malware (keylogger) is widely used for something negative. For example my Blockhain wallet, once exposed to hack and they do backup all my Bitcoin addres to the wallet, but they haven't had time to take my Bitcoin.

Believe it or not, those malware exist, basically the malware will change the address whenever it detect that we are copying someone's address
When that happen the virus will alter your clipboard and change it to his address
That's why you need to always double check and make sure the address is right and not being altered by any mean ;)
I got this virus once and luckily I checked the address first ::)

That has nothing to do with what I just wrote. I am talking about wallet files and weak passwords. You talk about keyloggers (in which case the strength of the password does not matter).

btw if you are talking about blockchain.info, say so, there is no single "blockchain wallet", all bitcoin wallets use the blockchain.

Are you saying it is possible to make private key? i think you should have used impossible word in place of that possible word.
No it is not easy to just hack others bitcoin wallet, not even online wallet like blockchain.info

this is should become warn for we all who use online wallet and cold wallet,human error is can be happen in every security,even wallet have make best security,your wallet is not totally safe if you still not carefull. so far its really hard to hack direct to wallet account.

That is always possible, not is 100% sure. Don't kkep all your Bitcoins just in one wallet and make sure you have all security measures done. Some cold wallet is good solution

it is simply source routing IP packets, if you have'nt heard about it, no worries , internet is a place to study new things  :)


that is silly, if they are serious and have a good amount of BTC i am sure they will lock it up ,if not its simply a recipe for disaster . have't done any testing in a long time, so dont know about all the wallets . if anyone is serious about collecting BTC ,better have a good encryption and find a good wallet.

currently it is not possible to hack bitcoin unless someone got the details of it but nothing is unhackable so maybe it can be hacked in future because as technology is increasing more methods are coming out

When it comes to hacking, yes it is somehow possible only when the person gets your private key of the address you have stored your coins upon...
Else, it ain't easily possible as the system is too secure, except if your so-called wallet is on an exchange...

yes. it is possible if some one get access to your wallet's private key,. and may be the great hackers can hack some ones wallet who, althought wallets are very safe and their security system very power full.   

The argument is that its more likely to lose bitcoin because of a lost password than it is because of a hack. This might be true for some people, but those are usually also good a remembering passwords.

I have heard that one way that they can get your bitcoins from your wallet if you download a client with redirecting code that the deposits go to their wallet instead. So everything is cloaked but it shows as being received. Is this possible now?

Yes of course it is. If you have an easy to crack password you can kiss your coins goodbye, because sooner or later someone is going to steal them!

I really can't get it too. I know that a lot of people tryed to hack bitcoin but always it was poorly... I really want to know if possible way to hack bitcoin exist?

Correct. Like they say put it in many baskets. Blockchain got a good idea of password recovery where there are so many words that should be written before geeting back your account I think thatbis one good step for anti theft.

If you take any means of caution, noone is going to steal them, so don't mislead people into thinking it's something that's not avoidable.
If you don't trust your coins to be on an online computer, just make a paper wallet and keep it in a safe place.

I think he meant if is it possible to alter your bitcoin balance hacking your wallet software............

It's possible to hack anything the only questions are how difficult it is and how much time it would take to do it.  Make it too difficult or take too much time to be worth the effort and it most likely wont get hacked.  Best solution is to keep the bulk in cold storage off the internet.

No, you won't be able to do that because the ledger is decentralized... The data is distributed and hacking your own copy will make it invalid. This is the beauty of distributed, decentralized blockchain.

Thanks for the inputs, i think they cannot hack today but maybe in the feature there's a chance.
And were going to have another kind of latest digital currency. Maybe this is the circulation of hacking and digital currency world. Hmmm

If the question is: can someone get your btc if they hack into your wallet, the answer is yes. But that's the same thing than for a bank account you know?

Yeah, wallets can be hacked. It is the users responsibility to protect their login credentials and their keys. This can happen to anything online.  But as far as I know, the bitcoin system itself is still unhackable.

It is, but not likely. Bitcoin's programming is what really makes it such a strong medium.

Anything can be hacked, if not maintained according properly. You should follow the below mentioned two steps and you are safe.

Keep your Private Key Secure
Use Complex passord

If it is programming then another programmer can unlock it or get in it. Plus, there are many geniuses now that have very high skills regarding computers and many more stuffs. It wont be that hard for a person with a lot of knowledge regarding this.

if we talk about possibility to hack bitcoin wallet,its of course have any possibility to hack it,nothing perfect system in this world,but also its not easy to hack bitcoin wallet,so far i dont see any system failure that can break by hacker,i just hear bitcoin wallet hacked because human or user mistake,as you said user mistake come from they who not carefully click and open any link or phising trap.

Of course it possible, but the problem is it will take a long long long time. You would even dead before it finished

It has been happening for some years now. So yes, it's definitely possible. If your system gets infected, then the one operating the virus can basically tell your wallet/PC what to do and steal your coins by sending them to his own wallet. If you use a strong password for your wallet, then this will not happen to you.

it depends from the owner , if you can't keep your account safe maybe you can get hacked easily

very possible, I myself have experienced it. my wallet get hacked along with my first forum account too.
I do not know why it happened. but if you are more alert and do not install applications weird I thought would be safe

Yes it's possible.

Let's take an example about web wallets, some shitpeople makes phishing site and it's really present in some of the banners and ads today in some of the famous sites. It's actively seen too in some of the PTC ads today.

So if you really want to have your coins really secure, take it away from the crypto world if you know what I mean.

yes, in fact someone broke my pass on gmail, and i can assure you that it was a strong password with plenty of different characters and upper case etc, i'm lucky that i have the 2fa

so is definitely possible to brute force a password

this is true, as i don't remember the password of my first core wallet, tried recovering but of no use and i left that, this is the most common mistake ,people starting out in core wallet usually have these issues.

you said that hack bitcoin wallet is possible,tell me how its work and have you see some case that bitcoin wallet hacked directly by backdoor way?
and you said its take long time,its seems you have try and have knowledge about hack bitcoin wallet.

Bitcoin isn't hackable (ATM). These aren't hacks on Bitcoin, but rather hacks on particular users and their software (OS).

Such theft happens due to human error, most does.

It solely depends on the person itself as shorena said. I remember my 30+ character passwords just fine and have been doing so for years (my wallet is no exception).

There's a difference though. When your bank account is hacked you will get reimbursed for the amount removed.

yes this is your own mistake. We can call this as human mistakes. Sometimes the software can be hacked. But sure, it is impossible to hack your bitcoin from your wallet.

The problem isn't bitcoin, the big problem are the users, some of them not take care of its wallet passwords or don't use encryption. Using cold wallets no one will hack your bitcoins, but if you use a wallet on a computer infected and connected to internet, its possible to stole your bitcoins.

No it is not possible unless someone has access to your bitcoin wallet through your login they are unable to hack/steal any bitcoin from wallet. If it was possible then no one would you have to see here for adopting bitcoin.

I second that motion. Actually if the users are not careful of entering other websites or even hiding it somewhere else. It can easily hack by the other users. There's a lot of thing to do on how to hacked your accounts / wallet address. We should aware of that.

That hacker sees you got good background that is why he did it even if it takes too much time. Brute force takes like a day or two before gettig a password. That is a hell of a patience for that asshead hacker.

Most of the time, the only way you can get your Bitcoin hacked is if:

A. You occupy the same address too many times.
B. You have tied personal info with it.
C. You don't occupy some type of antivirus/malware/malicious adware software.

yeah, bitcoin can't be hacked as far as I know, but the thing is bitcoin can be stolen from your wallet, but if you secure your wallet with 2fa, saving your private key in safe place, your wallet will be safe I think.

We need some clarification here, what do you mean by it is impossible to hack bitcoins from a wallet,is it kept inside Fort Knox or what  ;D. if u can access your wallets from your computer and if your computer is infected ,yes you can loose your bitcoins from your wallet and we call that a hack   8)

I most often see people exposed to the virus malware that hackers can get your personal information and such seeprti email password
it happened to my friend. yobit their account successfully hacked along with his bitcoin

I think what he is saying is that it is nearly impossible to brute-force your way into someone's wallet and steal their funds, and it requires a computer to be infected with a virus before you can "easily" hack someone's wallet.

Its impossible to use brute force to hack your btc account or wallet because every wallet is secured by 2fa. The best way to hack wallet accounts is using phising sites and stole gmail password. By that you can enter on victims transaction. Wallet account and 2fa is can be bypass.

Bullshit.


Bullshit. How long a brute force attack needs to succeed depends on what you attack and the strength of the password.

False. This has no relevance.

No relevance.

Hacks and theft are very much real. Have you been living under a rock?

Exactly. Also waiting out two days is definitely not "hell of a patience". One could always use a website such as this one  (https://howsecureismypassword.net/)to test their password (keep in mind that you should use a similar one, don't enter the actual one). I'm at 869 Vigintillion years.

Someone could in theory generate/guess your personal private key, use it, and open your wallet from anywhere in the world. However, the chance of this happening is extremely rare, and is only theoretical. AFAIK, it has never been achieved before.

In order of your Bitcoins to be 'hacked' out of your account the perpetrator needs your unencrypted private keys. Now if you have a copy of them lying around on your HDD or you have a weak password to your online wallet theoretically your funds can be compromised. You can remedy this situation by strengthening your passwords by using a password manager and not holding a copy of your private keys or mnemonic string on your computer.

very possible. many cases in this forum when it used to be, some people wallet hacked.
some examples because, installing the application exe strange(usually wallet altcoins) and also there are some scammers commonly spread when used. but for now I think the forum is already tight.

there is a very simple solution to that which has been suggested many times already and that is using a proper Cold Storage.
practically you are cutting the connection between the hacker and your important information (private keys, passwords, ....) by keeping everything offline and away from any internet or network connections.

#you can't steal what you can't reach!

it is very possible there are some viruses that just scan computer for bitcoin and take it

therefore if you do not want your bitcoin stolen by someone then you are required to provide 2FA on your wallet dude.
so that they will not be able to get into your wallet. although they have the password
if you do not have 2fa the possibility to hack always there

I think the best solution and the greatest security you could have is migrating your stash to a cold wallet and setting up a smallish hot wallet for your daily spending. There was one guy that kept his private keys uploaded to his OneDrive cloud storage and allegedly the hacker had gained access to his email account and managed to empty out his wallet just because of one weak link that was his email password. I can't remember his name but I think he had a Bitcoin business or something like an exchange website. Anyway my point is that having strong and unique passwords is paramount and your email account is the key to your digital life. So if you don't want to use a cold wallet then at least get a password manager like LastPass or Dashlane and update all your passwords again.

Users do the same with bank accounts, and they have much more money in there to be stolen. But banks force people to use security measures, bitcoin has the freedom to use no security if you want.

How about the owner of the wallets.(wallet company) is it possible to check your balance your account details etc..
coz you sign up and create your passcode etc.. and put some bitcoins to your wallets.

1 more reason to get your bitcoins is they will get or  hack your passcode to your wallet so be careful about your passcode to your wallets.

There's a lot of reason to hack your bitcoin but there's a few reason to protect your bitcoins. hmm correct me if I'm wrong. ;)

If your computer safe from virus/malware/keylogger it's hard to steal your bitcoin from your wallet and a high proportion of malware is delivered via clickable links in spam which is crafted to look like it came from your bank, or wherever you trust  when you post your email address on web pages for a business then you are inviting spammers to harvest that address and then hammer it with junkmail.

Oh maybe you are a good hacker or a creator of that kind of application so you can make it fast.
That is my experience to the bruteforce that I got and it is an android application.
Maybe that app is the BULLSHIT! but not me.

Oh! and I am sorry I am not a hacker.

anybody here encounter hacked or your bitcoin gone?

all i know is that during the night the code was sent to my phone, so that is someone typing the correct pass

it seems that by typing my old hacked password(12 characters) here https://howsecureismypassword.net/, it say that it require only 485 thousand years, well it was not that strong after all,

no i never lost my bitcoin from my online wallet,i think coinbase is safe,and as long we applied all security,its safe and so far i got nothing problem.
maybe the only way hacker to hack bitcoin wallet is from phising by email related with bitcoin wallet..

Thanks for the inputs "rizkyhiw"

I think that would be a keylogger code. That is why I am also careful in some computer renting shops. You dont know what applications are hidden in that computer and rental shops like here in our place limits your access so it will really give you a hard time.

Good thing wallet sites have an email notification once your account is logged in. You just have to be fast enough to change the password.

That is one more help "Don't turn off the email notifications of your wallets".

I agree on "Don't turn off the email notifications of your wallets".

Doesn't matter if it's a good or bad hacker, it is bullshit. Brute-force methods are ineffective as soon as you pass a certain number of characters (usually very low) and use a combination of letters [A, z], numbers and symbols. It doesn't matter if you throw all the computers of the world are the problem, you will most likely not be able to crack it in a reasonable amount of time. Don't spread nonsense.

Step 1) Don't use web wallets in the first place.

Well only smart hackers did/do this and it had affected lots of people because it's hard to remember the address especially when you paste it directly when making transactions. That's why it is important to run your bitcoin client in a safe environment.

yeah if you use online wallet he only need your password and if you use offline wallet all he need is to hack your pc it is harder than password but there is very skilled hacker that will do the impossible to reach there goals.

Online or offline wallet are not that easy to hack as each and every wallet has its unique features which allows hackers to stay away from your hard earned coins.

Yeah agree with you. with email notifications you can know if there is something like a withdraw request that you do not do. so you can directly do cancel and change the password.
if you can you can add a notification to the cell.

Of course it is possible, and that is why all bitcoin wallets are permanently trying to improve their security measures, trying to minimize this risk. Of course we also need to take all the precautionary measures to avoid this contingency.

Email verification can be easily bypassed if the hacker have an access to your email and i'm sure those hacker get your wallet ID from your email,sms verification is really reccommended

I think using one bitcoin address or same bitcoin address for every bitcoin transactions will not make your bitcoin stolen. unless you do things like download at the links are not in the know. it may contain malware or you fill in the data and password in phishing site. where the password was the same as the password of wallet
it is often the case and make a lot of people lose their bitcoin because stolen

I don't think that is possible as I haven't experienced so far and I think bitcoins are very safe in any bitcoin wallet that we use as all wallets have some safe and unique features.

Yes desktop wallets are safe and cannot be hacked unless your desktop is hacked or stolen.
Web wallets have this fear that they can be hacked

The chances that your desktop gets hacked in comparison to a web wallet are much lower. You would have to either: 1) Attract attention somehow; 2) Do something dumb, e.g. click on suspicious link.

It is not possible to 'hack Bitcoin from your wallet'. This would imply that the Bitcoin software itself is flawed, which it isn't. Hacking the desktop that has Bitcoin on it, is something else (this is possible).

Exactly. There is no correlation with the number of times that you've used an address and the likelihood of getting hacked.

Online wallet quite vulnerable for being hack as some people may send you malware from clicking some link.
So just beware to not click any suspicious link that being sent from new guy that you just know it first time.

I have use multibit to import private key from online wallet if something happen to it

People only need to click on a certain link to get their computer infected. And in some cases they don't even notice that a virus has been installed on their computer.

That's a common way how people see their coins get stolen from their unprotected wallets. That's the hard reality nowadays.

Desktop wallet can be hacked too, did you know that
There has been many case of people clicking on some random links from the internet, and Bam
The hacker just infected your PC and probably a keylogger is installed there

So Desktop wallet has the same risks as you would have on your online accounts

I believe the truly safest wallet is Hardware wallet, they can't be installed with virus as keyloggers ;)
But hey, just my opinions

I think it can be hack to by using phising site were if you log in your user id and pass It will automatically save to phising site makers sites. some other phising sites is upgraded they make it look like online wallets to if you dont look carefully and you log in bang you are been hack. But to avoid it dont click thosr shorten links. Or so could lame promos bait dont cliCk For your safety.

Yes there some fellows are there they can hack our wallet. I had experience with this some one hacked my wallet and played gambling he loose all my money but not did anything other stuff to my account just used my balance that's it so be carefull about your wallet.

Every damn thing on the internet can be hacked. People just need time to figure how to

Propably hacking bitcoin would take biblic time...something to ponder about...

yeah every thing on the internet has the possibility to be hacked. but not many people can do that
therefore to avoid it. 2FA may be very helpful to secure your account

Desktop wallets can be hacked too, if you are dumb enough to keep your PC unprotected click everything which is in front of you.

Electrum is great , if you use it in safe environment  like Linux , keep its seed encrypted in safe USB or external HDD , don't click suspicious links (although risk of malware in Linux is smaller, it still exists).

If you are using a online wallet, first make sure to make your Gmail account 2FA with sms to your mobile phone, then proceed to create an online wallet, add 2FA there, and keep 2FA unique one time key which can disable it, safer in some encrypted document in USB or external HDD also.

This is the best protection you can have on online wallets and safety. If you are smart and brave enough no hacker can outbreak you.

I would like to suggest not downloading any shady pirated software because I have seen news where people got their coins stolen after downloading cracked games etc. The thieves can add scripts so that after running the exe.file you system will be scanned for any wallet.data files and your stash will be silently wiped away while you are messing around with the fake pirated  software. This is rampant with newly released highly anticipated games and such. Just be careful guys.

Technically not possible to hack a wallet unless you are careless with ur private keys and passwords

yes it is possible, but you have to be very stupid to let that happen, first of all, set as many passwords and other security a you can, don't share your codes to anyone because if you will, there might be a chance that somebody will try to get in your wallet, and if someone will then you will probably lose them

Your suggestion is not helpful. If one's desktop gets infected, no password in the world can help you. This is due to the fact that the 'evil' entity is able to install a keylogger and record your password(s). Users that use a desktop wallet need to educate themselves about general security and safe browsing habits.

I thinks there's no way out for the hacker. haha  ;D

There are so many ways of securing your BTC.
Getting a wallet like Electrum makes it so no one can send money out without a password.
Storing your wallet in cold storage makes it so it's not accessible from the internet (only by your computer).
People store wallets on USB keys that remain in a safe, but then you have the inconvenience of accessing your coins when in need.

It's really all about a security vs. convenience tradeoff, but overall some very solid ways of keeping your coins safe!

good idea:)

Did you mean to ask if it is possible to hack your wallet by knowing your wallet address? If that's so, then the answer is no.

Yes it is. If you download something infected by a malicious software, usually malicious altcoin wallets, it can make several things, from purely sending without your consent your bitcoins if you don't have any password on your PC, to copying his address instead of the one you want to send your coins to if your wallet is protected.

In our local wallets yes it is possible i dont know if it is inside job or what but many clients most especially big time investors had this problem. but in other wallet it is impossible to hacked because of their security features.

first of all I want to add that this is a very good way of securing your coins while still having access to them but you have to add one step and that is storing the seed in a separate place because USB disks like any other thing are subject to problems like breaking down or just an error like bad sector.

also for convenience you should have two wallets one is hotwallet for small transactions like the money you keep in your pocket.
and one is cold storage which has the big amount like your bank that you visit from time to time not everyday.

It depends per wallet. Blockchain.info runs in your browser, it is not possible for the 'company' to check your balance.

Indeed, I'm thinking the same thing a lot of people also think they are good defended against hackers but this is just not true because if you click on something it can go wrong in my eyes with all these virus links nowadays.
Its mostly just a matter of time before this happens and I think its also good to have a paper wallet for your big amounts to be sure you cannot not get hacked.

Yes it is possible if you have a virus already in the pc you are using which have a key logger in it and with that they can get all info on what wallet you are using and what is your password,its safe if you have a 2FA which will need a mobile phone authentication before you can withdraw your money.

Yeah thats true if your computer is not protect by any updated anti virus so beware in any website that you need to download or sometimes i experience force install from one website that has full of malware virus .. so if you are just holding more bitcoin in your desktop wallet make sure you have installed latest updated anti virus.. i can suggest to you to use kaspersky very active anti virus and very useful anti virus.. it can help also for most computer if your os is infected and it cant recover in any ordinary anti virus.. kaspersky is the only the best for me to recover and protect my computer of any virus online.. but kaspersky  license is expensive but you can find free trial license from online...

Also you are protected in keylogger software auto deleted by kaspersky...

You wallet can be hacked but it also depends on what kind if wallet you are using, if you use a blockchain wallet is easy for the hackers.
I would recommend you a paper wallet because they are secure and not hackable, another option is a hardware wallet that is also working very good to be honest.

 it possible to hack your bitcoin from your wallet?

yes! the hacker can get your Bitcoin from your wallet,
perhaps they can copy your key, so be very careful to getting away with it.
for them not to get rich at once. :-\

right, like a The DAO cases get attacked by a hacker and $60 million is stolen. a hacker can steal your bitcoin from some ways they can try. an old method using malware to stole your data,account,and password and for expert hacker exactly the DAO cases using code to infiltrate in your wallet.

I hope it is not possible to hack wallets.
But if it is what is the alternative?

You can hack other wallet , if the wallet not secured with hard complicated password (like symbol , numeric , and capslock)
Or some people use bruteforce method for do this , it takes more time but you can know the password at the same time.. 
And you can make malware password stolen to do this (Just kidding) ;D

no you can't, I do not know of the system used bitcoin wallet. but in my opinion if you do not have data on the wallet eg passowrd or private key it would be impossible to do such a thing. I think hackers do not break the wallet, but hack the data base of the wallet. Thank you

i think not easy but possible. no every one can hack my wallet. but the experts and the computer hacker can do this. i think such kind of technology are present and they are developing such kind of software that they can easy get access to anyone wallet. even they can reach to the banks treasures and we can see so many examples from our daily life. some time thy hack the whole websites of a particular department of a country.

Yes because we all know that there is no absolute security in the internet or cyberworld. But before a hacker could do that it would require many knowledge about bitcoin and how the transaction works.

It is also possible to hack it easily if the owner of that wallet is carelesss and don't secure his/her wallet carefully.

Just send to malware to their victims and infected the programs and malware can sending what the victims do with infected computers. and finally losing your account or amount on this account.

I think someone could hack into my account if you use the same password for every account. such as email, facebook, and others. of course hackers will easily fit into your wallet

Alternative are wallets with 0 hack histories so far , Electrum is one of them and is lightweight also. In the extreme case some random hacker can hack it , there is a nice developer with some helpers which I am sure they will fix it as soon as they can. Thats the alternative without spending any money, if you want the toughest and unbreakable defense for your bitcoins then it is very highly advisable you to buy a hardware wallet which are malware proof so far and they should continue to be as every thing happens inside their secure chip which is malware proof.

For now, none has able to hack a bitcoin wallet, unless if the hacker knows your passwords or private keys.😀

This is the main problem that often occurs in the hacking. most likely indeed the occurrence of hacking is because computers, mobile laptops, and they are exposed to malware and botnet. so if you don't want to get those problems, then don't ever do visit the site that untested and unexamined software download

Bitcoin itself cannot be hacked. The only methods of getting your funds would be for someone to get your private keys.

That's what people are doing right now. They're developing various methods to get your private key.

yeah especially if you're using an online wallet. of course they will request identifer very easily via email. and they can go in your purse very easily. therefore you must add security for your wallet

yeah if you're using an online wallet. and then they do not know your password. they will not be able to get into your wallet. the password can not be recovered by email. make sure you secure the private key and use different passwords for each account. I've tried it in blockchain and I was never in dikes

It's possible if the owner of the wallet is irresponsible on his/her account credentials, and its a matter of what wallet you are using.

anyways most of the wallet today have high security in logged in.

Its Not Possible My Account Never Hack Anyone Am I Right

Yes it is very possible to hack your bitcoin, even you have private key. Just make sure to do not show your private key to someone else or do not log in anywhere that is not trusted like computer shops

You need to run your Virus scanner Weekly or Daily if possible, to avoid virus and malware and get them out of your PC.
Use Linux it has the most invulnerable security in my opinion alternatively it is the most unexploited OS from hacker.

So my wallet has 2FA with a mobile. If that is the case how could somebody work out my private key?
Thanks

Yes it is very possible that your wallet Will be hack by someone. Now a days there's a lot of hackers so its better to secure your wallet ever now and then.  You can put a google authentication on in so that it can be easily to hack by someone..

You should listen to this guy advice, it is very possible that your bitcoin can be hacked from  your  wallet and move it somehwere.  I have  read someone unable to setup his 2fa security in his account in an exchange has been  hacked.   Losing all his bitcoin and altcoin.  So setting up 2fa is a must.  You  must be careful on clicking online links too, it might contain a malware that can hack your system and get your btc.

the answer is simpally no because bitcoin does not really is in your wallet it is just your private key is accessed by your wallet and you are managing the balance into that private key and if you do not even had access to the private key then there is no possible way to hack the bitcoin from the direct bitcoin network

If you have 2fa i think its hard to hack your wallet but if there is not 2fa they can be still bruteforcing your account to get your bitcoins or hack your account..  for hackers everything is possible.

In my opinion, yes! It is possible that someone will hack your btc wallet. So better to keep as safe as you can. Thats the possible way to do.

I know some cases that people have lost their Bitcoins from wallets because someone has the unauthorized access to it. Sometimes people are just not careful enough and they don't secure their wallets or they pick some malware. Anyway it is good to use multiple wallets.

I'm not aware of what kind of wallet are you using but if you use a wallet that has 2FA integrated then it's better.
So if the hacker has access to your pc then he can't transfer any amount because the code from 2FA is required.

to bad if his second method of verification is mail or if he receives his mobile messages also on his computer.
in general the answer depends on his definition of wallet and hack. but in most cases the answer is yes.

it is possible to hack anything as long as there is  human factor involved
the system itself can be as safe and tamper proof as possible,we all know how resistant sha256 is
BUT the owner of the wallet can be social engineered and his password stolen,he could print his private key out and carry it in his pocket only to lose it somewhere in a pub :),his computer may get compromised,he can have a simple pass which can be bruteforced in a matter of hours if not minutes etc.
blockchain technology in itself is as secure as it can be,humans are the weakest link here

Yes this is possible that bitcoin can be hacked from your wallet.
Be ensure that your password contains difficulty to hacked by
someone. Be careful on other website that you clicked on, that
might leads to pishing site that you often visits. And, I suggest that you used
2FA on your wallet for security purposes.

Of course it is possible IF you have a malware/trojan in your device and if that's the case then you CC details as well as PayPal would also be compromised, If your computer is secure and you are running a normal PC wallet then no is the answer, Bitcoins are not accessible remotely if your PC is secure.

For me it is not possible.  We have different bitcoin wallet addresses and it is not possible to just take bitcoins from our wallet just like that.  And I have read before that our bitcoin address was really hard to hack.  Maybe if you are a genious one with all the expertise and skills in coding and programming maybe it could be possible.  But I do not think that Satoshi did not think about bitcoin security.  I believe in him and I know that our bitcoin is unhackable.

I think Impossible but another people know your private key is possible happened

I agree, it can only be hack with the carelessness of the owner of bitcoin wallet. Even if he secure his wallet properly but his email on that wallet is not that secured his wallet can still be hacked. So we must secure also our emails not just bitcoin wallets to make it more harder to be hacked by someone. And also don't give info to anyone about it.

i think is impossible if you use strong security example 2FA
and don't say your password to everyone..

Any attacker having access to your system either through OS vulnerabilities, Phishing attempts for web wallets, malware that target Bitcoin wallets or altcoin wallets or Keyloggers can easily have access to your wallets. It's necessary that you isolate or cold store a large portion of your Bitcoins and only keep a small portion in a wallet that has internet access that you can afford to lose incase of uncertainty or theft.

yes i think it is possible and that is one of the most serious problem that we are facing in current days, as there are lot of experience in history.

sure i truly agree with u....you are on point..

I'm not sonsire what you are saying but I think I know. You can't hack into someones wallet unless it is s keylogger or something like that but that only get then they password. They need the ID too. That is the thing. I am not sure how someone can trick you into giving that to them. This is for online wallets. I think on the qt wallet the thief will need the wallet .dat file.

I think it might just happen when you use a purse that is not so safe and hacker had access to get into your email and I can be sure you will lose all of your bitcoin

Of course yes, if the owner of that wallet doesn't secure his account well like he doesn't secure the email associated in that wallet, his wallet can be hacked. The thief will just access both the email and wallet. Take all the bitcoin on that wallet and confirm it on the email.

Hacking your bitcoin from your wallet is very possible by using some methods but it will be hard for the hacker. He will either need a keylogger if it is an online wallet or a virus that can automatically auto copy paste the bitcoin address of the hacker whenever the owner copy paste a bitcoin address. It will be hard for the hacker to do it though since many bitcoin users are cautious against these methods.

there have been cases in the past that desktop wallets got hacked because of malwares or keyloggers. hackers can get access to what ever files on your computer including your passwords in some cases.

@OP yes it is possible so better be safe and use strong passwords

I don't think so that bitcoin can be hacked or hook into our bitcoin wallet is like generating a bitcoin wallet to hacked it? and then it's like a magical that there bitcoin wallet will be have some good balance. Try to protect your bitcoin wallet and you will be fine with that.

No Bro its Not Possible that Bitcoin Got Hacked By Anyon But It is Possible that  A Hacker Will hack the Wallet of Any Person And Then He Can Transact the Bitcoins available in the Wallet to Another Wallet........
So Am Last Its Possible to Hack a Bitcoin. wallet But I Doesn't Possible to hack Bitcoin.....

I think it might not happen if it does not come from your own mistakes, such as a virus hacker, hack your email or you exposed the trap of phishing sites. so long as you keep your wallet well, it will never get hacked.

actually you can't hack bitcoin or bitcoin wallet because of encryption which is very protective ( wether you arr using own wallet or another ) .
overall i mean all these depends upon the program script which allows only to send and Receive bitcoin from wallet but you can't hack bitcoin .

The biggest risk is always sitting in front of the computer.
Visiting sites that are not secure, talking too much about personal details, letting your password list lie open on your desk.
There are so many ways to give other people access to your wallet.
But I have never heared that there exists a program that can somehow get direct access to a wallet without the help of the owner.

A possibility is that the bitcoin client they are using was modified and was downloaded from an unofficial source and has the hacker’s addresses.

If you use same email and password combination in several website which you have used for your email account than anybody can access both your personal email account as well as all bitcoin web wallets associated with that email. Better to not use same email or email/pass combo in every site you register.

If you're asking if bitcoin can be hacked? No cause it's like hacking the internet itself, However hacking bitcoins from someones wallet is possible cause there is no safe wallet even if your wallet has a bunch of security features it can still be hacked tho it depends on the hackers skill. Most hacker targets the exchange sites so never keep lots of coins in them.

yeah my suggestion is to use a different password for each account, at least it will minimize a person get into your wallet. and do not forget to use 2FA I'm sure it will be safe

Yes, if the owner of the wallet is not very strict about the security and protection of his wallet, hackers may invade his wallet and withdraw all of your balance. There are already cases wherein their wallet has been hacked, especially those wallet that are very active and has email connected to their tweeter and facebook. So its better to make a separate email to be used of r you wallet alone.

yes i can hook into my wallet and i can send to other wallet address, i dont call it hacking because i own both the addresses  :P    8) since you mentioned hooking  ;D i would sweep the coins with just the private keys

Well, it depends actually...
You just might be able to get the password of the person's wallet by guessing. But otherwise, no, it's not possible to hack any wallets. And, also, bitcoin itself is definitely not hackable.

So, the answer is, Bitcoins definitely cannot be hacked and you can't hack any wallets without knowing the individual's password.

BTW, you could be a bit more specific in defining exactly what you want.  :)

probably not because bitcoin is secure with 2 keys that is one is private key and the other one is public key and I've can access his account only when both the key match each other. public is known but to find the matching public key it would take such a long time and even then success rate us very less

I would say, we can hack the wallet. Because why I am saying this is because once my friend experienced this thing. He just tried to log into his blockchain wallet. By searching it in google and went through the site but he just passed via the fake site like blockchain. Once he logged in. Thats it. He lost all his bitcoins nearly 0.08 btc are gone.

no its not possible or i can say if someone tried to havk then he needs a super computer nd it will take him around 3.5year to crack 1private key and i dont even kniw that if someone really done that then also will that address will have the balance or not :p

of course it is possible. even bitfinex which has a very strong defense could be hacked. I also lost some of the bitcoin from my wallet. at that moment I opened my wallet at the new cafe, when I opened my wallet, no transaction would occur, and it turns out, all bitcoin I have sent one of the addresses I do not know. Well, a lot of great hacker out there, so of course it is possible

Or maybe you can have bad luck and someone create an address that you use, I know the chances are so low however it's possible.
If you have big ammounts, just split in a lot of wallets, if possible, paper wallets and stay safe.

I dont believe its possible to hack wallets, otherwise the hackers would already had make it happen, some exchanges got hacked because they let a hole in the security, some were able to recover others wont be able anymore, hackers can clone pages to steal credentials and just.

I’m not expert in programming but still I think (based on my little experience) that hacking bitcoin network is near to impossible but one can easily hack device or wallet of someone and steal the bitcoin balance. Hacking bitcoin network is difficult but hacking online & offline wallets are comparatively easy task. There are many methods to steal bitcoins and thus we should take precautions in order to keep our bitcoins safe from hackers or any accidental transfer.

If in case, the hacker hacked your device then there is a chance of him/her diverting the funds to their own wallet. But here you cant fault the bitcoin, as any web device is vulnerable to hackers.

Well with bitcoin core, since its a full node you let people connect to you, so im not sure about that. I use a firewall tho, and several other anti malware, anti ransomware, anti exploit, and antivirus software, so any strange attempts to change my registry would show up.

Its not really possible if they do not know any details, for the most part its laying at yourself if you are giving away information there is a bigger chance you will get hacked.

Yes it is really possible, everything in internet can be hacked, but not all of wallet that hacked. Just divide your bitcoin in more than one wallet to reduce the risk. I tell you that it is really small chance to be hacked. So do not worry.

Not possible until and unless you get their private keys !

If you get their private keys, you own the wallet famn

I think i never heard any news regarding an account being hacked, so the security of bitcoin wallet is still solid, the one that being hacked usually it's from phising site and suspicious link
And hopefully it will never being able to be hacked so we don't have to worry about our account

No one can try to hack my account or my bitcoin wallet because my account are very secure. My wallet have authenticor when other people trying to open my account. My wallet have also bitcoin vault it is very secure because when you open my wallet you cannot open my vault because vault have other password.

As long as it is online there is a chance that it can be hacked. An offline wallet is still the very best idea for you can just pull your LAN or if you are using WIFI you could just turn it off. Even phones could be hacked just by its signal what more with a computer that is connected online.

I think there are many ways to break into someone's account even though you do not need a computer but you know the method so you can hack, there are many methods such as phishing, etc, all that is possible dude so beware

Beware of wifi network
Dont share your phone number to anyone
Buy vpn
Dont instal any fake file like guide free bitcoin

Thank yoy

I think is possible , but you can minimize the risk with use safe lock example 2FA

I dont think Bitcoin can be hacked. They are secure or no one would spend so much time spending to earn them. Well as for hackers they can hack anytime and they would be using encrypted methods, like maybe send you a false link and you enter your password then yes it could be gone. Otherwise you can be sure, it's safe. Just don't click faulty links.

Dont click any url ..beware of that

bitcoin wallet has a very strong security and reliable. when we can save the password well then we can ensure that we have the security of your account.

I think there is a possibility that bitcoin can be hacked by injecting malware to your system in search for wallet.dat.  there are cases in altcoin section where a newly launched altcoin have a malware injected in its wallet qt, anyone who run that said wallet have that malware triggered and a possibility of the bitcoins in their system being hacked.  So I think we should be careful in installing other cryptocurrency wallet in our system.

Bitcoin in itself has not been hacked, however there are a lot of ways for malicious persons out there to steal your bitcoins, for example wallets with malicious code, phishing sites, social engineering, getting your password through key loggers, etc

No such thing as hack has happened from what i have seen.But have seen few of my friends losing out bitcoins with hard disk crash/wallet loss

In that case backups are a must, if you are dealing with computer you must always have backups of all your important information since a hard drive can breakup any moment.

I do not think they can hack the bitcoin in private bitcoin wallet since they do not generate your bitcoin because if they try to generate more bitcoin account the system will gives unique bitcoin wallet address system did not give the address with already owned by someone.

Bitcoin wallet hacking is very possible , There is many way of bitcoin hacking , one of it is email hacking , Your online bitcoin wallet willbbe vulnerable if your email was hacked. Another way is by hacking your main bitcoin wallet account. But if you browse and dont show your large amount of bitcoin in your wallet no one will hack your wallet

Yeah, if a hacker has an access to your email then he will easily got into your bitcoin wallet and take it all away. Also if you post to social medias that you have this amount of bitcoin then hackers also will watch your wallet and find a way to hack it. We must properly secure both our email and wallet to make it difficult to hack by someone.

Bitcoin wallets are vulnerable to hacking unless it contains an impenetrable security system. The hacker need only to gain gain accessto your private cryptographer key or password and addressess. It target online services that stores the private keys and copy it.

bitcoin wallets can nit be hacked atleast not directly but there are some methods avalible without acctully cracking or breaching the security that is by spoofing the information maybe with a android rat or a small malware

Not just bitcoin wallets, all other digital properties are vulnerable to hacking by accessing our sensitive data. Weak passwords / keyboard logger / accesing bowser cashe for stored passed are few of hacking methods used to gain access to power emailor other accounts.

See, gaining access to a bitociner's mobile phone and his email accounts will make any bitociner get hacked if he is using online wallets. Similarly desktop wallets with same passwords.

In my experience, bitcoins can not be hacked from our wallets if we stay conscious.

Your wallet can be hacked. Bitcoin in the wallet can certainly not be hacked. When you lose your bitcoin then your wallet was been access by a theft and get your bitcoin but still  bitcoin in that wallet certainly wasn't able to be considered as being hacked.

Nope until you log in to the hackers site which is similar in look like your wallet site. Your amount you have in your wallet all will safe, if you logged in it automatically move to the hacker

Probably not possible to hack bitcoin to take away bitcoin from others wallet. Because it is secured by 2 keys and one can access the account only when both the keys namely public key and private key. And it's quit tough to find the exact private key.

as bitcoin is not a paper money that can be hacked, if some one is going to hack your bitcoin he will first hack your bitcoin address and that can be done by several methods, like using malware or hacking your email address then he can get access to your wallet and can steal your bitcoin, i think this issue should be solved on priority basis, as it is effecting the image of bitcoin.

yes it is possible as we have some live examples here in this form. as in previous days the hacking of bitfinex was really a big problem, as the whole the hacker bitfinex and take all the bitcoins from it .

no its not possible but there are very rare chances that any type of spoofing will work for the very very less carelessness of the user but for a normal user its really high security which hackers can not break through (easily) but yes any crezy hacker who spent 3-4year to hack one address they have some chances

It is possible if you work with negligence, that's your money and it's your responsibility to protect your money. And if you consider your money as investment for your future then the more you have to exert effort to protect it.

It is extremely possible if you have malware on your computer. Otherwise, if you are looking at decent security practices, the only attack vector can be the wallet software itself.

1. The wallet may generate insecure keys as a result of flawed RNG, either intentionally or unintentionally. Re-using the 'R' value in the generation of transactions can allow attackers to scan the blockchain for addresses that are insecure and it is extremely easy to crack the wallet to get to the key.

2. The wallet may be malicious and send the keys to a remote server and attackers can gain access to your keys there.

Otherwise, if quantum computing becomes a reality, the ECDSA may in theory, be flawed and can be cracked over time.

Yeah, someone who has financial or price would surely have thought of being able to protect their property from crime or theft that could have made them get a loss. So does bitcoin, if we want to have a bitcoin intact and does not have an accident theft then we should be able to protect your wallet, owned by a couple of security are very complicated. Be it a wallet that has large quantities or small, because all data must protect

If via remote desktop connection, then yes, it is possible to send some coins while you are connected to the said wallet and then send the coins from that address to the other address but that isn't hacking in any way. But if your question is about cracking the wallet remotely using only the pubkey of the wallet then no, it will take a longer time than that.

I really doubt they can hack, otherwise it would already happen, there are a lot interest over bitcoins, hackers are requesting their payment to be done with bitcoins, if they could acess wallets they would do those already. The only way to them get acess is to make like the last time a fake and similiar page of blockchain or other wallet provider, and some person which didnt pay attention put his details there.

Well if your PC or celphone are infected with some virus/malware, for sure they can hack your wallet.

Because some virus can see what you type, can take printscreens and things like that, so you have to keep your pc clean.

One good alternative is using paper wallets ;)

may be if someone know your private key , so be carefull to say about your key

Bitcoin can't be hacked however you will enter in the site and login to a fishing bitcoin website or you download the application that has virus and you login to your wallet it can be hack your wallet they will known your password and send your money to their wallet.

Yes, it is really possible, and lost 0,08BTC that way, only 16$ at that time, but much more now. However, since I placed a password to my wallet (yeah, was pretty stupid to don't put one : I thought I'd have to enter it each time I would get into my wallet :P), never had any problem ;) !

With enough computer power it is possible to hack... But "enough" is a lot!

That is not a big amount of money, but is never fun to get hacked and lost your money. If someone has access to your PC or your smartphone with a virus or malware, for sure he can access and transfer the fund to another bitcoin adresse.

Always a good idea to implement the basic security into your wallet ;)

Possibility is possible as long as you're connected to internet many hackers will posibly hack your wallet because money is always involved. Best thing to do is to installed strong security on your pc or mobile phones and seek good advice from experts for your safety. Most importantly do not share to anyone your wallet password because it is the most reason for your account to become unsecured.

I think the best thing you can do is to actually have a new PC and ONLY use it for Bitcoin transactions. You can find one even at $100-$200, you don't need a super fast one but a simple, small and portable netbook that can run a browser on it. I'm using such a laptop for my main wallet and for the other wallets which got <$5 in them I'm using my phone or main computer.

It is indeed possible and in some ways is already done.
There's softer methods (like producing viruses). These retrieve data directly and mean that less computation power is needed by the hacker (an example being the AV coin project that launched from this site a while back).
There is then the "brute force" approach, which doesn't work as well with Bitcoin (as there's so many posibilities) and takes lots of time and computation due to the difficulty.

Yeah, bitcoin wallets can easily be hacked by the fault of the owner of that bitcoin wallet. He didn't secured well his wallet which makes it easy for hackers to login in his wallet and steal his bitcoin. If you secure well your bitcoin wallet and also your email, hackers won't easily steal your bitcoins.

That is not the fault of the wallet, it is a users fault that your bitcoin was stolen. It is good that you learned your lesson. I hope you used a complex password to protect your wallet now.

definitely yes, it is possible to hack your wallet and took away your bitcoin if you have been attacked by a phisher/phishing sites therefore some services including blockchain is advising us to secure our wallet with a passphrase and two factor authentication in order to be safe from the hackers because with 2FA it is very impossible for unknown person to access your wallet.

Yeah, I trust 2FA in my online wallet, so far my bitcoins are intact. I guess it only depends on the negligence of the users as there are software who will try to steal your money, beware of those and if possible do not expose your computer too much by installing unknown applications.

Due to the continued updation along with technology development hacking is highly impossible. But I have heard of very few hacks which caused due to the careless of users. Most wallets were highly secure with varying security features.

That is why it is better to store your bitcoin in an offline or hardware wallet. No one can hack your wallet if it is offline. But ifyou have to use online wallet, be sure to secure your credentials and your devices so no one can take your coins away.

I don't understand the question fully. Hacking a wallet is sort of possible if someone has an easy password. What is meant by hacking btc? Ruining the code of bitcoin? That sounds sort of possible but I would call it spoiling bitcoin, not hacking it. I surfed the Internet and found out that by hacking people usually mean stealing. And yes, it is indeed possible.

phishing will only give identifer and password and I think the phishing attack will be useless when you have such sms authentication verification or 2FA, because they will not be able to pass it, so use 2FA to avoid hacking

Yes, it is possible. Nowadays, hackers use SQL injection to hack a bitcoin wallet. So how does it works?.
In order to do this, they'll send an amount into a victim's wallet. Afterwards, they would do the SQL injection that will took 7 minutes in total. After that, the amoun that they send on victim's wallet would be multiply by 2 or 10. Be careful of dropping your wallet pubplicly, and do not put all your money in only one wallet.

this is could happened if other person know your key , so be carefully
don't say your key to all people

everything is possible i think can if you not be carefully with your private key

Hacking particular Wallet is possible, though every wallet service providers had enabled high security features. For increaesd and improved security these days lot prefer offline wallets. I haven't come across any wallet hacking but highly secure banking networks have been hacked, which describes the skills of hackers will work more than the developers.

I think such type of hacking that is mentioned by you that " by your own wallet to hack another " .
In my opinion it is not so simple wether you want to hack own wallet or of another because the securities in the Bitcoin wallet in the current time very power .
Since if you can get private key of any btc address ( wether address is your or not ) you use it for deal without any problem .

It is possible. But it takes more time and effort to hack someone's trasanctions or bitcoin wallet than just mining itself. This was discussed in Satoshi's whitepaper. He was saying that if a hacker would try to hack the blockchain, the resources required will be more expensive than just trying to mine it the legit way. So to answer this, yes it is possible but it will not be worth it.

Pretty much anything is hackable, as long as there is intent to do it. However we may be diligent and vigilant with our security settings, sometimes the best hackers can still break that barrier / protective wall. It's part of the risk of doing things online and as long as something has value, I think it will always be subject to threats and hacking.

you have to learn what are the ways that you can get hacked and then try to find ways to prevent those ways. for example one of the most common ways of getting hacked is having a key logger on your computer. solution is simply having a good anti virus and not downloading things you are not sure about.

and as for bitcoin and bitcoin wallet as long as there is cold storage everyone should build themselves one and transfer their bitcoins there to prevent all kinds of hacks.

Having a good anti virus is just really a basic requirement if you like to have a secure and clean pc or laptop. Stealing would be impossible especially if you know about your computer and no one could able to put keyloggers unless if you downloaded some files.Thats why we should be vigilant regarding into these because being hacked is possible within this kind of methods by hackers.

I think people will not be hacking the private key. you have to be careful with the spam in your email it might be a phishing or the like, use authentication so that they can not enter. although getting your password

hacking private key and losing it are two different things. private keys on their own are string enough that it makes hacking them impossible if that is what you were thinking.
and so far whoever had lost bitcoin or their private keys were because they have lost them. like using an unsafe computer which has keylogger on it or entering their private keys on a website which they don't know.

Yes hacking wallet or exchange is not a difficult task in some cases but hacking the bitcoin network is near to impossible (it will need hell of mining power share) thus we are vulnerable mostly on our individual level (by phishing, social engineering etc) and then on community level by losing all the funds due to exchange hack. We can only take prevention on individual level and rest of the methods are out of our control as a bitcoin user.

I am absolutely sure that nobody can steal bitcoins from my wallet (assuming no web wallets). But I'm not sure that I will not forget my password or my passphrase which maybe I cannot remember. I am much more confident about the money in bitcoin despite of the money in any bank

I think is possible but it is very difficult when I log into my wallet need to be authorized in my email and after that will be sent code 2FA for my number phone, I think so difficult to hack this wallet.

the security of bitcoins is  becoming tighter day by day .so  u can see some flaws in accounts  .but u cant expect accounts to be hacked  every now and then well if u dont have any enemity with the hackers otherwise it will be fine to keep  a lot of bitcoins in ur account.

having a good anti-virus isn't enough if you are not responsibly and carefully using your pc/laptop or any device and you tend to download unknown files from unknown and Untrusted websites then you are still on the risk. anti-viruses are not the same they are not actually the same when it comes to that certain feature where they will give you a notice when you are downloading a file that might be unsafe. we should beware on downloading files from the internet as we wouldn't know if it is safe or it will bring a harm to our computer system and will be access some of our accounts.

can , so don't save all your bitcoin in one wallet and be carefully

Well I suggest you choose the wallet that is very secured. And avoid sharing your earnings online to prevent other from thinking to hack your account. I think it is very safe to keep your bitcoins from your desktop wallet rather than online to lessen the risk of hacking your bitcoin.

Yup todays verifications before logging in or accessing for transactions seems really impossible to hack. But to lessen still the worry I prefer saving / storing  it in different wallets just for assurance because it still hard when I put all in one wallet so atleast even one may hack i dont lose alot though my money is not that big but still I worked for it and its important by just storing it for sure soon it will doubled the value.

I doubt a hacker will try that approach, what I think is most likely is a virus or trojan infect your computer and then the hacker gets your passwords including the ones for your wallet and then the hacker access your wallet and leaves it empty, I think that is more likely.

it is possible, yes. just like the past hacker who hacked an exchange (if I am not mistaken). but it needs high level of hacking competence, of course. you need skill to be able to hack bitcoin which is known as unhackable system.

Yes, anything on the internet can be hacked. Especially bitcoin which is also a currency makes hackers monitor your wallet and try to hack it. If they know you have some big amounts on your wallet they will use any way of hacking they know to steal your bitcoin from your wallet.

Yes, it is possible, honestly it did happen years ago where bitcoin worth of 1 million USD have been stolen to the blockchain and it is possible to happen again. There is no impossible to those black hat hackers that only knows how to steal something from someone's property. We just have to be prepare for this, so we are not gonna surprise in the future. It would be better if we would convert all the bitcoin that we have in the right time in fiat so that we won't regret a thing even this hacking bitcoin season comes.

Bitcoin isn't possible to be hacked your wallet is, especially if you are storing you bitcoins using a web wallet so you need to secure your account and you should be aware of those malicious softwares and phishing sites also you should choose the best web wallet that is not vulnerable and cannot be easily hacked.

The fact that bitcoin address are constantly changing makes it impossible for anyone to track down your wallet, why do you think governments don't wanna use it as an international currency , and why do you think hackers and drug dealers use it on the black market thats because no one knows where the bitcoin goes to.

Formally, Bitcoin can be broken, but this is unlikely, because the transaction in the virtual currency Bitcoin does not require the disclosure of personal data, as a system of two keys: a public key and private. The first (outdoor) is open to anyone who knows the address number of your purse, the second (personal) - is known only to you.

Except for keyloggers and other spywares, Bitcoin hacking is impossible for now (or nobody found a way to do it yet). If you do not have the wallet ID and password(s), unfortunately that amount is lost forever. Do you remember the e-mail you used for creating that wallet? Or just any other detail? If it was a cold wallet, it's impossible. If it was a web-browser based one, there are ways you can get your money back by contacting the specific company and proving that it's you.

That how revolutionary the internet now, there are a lot of security features that we can used and now it's up to us if we are not careful with our information. Tips were found in the internet on how to protect our bitcoins so we have to follow that and take care of our investment.

Yeah it definitely is possible for you Bitcoin wallet to get hacked, but the chances of it actually happening is very low. It is definitely something you shouldn't be worrying about. That is unless you use a online wallet. Then it quite possible that you could get hacked, but most people that use an online wallet only keep a small amount of Bitcoin in it. If you are using a hardware or software wallet, then you are pretty safe unless you download key-loggers or viruses.

Hackers can also use phishing and fake the website of a wallet, then you download the infected wallet and when you add bitcoins to the wallet and then you make a transaction your bitcoin will be sent to the address of the hacker.

If you use a really simple password yes.  Google "entropy" and it will explain this to you.

It really depends on the security of your wallet, becayse I assure you that Bitcoin won't just nagically disappear in your wallet. However your password in your wallet can be retrieved by anyone if it is easy, because anyone can reset your wallet if they all know your security questions. Also I recommend wallets that send you text messages with codes on it in order for you to access your wallet from other devices.

Ofcourse its possible. Sometimes when installing bitcoin wallet, some wallet are infused with virus which takes all the details including passwords. Make sure  you have strong antivirus installed in your computer if you dont want to lose your bitcoins. Dont put any  untrusted application in your computer and make sure to format it regularly.

The far more likely scenario is that someone gets some kind of malware or keylogger on their system,
and an attacker is able to get the private key that way.
Even the NSA or some other state sponsored agency would have trouble cracking a bitcoin wallet at this point.
They would put that computing power to something much more profitable than trying to steal someones BTC.

Yes ofcourse. Its really possible. One of the common thing that usually happen when the virus infected your computer and goes through your wallet and takes all the details including passwords and your private keys. Many victims are experience this kind of thing. Also phishing. Phishing is when you enter your passwords into untrusted site of applications. Through this, they can easily break your security. It is know as keylogger. If you have computer with strong antivirus, you should be fine.

Antivirus are not a guarantee since they give false positives and programs that are infected sometimes go undetected, so instead I will suggest to use a more robust operative system.

yes, of course it's possible. even bitfinex which has excellent defense can hack, especially if only a wallet that defended only by password. Well, even though you have given super tight defense, I think it can still be hacked. I say that because I feel that the hacker has no restrictions on the internet. you just need to remember that the internet is no safe

We all don't know if Bitfinex hack is really authenticate and true. It's easy for some exchanges to say that their security got breached. It is mostly the reason of some exchanges that turned into a fraud one. No proof at all since stats can be modify to show all their users that some irregularity happen to the exchange.

Hacking is possible in any kinds of things especially online. There are even persons who has some super tight security from their belongings but still experiencing theft.

Those people that got hacked are most likely rich person. Hackers are very attracted to their bitcoin or bank accounts which they will find any possible ways to hack in your account. And hackers are more difficult to be arrested by authorities because they move in the internet and we can't say who it is.

I agree with you . no one is safe as long as we keep the data on the internet. when they (hackers) can take the database of a website then at that moment we could lose what we have. nothing is very safe when we go online !!!

Well, if someone hacked your wallet? that does mean that bitcoin was hacked? of course not. If someone was able to steal your bitcoin from that address that does mean that bitcoin was hacked? of course, it isn't. It is just pretty clear that bitcoin cannot be hacked but only those other application being used to support bitcoin

Bitcoin wallets is prone of hacking ofcourse its an online stuff what can you expect.But you can prevent it by putting 2Factor log in in your wallets and stay away from clickbaits around the internet

You can do that but you can also simply just use a offline wallet what is also working great in my experience.

Everything can be hacked with the right knowledge and enough time, probably one of the best defenses is to not become a target, if you have lots of coins then don't keep them all in the same wallet or address, unfortunately for big businesses like exchanges not becoming a target is impossible.

Everything except a good hardware wallet in the case we are talking. I know lot of people will raise doubts that the hardware wallet is not secure enough but for me they are wrong by a big margin. This is the most perfect way to keep your coins as hardware wallet are malware proof unless you do thousand transactions in an infected PC. In a Linux PC hardware wallets are the best choice. I keep all my coins in my hardware wallet and nothing have happened to me nor it will (101% sure of this).

As for exchanges with good security measures they can protect themselves against hacking. 99.99% all the major exchange that claimed they got hacked for me it was an inside job.

Yes it is possible through your bitcoin wallet .well then the the person is a pro hacker and have a lot of knowledge in computers and very few people does that .and people with too many bitcoins have that risk .

You are correct on that, but even if the hardware is tamper proof, the weak link will always be the end user, if the end user is careless about the usage of such a device there is the possibility that some hacker will find a way to separate him from his coins.

That is pretty possible. Especially when you use public Wi-Fi when you work with your online wallet. That's the same dangerous as to use your e-banking on public Wi-Fi - your passwords can be stolen. So, never use public Wi-Fi, that's the first thing you have to know. And there is not only online bitcoin wallets. There is USB wallets, they are much more protected. So if you scare too much - buy USB wallet.

I think it would be hard to hack a bitcoin wallet,
because some wallets to use good security

I assume you mean hack into another persons wallet and send it to yours ? That's a really strange question to be asking. No you can't hack someones wallet , it doesnt work like that. You dont hack someone directly you will need to try find a way to get their private key or passwords or F2A verification or some other means.

I don't think he meant that, what I understand on the topic is that is there a possibility that one person can hack into our wallet and change all the information to steal our account or just simply steal our bitcoins.

If there are hackers who can hack ban accounts , youtube accounts etc etc , then surely there might be hackers who might hack bitcoin wallets and steal cash.

That's true... Who knows, someone has already planted their malware in your computer and gathering data from your disk and tracking all your activity in the internet... Carelessness isn't the wallets fault, so we should take care of our wallet since it is our money and therefore taking care of it should be our responsibility...  :)

That's true, anything can happen through online network that hackers actually can steal your account information.
Just to be sure didn't make any mistakes such as download, phishing, etc and make your own backup plan such as store your bitcoin into offline wallet or another offline pc would be good.

If you could brute force your own password and successfully find it, then yes you can hack your own bitcoins.

I am also using WiFi but not facing any type of problem regarding safety of Bitcoins wallet. But yes I am somewhat agree with you it can be dangerous sometime. Now all bitcoins wallets are using best verification and security service that is very difficult to be hack so I think our money is safe.

If you want to be sure, install the wallet first in your PC right after you have formatted it. Then add a strong and complex password like 32-65 characters which contains no dictionary words but only something that has meaning for you only, special characters help a lot too.

By doing like this you suddenly are way too far ahead of the game for any hacker. Just keep your PC protected though and never use web wallets or wallets that you have to access from some third parties like blockchain.info, xapo,coinbase etc.

although the security of online wallets are satisfactory but still there are always chance of hacking your online wallet and one can get the bitcoin from your wallet, therefore try use different wallets for your bitcoin, if you have a good amount of bitcoins.

Is this a question?? Or you want tricks and hacking techniques?? Well watever.. i will advise to use wallet with 2fa security enabled and apply it on every activity even open also. Its a safe way to stop hack into your wallet.

i think its impossible to hack bitcoin from any wallet because there is bitcoin wallet which is going to more secure and people keep their bitcoin in their wallet with out any worry so we feel safe and secure in any secure wallet and i think that bitcoin wallet is much more safe than bank wallet.

Hacking bitcoin network is near to impossible and this is applicable universally. On the other hand the possibility of hacking user’s wallet through user’s device differs from person to person because not most of the users are security conscious when it comes to their wallet. It’s always better to take precaution rather than cure. It’s never too late to pay attention for security measures while holding bitcoins.

all wallets still vulnrable to hack, online or offline, as with offline can be your friend borrow your laptop and open your wallet then take your bitcoin, the safest course is to add 2FA. it will provide better security wallet

Says it all :)

Nothing impossible, I sure that any chance to hack our bitcoin. Now everyone saya that bitcoin is perfect from hacked, it also happen with emails, Bank acount and more, now that is often happen.

It is possible for one to loose one's bitcoin to a hacker if one does not take necessary security measures to secure his/her bitcoin loggin information

for now it is very difficult to hack somebody wallet, the protection level of bitcoin is very high, most of the time the people got hacked because they were careless, maybe they install hidden malware, or input identity in a phishing sites or recklessly input password in public place, from the system it is almost impossible to hack for now

It is possible for one to loose his/her bitcoin to a hacker if one does not take the necessary precaution to safeguard one's loggin information.

Yeah it's mostly because the wallet owners don't pay attention to the security system like they only have one-step security or they forget to log out their wallets. Sometimes it's just because they are unluckily chosen by the hackers to be the next target of stealing bitcoin, or maybe other unsual cases like there was one time when a bitcoin user of this topic accidentally generated a wallet which already has a huge amount of bitcoin.

It is possible to get your bitcoin wallet hacked if you don't take good care of your private key. You can't have the option of being carless with your passwors/private key. Make sure keep it some where safe and try to enable 2FA if you're using wallets such as blockchain.info

It will happen at users fault, it's our responsibility to take care of our private information to access our account, without it our bitcoins are gone and since it is not bank where there is insurance we cannot recover it.

if you are not very careful and not watching your activities you could possibly become a victim of malware, phishing sites but still you can prevent these you just need to avoid downloading/installing a software from untrusted source and do not easily input your online credentials to various sites sometimes many phishing can be noticeable through the address bar . and yes you are right, we should avoid putting our credentials in to the public computers .

Yes, why not? The possibility is endless and your account can be hacked by some hacker who will send money to his own wallet. However, there are some precaution you can take to minimize the chance of getting hacked. Like 2FA authentication or email authentication. Where you will recieve sms or email with a security link, through which you can only access the account.

But it is always wiser to use a hardware wallet for majority of your bitcoin. Also maintain a coinbase or blockchain wallet to receive funds from outside. Do not disclose your main wallet's id anywhere. These ways will make you safe from hackers.

Almost all web wallets have a 2FA which can provide a lot of safety when it comes to potential hacks ,for me the best wallet is Xapo , it has a very strong security , it has a password and a PIN code and a SMS verification in case your wallets gets logged on from another IP, so the chances of your getting hacked is very small.

Sorry for off-topic, but what is a good keylogger? Is this one https://www.refog.com/ (https://www.refog.com/) good enough to be installed on Windows? Thanks.

Yeah absolutely right , xapo is have good security but i think not only xapo that have few layer of security , i used blockchain app on my smartphone and there is a password and pin code  while open the wallet. And it is also have safe security i think.

Basically all wallet equipped security features, but surely there is available way to pass through. Never mind the web wallet, if we have wallet from offline also could still be hack. My advice is, often to replace setting password, email address, mobile phone number and also don't often open wallet in indiscriminate internet access such as wifi.

xapo wallet is very similar with the local wallet provider that we have here in my country, they are same when it comes to the security . you are able to make a 4 digit pass code if you're using their mobile wallet service and also they have SMS verification every time you logged in your account to a different device and IP . but the problem is that they also have an option to authenticate the log in attempt which is the email-authentication and you are possible to be hacked if a hacker knows even your email address .

It is not an issue we should worry if indeed we have account confidential and not to use access in vain, for if we cannot protect the computer then all things are very secret can be taken over by hackers. The secret account I mean is an account which indeed you never spread to was introduced by friends or anyone. So, indeed it is also one of the ways to avoid hackers and other than that we should be able to keep your PC/Laptop/hp with no clicks or visiting sites that have not believed
 

Third party wallet can be easily hacked and it is not secure at all since you let someone else hold your Bitcoin. If your computer is infected by ransomware or virus, they can easily access your account.

Computer viruses are known factor of being hacking. But don't forget about public internet. That is not less dangerous than viruses. I never use my wallets or operations with them when I'm sitting in some cafe. I even don't comment there, to hackers don't steal my wallets number.

in fact all the online wallet have good security and all are using double or triple layer of security but still there are peole who can easily cross thes level and can reach to your wallet easily, therefore it is more important to have your own wallet security

Many bitcoin wallets including some wallet providers suffered from hackers that took away millions of bitcoins from them. Some of them are Blockchain.info and Bitfinex. Some of the hackers uses phising sites and phone numbers to hack wallets according to a report.

even if we kept our online credentials confidentially there are still ways for other people to get it and of course it is indeed you should never share it to some of your friends or to any other people . aside from avoiding those untrusted sites you should also keep your computer in private I mean you must have a separate account for administrator and for guests which is for public in order to avoid them from accessing your accounts .

IN this open world everything can be hacked so hackers hack the only wallet and transfer the bitcoins to their wallets this only happens, there are several accounts that have been hacked and no one knows.
so hacking is the big issue in the bank , and many people got their bank accounts or wallets get empty.

No it is not possible to take someone else bitcoin from their wallet without password

I always check the few first and last digits or letters of an address before I send any bitcoin to it because it's almost impossible for the automated address generating system to generate addresses in matter of seconds that looks like your own address.
And  for the OP I must say that of course it's possible to hack your own wallet but who do you think will compensate the stolen funds?

The stolen funds can easily be laundered if one uses it, just by simply using it in gambling sites like sports betting then hedge on the other sites then everything is clean now.

if we have the password then it is very possible. the important thing is keeping us how the password is not known to others. create a strong password, then we will be safe wallet account.

I think i never heard any news regarding an account being hacked, so the security of bitcoin wallet is still solid, the one that being hacked usually it's from phising site and suspicious link
And hopefully it will never being able to be hacked so we don't have to worry about our account

I didnt hear some new too related to online wallets that is being bruteforced to hack and stole of the bitcoin inside it but the incidents of being robbed because of virus and phishing link then i would really believe because if someone would able to know the important informations regarding on your wallet then the risk of being robbed is high.

In the online wallets even its preview says its secure. It is possible also to hack your bitcoin wallets and the only developers of the wallet you stored bitcoin can open your account so now you know who could hack you. The cold wallets also has to be hack, although the developers could not do that but I don't know who.

In my wallet?I could say they would really have a hard time to hack my wallet its on either on web wallet or hardware wallet because I do set it up 2fa passwords and kept all the important informations like private keys on a secure place in no one even know but only me. They cant hack my bitcoin for sure. :)

Must you be living inside the cave for centuries didn't you? as for example, the recent hack has happened to bitfinex and loses about millions of dollar, and it's just one of many which is fortunately leaked in the media.
Just imagine if some bitcoin users don't really care about the security of their wallet and ended up targeted by hackers and finally getting hacked, there might be so many people out there who have been hacked but didn't publish it into media.

Any computer on a network with Internet access is hackable and so if you're careless enough to leave your private keys on a public computer or an unprotected computer then you're at risk and you can be hacked in no time and of course funds can be transferred between wallets.

The computer will be hackable if you accidentally downloaded other hacking software or if your computer infected by a virus that gets data in your computer so if your computer is infected and you login your details or save your wallet in your computer it is posible to get hacked by hackers.

i agree with you that is impossible to hack bitcoin from their wallet because bitcoin wallet is much more safe and secure and no one can hack any bitcoin wallet without any password.

Bitcoins are digital cash.  And cash can be stolen.  So, whoever has the secret key for a bitcoin address can send the bitcoins wherever they want.
If anyone gets your private key and user key in any way then your bitcoins can be easily stolen from your address. That is why it is not really impossible.

You think so? Then why there are cases that bitcoin has been hacked or stolen even there is a strong password that is set to a certain wallet?

To be able to make bitcoin being a secured thing then make a way to have it unaccessible in the world of WWW (World Wide Web). Basically a wallet that is not a web one. Different hackers have different way in hacking a certain thing especially when they are serious in doing something illegal to a certain target. That password thing is not an assurance that people are safe to hackers if they have it.

If one can manage to hack the wallet of exchange or wallet service provider then the hacker won't need your password because you have already granted permissions to manage your bitcoins and private keys on your behalf to that service provider. Password for online wallets is just for your access to the account, exchanges or wallet service providers already have your private keys.

Now based upon the security features wallets have we can say strongly that it can't be hacked. At the same there are lot who have got hacked due to their mistake or carelessness. Hacking is possible, so giving importance and safe guarding it through high security features is good for the user.

Nowadays hacking bitcoin in wallet without password is possible especially there are so many hacking tools out there but if you're using hardware wallet that would be another thing I think they will have a hard time to hack your wallet.

How about installing a back door and collect their key strokes and then hack the bitcoins from their wallet.It is possible to do so if you system is not secure. So always use a secure system if you are dealing with bitcoin.

I'm not a hacker, but I guess it could have been done. if the skill that they have been very great, it's not a difficult thing. but, the thing is, if they want to take your bitcoin or not? because I think they are always eyeing bigger things, such as trading sites, or the like, which can make them a profit enormously.

For this very reason if your serious about your bitcoin security you should have a separate system for bitcoin alone.
Kept offline unless syncing wallet or sending fund. Not used for "general" browsing or downloading.

There is also a script written in python that can bruteforce attempt seed combinations.
I have tested it with electrum and managed to crack a wallet seed in around 14 days.

So it is possible. Nothing is unhackable.

I don't think that they can hack huge amount if bitcoin if they want because if it were so, bitcoin's holder will pull out their money from it. Also, even you're skilled enough in hacking, if your target is also smart and his account his secured, your time will just be wasted. Bitcoin was designed for the security of transaction. It has a capability to keep the transaction anonimously, hence the accounts's identity is impossible to determine.

I don't think so since you are the only one who knows your password and security it is surely secured, that is why do not disclose any information of your bitcoin wallet to anyone to make your money safe and secured.

When i read this , i was like has some , who was drunk , written that topic.
Like how can a person hack his own account .
If a person does any transfer of money with his account , that term is called TRANSACTION .
But when i saw that you were a Newbie , i understood that answering this was a waste of time .
But if the question you wanted to ask was this ' Is it possible that someone who got into my account logged in already
can transfer money to his account? ' . If this was the question , then the answers depends on the wallet.
Some wallets ask for re confirmation , like the pin no. or something . So he cant transfer unless he knows that pin.
But if the transaction can be made without any verification , then he can transfer all your money to his account.

I wouldn't conclusively say it isn't possible because there was some kind of hack/bug issues in 2010 when a single person generated about 184 million bitcoins but the actual block reward then was 50 bitcoins; the issue was solved after 5 hours though but even with that in mind I don't think your wallet is immune to cyber attacks.

its not easy now , and thanks to cryptography. its so hard to guess passwords. yesterday i was reading one Chinese professor now able to crack SHA-1 but after years of research

This is true,hacker would really waste of his time on hacking a particular target specially if that target set up the most important security on his wallet.Bypassing and bruteforcing it would really time consuming or useless at all. If a hacker would trying to hack my wallet i would say goodluck to him 8)

People are always concerned about security of the code, of wallets, blockchain and I don't know what else, but the weakest point is ALWAYS human.
There is much higher probability, that your wallet will be robbed, just because you have left your seed saved in txt on your desktop, or because your password is "1234" or because you installed a cracked software on your computer. ;)

Even if you are the only one who knows your password and security pin and even if you dont disclose your information the hackers may still get into your wallet. Hackers uses viruses that enters your computers then it collects information from any login information that you have done. After which they will use that information to get your bitcoins out of your wallet. Aside from that even how solid your firewall is if you have stored a huge volumes of bitcoin into it hackers will try to get your bitcoin in a more complicated way. If you heard about bitfinex and other big sites that holds volumes bitcoin declares being hacked then how much more an ordinary wallet is.

Possible yes, because not safe 100% in the internet
but it depend on you too how to safe your wallet from the hacker
dont forget to use F2A and Sms verification for security in your wallet.

I have read some comments that bitcoin wallet can not be hack because of the strong security feature and probably system administrators are maintaining it for hackers to crack the codes but a lot are trying to say that the system are not 100% and has a hole that hackers are tying to take their opportunity towards it, and online wallets have many flaws that skilled hackers can navigate and be fish in no time, and in my opinion that definitely online wallets are not 100% safe and has flaws to it's system cause I have expirience this kind of attack that hackers did their best in invading the system that I can't believe they can truly hack through it.

I had read so many posts before about the people who were a victim from bitcoin hacking. Maybe they had clicked some phishing site that's why their wallet got hacked. They are not careful on which link to click. There are many scammers nowadays so be careful on clicking email addresses and URL's.
