Bitcoin Forum

There are currently three ways to steal Bitcoin. First, hackers infect crypto asset exchange servers with special malware via e-mail, websites and popads and infiltrate devices. This happened with the Binance hack last year.
Second, take apart the Bitcoin hardware wallet and get the seed phrase. This has been practiced by Kraken against Trezor.
Third, hacking into the Bitcoin blockchain network itself through “51 Percent Attack”. This third method is considered expensive, but has the potential to get the largest loot than the other two methods. This third method, according to observers, will cost up to US $ 21 million.

All those attacks are very unlikely.

THe first you are not really attacking Bitcoin, but a person. You need to get this person e-mail and sent it a malware and hope this person gets infected. No, this wasn't Binance's case. Binance suffered an attack through their API.

The second attack you mentioned is impossible. You cannot extract a seed phrase from a hardware wallet (unless it is a shit one).

And a 51%attack in the bitcoin network is so unlikely that it is almost impossible. After you spend all those millions you would be kicked off the network right away and you could do only 1 transaction.

And nobody controls 51% of the network, the largest pools have about 20-30%.

There are currently so many ways to steal Bitcoin, definitely more than 3. There are also many ways to hack Bitcoin wallets.

But to hack Bitcoin itself, there is only one way. And that is to take over at least 51% of the network's mining hash power. Indeed, that is very costly and therefore extremely unlikely to happen, next to impossible as a matter of fact. And the potential loot may not be large as daydreamed.

And, again, it certainly provides the attackers more incentive to use the hash rate in favor of the network than to bring it down.  

It is good that there is a thread here for hacking bitcoin or the wallet itself. It can help our fellow miners and traders to be aware and protect their savings that's why it is indeed a good thing that the poster posts this kind of topic. And even if I know how to hack a particular wallet or the bitcoin itself, I won't do that because If I want to earn coins, I will do that with hardwork and determination to earn by means of trading and not by stealing someone's coins because karma is real.

I quite agree for the first two points, but with regards to the 51 Percent attack, it will not gonna happen why? Because us knowing that most of the hashrates are distributed makes us trust bitcoin further. If we figured out that most of the hashrates are handled by a single entity or groups, this means that there could be interference and manipulation to happen. In addition, the distribution of hashrates to thousand of nodes all over the world makes bitcoin's blockchain purely decentralized.

these are not "hacking bitcoin". so your title i nonsense.

the first and second have nothing to do with bitcoin. it is about security of centralized services and physical devices created by a company. bitcoin itself is secure. it is like posting your private key on a forum and then saying they hacked my bitcoin since that is how most exchange hacks are, they have low security with lots of holes in it and when someone exploits them, they hack their exchange not bitcoin.

and the third one is not exactly affecting the coins one has. it can only create new blocks in place of old blocks, and it is not just expensive it is extremely expensive to perform and actually rob someone because it requires a gigantic transaction to be sent first to someone in a trade where you get something else in return (like selling millions of dollars worth of bitcoin and receiving the fiat) then 51% attacking (that costs millions of dollars) to reverse that transaction. but the problem is that someone who has accepted such a huge transaction will demand a lot more confirmation which means the 51% attack cost goes into trillions of dollars range.

Better to share some sources since names of such big exchanges were stated here. But anyhow, I remembered my experience when they hacked my crypto wallet. I have signed up using my email address with the same password I used in my wallet to that of some fake mining websites. They stole my crypto coins. That's my biggest downfall that time. And a lesson learned for me, too. Better not to sign up with untrusted websites, do not download suspicious apps and do not click suspicious links.

The first 2 have nothing to do with BTC and the last one is almost impossible, in case of Bitcoin at least. It´s just like whne the Twitter hack happened, it was Twitters fault bot Bitcoins.

there is no way bitcoins can be hacked, unless people are careless about protecting their wallets, somehow I'm still not sure there is a way to hack bitcoins from someone's wallet, as you said there is a market that has been hacked, I am more sure if the insiders do it was not hacked by outsiders

They're more like just taking advantage of the vulnerability of humans and take advantage of that to take their coins. You're technically hacking wallets instead of Bitcoin itself. It's like you're saying that the form of someone stealing money is hacking the fiat system itself. Stealing from a wallet is different form Hacking and heck, you're even talking about two different things with the 1st and 2nd, since you're technically attacking the "wallet" that contains Bitcoin, not Bitcoin itself.

As for the 51% attack, it isn't a hack but rather mostly just altering the records? The core of what Bitcoin is wouldn't really change. And, 51% attack isn't more of a hack, it's more like using money to buy up 51% to enforce what you need to do to earn a profit, so in a sense, it isn't hacking. After all, you're technically using the inherent ability of what Bitcoin was given, the ability of 51% attack, so using hack is a bit of a stretch.

This is more like "How to Steal Bitcoin from other users"

The only legit way to mess with Bitcoin is the third option but that happening is unlikely.

Let me summarize your post in 1 image:

Your "hacks" aren't hacks at all.
And they don't "hack" bitcoin.

As much as you are keen on getting merits, please stop posting such nonsense. It really hurts reading that.
I simply don't know where to start..

Regarding 1):
"Binance hack" because people were dumb enough to install malware on their computer? No. That's not "a binance hack".

2)
You are reading stuff you don't understand and writing stuff which doesn't make sense.
You make it sound as easy as booting up your PC.

3)
21 Million? Not even close.
You wouldn't even get the hardware for that amount (given that there can be that much hardware produced for you..).

Choose big exchanges where they have so strong security and attack protections. It is how you choose and use exchanges.

Moreover, secure your account from your side: by secure the email you use to register exchange account (with strong password, 2FA) and don't forget to have healthy and careful web surfing and email using. Next one, secure your exchange account: strong email, 2FA (not use SMS because SIM swap attacks), don't resuse passwords.

Only visit official sites and don't log in any platform from search results if you don't do double checks.

Last but important, don't store all your funds on exchanges, one or multi exchanges. Store most of your funds in non-custodial wallets.

In fact, you can if you come into possession of a device that has a security vulnerability which makes it possible. Such a vulnerability was found some time ago in Trezor, see here -> Trezor&Keepkey - Unfixable Seed Extraction - A practical and reliable attack! (https://bitcointalk.org/index.php?topic=5180137.0), and you obviously forgot that you post in that thread.

Of course it would be best if this security flaw could be fixed (this is not possible), but it can be prevented by adding a passphrase or by using SD card (https://bitcointalk.org/index.php?topic=5241004.msg54233855#msg54233855).

There are 2 proper ways to steal (not hack) bitcoin:
1. Fool people to either send you their coins either give you their credentials/private key/seed. (Or make an ICO, heh).
2. Force people to give you that (see the 5$ wrench security issue: https://xkcd.com/538/ )

Technically, these are never ever called hacking bitcoin. Actually, there is nearly no way bitcoins can be hacked unless some careless bitcoin holder send the private key or backup seed to someone and lose these two after being infected by some malware, which is previously been discussed a lot in forum about how can you usually get infected and of by the different kind malwares.

That very first step though. What do you think of the exchanges? it's like any first-person shooting game where you can inject some .dll and you'll finally be able to hack its backend and you'll get a whole vision of the game and your enemies camp?

As per the news about that Binance hack, the hackers used too many methods. This time, only someone who hasn't heard of these phishing emails or scam emails will click those links attached to an email.

lmfao I wish I saved my sMerit to give to you, this totally captured how I felt reading OP's '3 simple ways to hack bitcoin, crypto enthusiasts hate him!' garbage

I forgot that this vulnerability could not be fixed in Trezor... Good remembering it.


This is so true. If an exchange is worried about a transaction of 20 million USD, the exchange you just wait for 10-20 confirmations before crediting his account, making the transaction really irreversible, even with 51% processing power.

The title of your thread is somehow sketchy, maybe you should change it in to "3 ways on how hacker steal bitcoin",
because your title can be possibly thought as a tutorial to hack a bitcoin.
Just my two cents.

Also if you are exploring the internet, don't click any ads or suspicious link that might bring you to another platform or make you download files from unknown source. Some malware are downloadable and can enter you computer when it disguised as a legit software. So be careful on downloading from any links or websites especially if you have no idea what is it about.

With that, they can track all of you information in your computer to hack your bitcoin so be aware with that.

of the 2 ways that you mentioned about the right way to steal but not hack are the most common and widely used ways today. especially those related to ICO, IEO or the like. We know that ICOs, IEOs are ways to raise funds quickly. There are more and more fake ICOs and IEOs with scam projects that can trap everyone. making ICO or IEO is very easy, when you get a lot of money, they scammers will run away with a lot of money.

There are many ways that these hackers can infiltrate your device and steal your coins or even infiltrate a server and steal the coins on that server, but the one that’s mostly known is the email method that’s being used by them; most hackers makes use of this particular method because that’s what is easier for them to make use of, so they go for it. So, if you’re making use of cryptocurrency, and not just cryptocurrency, as long as you have any business to do online, you have to be very careful and be aware of every means that can be used by these hackers to gain access to your device and steal your information or even gain access to your seeds and then cryptocurrency wallet.

Sometimes these hackers can create an application and put it on Google play store or Apple store. Google and Apple do check out for these dark applications, but some of them do slip through their sight and get on the platform and people who are not very careful will go ahead and download these apps, which will give the hackers access to plant malware and steal their information. That’s the same thing with plug-ins that you’re using on your browsers, you have to be careful with the kind of plug-ins you install, best to stay clear from them and only install the ones you’re very sure are good.

Luckily, hacking still requires physical access to the device, and I'm sure this attack vector is even quite harmless compared to those users who voluntarily hand over their seed on phishing sites that pretend to be Trezor sites. However, for all those who use this HW, put a strong enough passphrase and hide it in a safe place separate from the seed.

Thank you for this very important post. Through this post we have learned a lot of important information. We hope you will continue to share such important information with us. Through which the whole community will benefit.

Bitcoin Clipper Malware: changes the bitcoin address of the recipient from the original.

There should be many ways to hack Bitcoin, not only the 3 ways mentioned in the opening post. Moreover, the occurrence of Bitcoin
being hacked is not because Bitcoin is easily hacked, but because it is the fault of users who are not careful in maintaining it Bitcoin
they own. If we can protect Bitcoin properly, it is very unlikely that Bitcoin will be hacked.

Is this also a form of FUD?
Or this is real FUD?  ;D

I mean, I don't really know where you are getting at.
Is it a warning for hacking prevention (sadly, I didn't see anything on how to prevent it), or is it just to scare off some newbies?

The easiest explanation out there.
Thank you Sir.

You picked my wallet but the money is still there.
Bitcoin is still there.

There are only few of all possible ways to steal Bitcoin. For example, you didn't mention scams like Twitter hack and phishing.

Don't make conclusion on every thread before reading replies to the Opening Post. Just go through the replies on the first page and you will find out why this post is utter nonsense. You can't say Bitcoin is hacked when some hackers were able to get the hold of acccounts of some cryptocurrency exchange working on centralized model.

Also, I don't know how OP calculated that $21M figure to perform 51% attack. Don't know if it has anything to do with the supply of bitcoins that OP may have misunderstood.

only a fool would do this just to hack bitcoin, so once you hack bitcoin and get tracked by the police you will get a new case. So I think this kind of action is not for anyone

Stealing Bitcoin is not hacking it, so the name is misleading. The first hack is the hack of the exchange, not of Bitcoin itself. The second is at best about hacking Trezor wallet, but definitely not Bitcoin. And the third is finally about Bitcoin, but I still wouldn't call it a hack. Then again, it's almost impossible to do this, and I'm pretty sure an attempt would cost way more that $21 million. It seems that it's even hard to calculate how much money it would take because with Bitcoin it's probably not possible to get enough mining power. The only one who's probably able to pull it off is Bitmain, but this would destroy the company, so we are relatively safe from that. What would be a hack on Bitcoin is quantum computers being able to decrypt everything (if that ever happens), but we're not close to that either.

Your 10 points can be boiled down to 2:

• Compromised system
• Phishing

Those two points also are the most common reason people do lose BTC (or other sensitive data/information).

And further, there is a difference between cryptocurrencies and digital currencies.
Cryptocurrencies are digital currencies. But not every digital currency is a cryptocurrency. That's an important difference.

The article content does not contain too much meaning, apart from the first way out, the following 2 ways who participate in this market also know it.
Do you know how to hack Bitcoin from someone else's wallet address? Don't teach hacked things about this because if they could, they would have done it a long time ago.

You're right bro, I have long suspected that the ones who steal bitcoins on exchange websites are those who work or have worked at the exchange, so they know the weakness of security on that website. It is impossible if people out there know the weaknesses of security on large websites. Even though there were, it was only 5% of the people in the world.

This is the most easiest way to scam people using crypto. I remembered the time when ICO and IEO ran in this industry. Almost all projects were hyped and many of them were sold out. But as the time passed by, scammers made a way to earn using fundraising. Until the time that investors quit in crypto because their capital was gone. Right now, it brought a damage to the entire ecosystem of crypto. Genuine projects were failed because no on wants to risk anymore. If there is, they only give few allocation for their investments.

Yes, indeed it's a kind of a clickbait.
So, even if you have the seed phrase and all BTC is still not 100% safe.

That is interesting way of attack and also seems very dangerous. How it could be discovered and how to avoid address to be changed, that is what I would like to know.

And that's isn't hacking bitcoin, you are just putting malware into someone's computer to generate your own address whenever they copy/paste.
What a possible way to crack bitcoin is having a quantum computer that computes bitcoin certain key in less than a minute, that's breaking the cryptography security and the end of whole cryptocurrency. There are some cases where this has been reported, probably acquired from unknown download sources.

I wonder where such statistics come from, especially regarding the last point. 21 million dollars is not even one percent of the total turnover of money in bitcoins. I.e. it turns out that this method of fraud will not be quite dangerous on a global scale. I think you need to be more afraid of just losing your wallet or forgetting your private key. I have already lost a very large amount of cryptocurrency.

Hacker have their ways of hacking bitcoin accounts may be the way we taught might know be the way they strategies their plans of hacking account's,so therefore everyone have to be conscious transactions and password to avoid hackers not to penetrate to their account's.

Actually there are even more ways to hack a Bitcoin wallet. Hackers can impersonate popular crypto companies, so users download a fake crypto wallet. Don't forget about Trojans. They can enter your computer and monitor your behavior, stealing anything that resembles a cryptocurrency private key. and the most common way is publishing fake advertisements.

Here are three key pointers in moving your Bitcoin hack but there are still some ways for hackers. As science and technology become more and more modern day by day, the level of technology of hackers is increasing also. You can see that most of the hacking is due to their own mistakes. I think the biggest victims of hacking are those who are more greedy online. They want to take advantage of the tempting offers from a variety of online hackers and eventually lose everything.

Scammers are constantly circulating online in various disguises. They are scattered around us in such a way that you will never realize that this person is a scammer. They deceive people by using different tactics at different times. In addition to the three ways you can talk about hacking Bitcoin, there are many other ways to hack Bitcoin. Some people's personal mistakes put them in danger. And if you don't have a personal mistake, then there is no hacker who can hack your wallet.

According to your title and post, only point number 3 that can be called as a way to hack bitcoin.
Because, the first 2 points only can be happen if there’s mistakes on the user side. Not directly to the system or network.

All this is your speculation. Of course, you can steal bitcoin from inexperienced users, but it is impossible to hack the network. Over the years, people have been buying bitcoins, with some holding millions of dollars in bitcoins. I assume that they don't keep their millions on stock exchanges. Those who value their money will definitely take care of safety!

As soon as I read "3 ways to hack bitcoin" I was like oh god.... Here we go...
I think those exchanges were hacked into not the actual wallets. They don't need the wallet private keys since they can send the crypto where ever they want to once they gain admin access.
I would not mind owning an exchange but I would be terrified about this sort of thing going on.

That's way its always good practice to not store all your Crypto in one wallet or exchange because as many influencers and members said "Not your keys, not your crypto". We never know, how secure an exchange with their security nor hardware wallets, and even though its secured how are we sure that they're not going to freeze, steal or hand over it to the government if they confiscate it because of the local law there.

In the world of crypto it is not new the 3 ways to hack crypto mentioned in the opening post, most of the people already know about it.
Therefore vigilance is very important, and also storing all of our coins on exchanges is also not a good thing to do. And for the exchanges
and wallets we use, don't forget to enable 2FA security. And most importantly choose exchanges and wallets which is trusted.

Dude you can actually disregard the last one since it is theoretically impossible ;D. C'mon! In order to pull off a 51% attack you need firt need to acquire very huge mining power up to extent that you can now compete with rest of miners in the world. Even though I do not give you the exact numbers you will still realize how small the probability.

Just keep your private keys safe, stop clicking random links and filling up various forms online so that you will become less prone from such incidents.

The first two points you have mentioned are not directly hacking Bitcoin itself but the person or the user himself for having low security on his things and unknowingly being irresponsible that made the hacker do have access on his Bitcoins. The first point can somehow be manageable by keeping those secured and avoid entertaining pop-ups and strange emails. The second point is the storage itself that is being attacked and not Bitcoin directly once again. Also, hackers do not have concrete or just three certain ways of how they manage to hack accounts to obtain Bitcoin. Surely there are a lot more ways possible that those hackers are capable to do because ordinary hacking techniques are already known by the crowd which makes them think of various ways possible to make their goal achievable and those are not only limited into three way. You have just mentioned some of those which are the most common ways but for sure there are other ways possible which only the hackers know and still not discovered by us.

The first two points could be really manageable if you would make yourself knowledgeable and responsible to take good care of your accounts to lessen the possibility of getting hacked.

So many mistakes within one post...

First of all, these are not ways to hack bitcoin.
If we agree that this is what "hack" means then your title doesn't make sense:

https://i.imgur.com/udhEBa2.png

Hacking into the bitcoin blockchain network? Neither this makes sense. It isn't a computer.
"51 Percent Attack" isn't hack. It is the pool with the most cpu power.

Multiply it with 100 and you are closer. Believe me if it costed **only** 21 million dollars, everyone would make a 51% attack.

The 51% attack can be prevented with sufficient decentralization and rules. How can there be 51% attack  if there is no way to control 51% of network participants or PoW? Satoshi's one cpu one vote (with the principles of Bitcoin) would basically solve this if it was sustainable.

No it is not!

It was explained a few times in this thread what a 51% attack is. This is not "hacking" it's rather exploiting a feature of Bitcoin.

This attack is possible only in theory because in reality you'd need to invest a lot of money before you'd be able to even attempt this and as time goes by it's going to be more and more money. At this point you'd need to rent out a whole nuclear power plant to have enough power to try it. 51% attack is a scary bedtime story for new investors.
