Title: Possibly Hacked
Post by: Maxicap on February 18, 2016, 02:03:23 AM
So I've only had my wallet for a couple months, casually buying and selling bitcoins.
About a month ago I mysteriously lost about $30 USD, it said that I'd sent the coins the night before but I didn't remember doing that.
I just passed it off as me being tired and making a transaction I didn't remember.
Well it happened again, with the same amount, and I'm pissed off.
If anyone can give me advice on what to do in this situation please help
On another note, the blockchain address said the coins were sent to the middle of the Gulf of Guinea. Yeah, definitely wasn't me....

what doesnt make sense to me is the fact that if you were hacked , why not just wipe your wallet? why take 30 twice?

Doesn't seem to me a hack either. The location in blockchain doesn't actually mean the location of transaction.

^^ this... it's one thing when people steal credit cards and try not to make gigantic purchases so that it doesn't get frozen and you don't notice, but with a bitcoin wallet there isn't really much risk of getting caught or getting in trouble, so I don't see why they wouldn't just take everything at once. I'm guessing you haven't been hacked, but I could be wrong.

If you were really hacked , first thing you can do try to scan your computer to check it's infected by malware or not, some people lost their bitcoin due this malware, steal every information you type on your computer.

It could turn into something much worse so the best idea is to just wipe the whole computer and just make sure everything is removed from it.

All security online wallet is always can be hack anytime its just made by human so they can crack or hack it anytime..
But you prevent it buy checking all link before you login and make sure you have updated anti virus(kaspersky is better for me to use)
Make sure you firewall is always on to prevent from remoting.. after doing this steps you should reset your password and change it with 13- to 16 characters dont use password below 7 because there's a software that can crack it..
Also put some capital letters.. To make sure they can't login...
You can also try base 64 code encrypt and decrypt for password..

you might have multiple personality disorder?

in anycase you really should keep >90% of your coins offline

go to : bitaddress.org and print yourself a few paper wallets.

If I understand that reference right, that would be 0 latitude, 0 longitude. Which just means it has no location data.

that is the bitcoin node that broadcast the tx to the network not necessarily the owner or sender of the bitcoin.
move your mouse over to the "?" mark in front of the "Relayed by IP" and it explains what that information is.

quick question..

is your wallet password protected and is 2fa enabled?


if no to either of those, do it..

I had some of those nights too, when I were younger. You wake up the next day with a burning sensation in your ass and a $100 note in your hand. *JOKE The first time you thought your wallet were hacked, you should have changed passwords or switch to a new account.

I hope you are considering it now, or you should stay away from the stronger drugs. ^smile^

I just I'm not sure.
Better to use cold wallet for storing your coin, just don't use online wallet, exchange wallet, even if just for daily spending, better use mobile wallet for daily spending.


Title: Re: Possibly Hacked
Post by: bitbaby on February 18, 2016, 06:42:09 AM
Which wallet were using?

Which ever it was you should have considered it compromised when you lost the bitcoins first time, stop using that wallet, move your funds to another one, format the pc and install security softwares and if it was a web wallet then make a new one, add 2fa and also change password of your other important accounts.

I'm guessing you haven't been hacked, but I could be wrong.

if he was indeed hacked, the hacker technically took everything. I mean 13kSK.... is wiped clean and 12SA.... has only change in it so maybe the hacker took a pity and left some in the wallet for him or maybe he just wanted to take a round number (0.065BTC)

but to say anything for sure, OP needs to provide us with more information about his wallet type (online, pc, exchanger, offline,...) and also tell us if he used TOR for accessing his bitcoin wallets.

The fact that the amount was the same each time makes it seem like it was not a hack and just some kind of error, maybe human maybe not?


Title: Re: Possibly Hacked
Post by: NorrisK on February 18, 2016, 07:12:58 AM
If there is ever a suspicious outgoing transaction in any of your wallets, switch wallets immediately!

The first thing you should do is make sure it won't happen again. In the worst case if you don't trust your computer fully, send it to an exchange with 2fa enabled. That way, even if you are keylogged, the coins will be protected (note I do not recommend storing coins in exchange, but in this case with low value it may be ok temporarily).

If you were really hacked, the hacker might have left coins in there in the hopes that you might refill it again so he could take more. Definately change to a new wallet with a new private key.

Some web wallets have a setting where 2fa is only required for large amounts or multiple repeated payments.

Attackers of web wallets may be withdrawing small amounts periodically to avoid 2fa.

But I don't think that happened here. I think he signed up for a periodic thing.

Post by: btcltccoins on February 18, 2016, 08:42:57 AM
The first thing is that you should make your wallet with a very strong password and never share it with anyone. Moving your coins in the cold storage is a good idea only if you don't have to use that regularly .

With web wallets, the web wallet has the private key so they can send on your behalf.

But for the private key they have to get login first. Where and how can they get our passwords ?

So when I set up coinbase to automatically sell $200 worth of bitcoins once a month, and it does it without me logging in, how exactly is it doing this?

No I haven't configured it to do this, but I can.

I don't know how all the web wallets work, but with coinbase only the coins you have in their so-called "vault" require some type of pass phrase to unlock. The normal account, the private keys are not tied to your login password or a passphrase.

I don't use their vault, I use cold addresses instead for similar purpose, so all my currency at coinbase (which I keep small) could be spent by someone who got into my account - though large amounts or several small amounts trigger 2FA but single small amounts don't (mainly because I don't need it to, I keep less than 1 BTC there)

isnt coinbase an exchange?
ive personally never used them, but your coins are probably in their hot wallet.

meaning you dont have any private keys for them.

they have a vault, that you move your coins to.. which you own the keys to, but i am fairly certain it will be encrypted.

hah i just noticed this..

that map has nothing to do with the address YOUR coins were sent to.. its the node's ip that saw the transaction first and relayed it to the rest of the network.
its almost never accurate tho. which is why it shows in the middle of the water.

It is not good to be hacked. That is very bad. But you must secure your stuff good with good passwords.
I think you should not tell everyone what you have. Otherwise they are interested in you and then you will going to hack you.

While hacking is not a simple task. I must agree that it can actually be that simple if you dont protect your user credentials your passwords emails etc. You can't really trust anything nowadays you now.

web wallets are different from each other. a service like coinbase is something like what you said. (I don't know if they have the auto pay option) but assuming you set such option they deduct the amount from your "account" not bitcoin address. in wallets like coinbase AFAIK you don't have access to a single bitcoin address/private key they have all the access and you only have an account.

but other web wallets like Blockchain.info is different. they don't have any access to your funds/private keys the wallet is created in your browser, encrypted in your browser, decrypted in there too and they are only keeping an encrypted version of it on their servers with no access to your funds whatsoever.
this is what people usually don't know about these services.

That's good advice, but don't use your phone to enable 2fa on an exchange if its been connected to your computer. Use a phone that's never been connected to the potentially infected computer in case your computer managed to infect your phone. It's better being safe than sorry.

What platform was this on.
If it was a software wallet then it is unlikely that it could be hacked... but not impossible.
I suggest that you spread your savings around or use some old storage for coins that you don't need to be "hot".

Even, just use 2FA on a platform like coinbase or blockchain.info to send your bitcoint too and keep them secure.

but other web wallets like Blockchain.info is different. they don't have any access to your funds/private keys the wallet is created in your browser, encrypted in your browser, decrypted in there too and they are only keeping an encrypted version of it on their servers with no access to your funds whatsoever.
this is what people usually don't know about these services.

The OP never said they were taken from a private address he controlled.

To clear some of this up.. It was not a web wallet

is it a "brain wallet"

tell us what program it is..

core-qt? electrum?

perhaps you downloaded it from a phishing site.. not all wallets are legit and you should only download them from the source.

So when I set up coinbase to automatically sell $200 worth of bitcoins once a month, and it does it without me logging in, how exactly is it doing this?

No I haven't configured it to do this, but I can.

I don't know how all the web wallets work, but with coinbase only the coins you have in their so-called "vault" require some type of pass phrase to unlock. The normal account, the private keys are not tied to your login password or a passphrase.

I don't use their vault, I use cold addresses instead for similar purpose, so all my currency at coinbase (which I keep small) could be spent by someone who got into my account - though large amounts or several small amounts trigger 2FA but single small amounts don't (mainly because I don't need it to, I keep less than 1 BTC there)

Secure by design
All your data is kept encrypted on your machine

so unless someone else knows your password or you made an insanely easy one like password123 should have been safe..


do you have as roomate or girlfriend that knows your passwords?

at any rate, id make a new wallet.. and move your bitcoins to it..

make it with a secure password (10 digits or more).. using CAPITAL, lowercase, 1234567890 and !@#$%^&*() characters.

I already got hacked as well. I had a blockchain.info wallet with a very bad password. it was hacked in just a few days and I didn't had too much in there... so I imagine that if you have a little more they can steal you even faster

The transactions also require you approve on the email. so your email was also hacked ?

Reading this post i am feeling insure...why can our wallets be stolen so easily?
We have online bank accounts and they never get hacked...so why bitcoins online wallets get hacks too easily ? ???

You must have possible used a service that charges you $30 every month and your bitcoin account must be linked to it (ponzi website, forex or any other website). Hence it's better you open a new wallet and store your coins there instead of your old wallet. If it was hacked, you would have lost everything.

The last couple of days there has been a number of attempts to brute force a lot of blockchain.info wallets, dont know how they got the id's.  but i would guess as has already been said that you where not hacked, does anyone else have access to your wallet?

Another site cant take bitcoin from your wallet like a direct debit, they could only do that if they had the privkey ??? in which case its not your bitcoin its theirs....... :o

it could be people that make aliases the same as their username here.. or their real name.

that could be a very bad idea.

Yes, people tend to use the same ID at many different sites, or related IDs at many different sites.

My bank requires a user ID contain both upper and lower case and a digit to try and avoid that, because most user ids that people reuse are either all lower case or several easily discernible words with ucfirst.

That's in addition to their password requirements, and 2FA.

An up to date anti virus is the best way to protect offline wallets stored in your PC. if it was an online one,well id recommend you to completely stay off online wallets. besides that,there is nothing you can do to get your money back,just be more careful in the future.

the blocktrail web wallet seems very secure..

i have 2 passwords i have to enter to get to the wallet.. first is the site login, the second is to decrypt the wallet..
then i have 2fa enabled so they need that code as well..

you have access to the private keys.. altho they are encrypted.. so you need to keep the 2nd password handy if you ever want to import them to another wallet.


they also have an android app. but i also dont see a way to increase the default fee. :/

Brute force attack .. It the responsibility of the Block chain to protect their site from Brute force attacks.
They should make their network secure . It will be benefit form them and for ourselves also who keep an
online wallets there.

Same Id and more importantly same passwords on the different sites in not a good practice. You can easily loose your bitcoins if one of your password is hacked.
Always keeps the passwords for your wallet

just a theory since i am not using Multibit but you might want to consider this or ask around in the appropriate section here: https://bitcointalk.org/index.php?board=99.0

AFAIK MultiBit HD charges you a fee in order to use it, it means that you have to pay an extra amount of bitcoin to the developers for each transaction, but i don't think it is $30 (maybe accumulated a lot of these fees over time and paid them in one place?!)
