Hi all,

I am the owner of 19BWxdCtmTcWupG6tQjXZD7F4hDd6ftEri

I logged in and had a look about 3 hours ago and lo and behold, exactly one Bitcoin has disappeared.

The wallet is kept by Blockchain and I have emailed them. Their response is that they have no control over it therefor nothing they can do. \
I have read several issues Blockchain have had in the past and wonder if it has to do with that?

I have relocated the remaining Bitcoin in another wallet which is with Blockchain at the moment still, but protected with 2 factor authentication. But I do not comprehend how this could have happened - it seems almost surreal. I had about 14 Bitcoin in there and whoever took it, took exactly one bitcoin. Why not everything?

Does anyone know what is going on or can unravel this for me?

That seems strange. Maybe your bitcoin is sent by yourself unintentionally. If not then you for sure have forgotten the exact number of bitcoins you had in your wallet.

I don't think that your bitcoin was taken by a hacker. Because him would take all your bitcoins and not only one.

And at the end blockchain wallet have problems. One my friend had lost its bitcoin from this wallet time ago. I would suggest that you use coinbase. Which have two factor auth to.

My guess it's a hacker. He showed you that your wallet is compromised, and he took 1 Bitcoin for payment. You did exactly what he wanted you to do, by moving the money to a more secure wallet.

We have seen this before, I would just need to search for it on Reddit. The hacker removed all the coins, and he made it public. The people who could prove to him that they owned the compromised addresses,

were reimbursed with the full amount. Hope you learned something from this. 2FA on online wallets, is a MUST not a option. Wink

Did you store your private key anywhere insecure? That is what I think of.

You could have 2 factor turned on with a wallet. But if you lost your private key it would not matter that is game over.

I was also the scene, when I want to log suddenly blockchain requested verification email ..
When I see in my email, no email from Blockchain ..
I've been many times to send a message to the support of blockchain, but the response was zero ..

I too had bitcoin come up stolen from a wallet I had on Blockchain.info , but I cleaned some spyware malware and all kinds nasty lil things i didnt know were on my computer using malwarebytes and windows defender and Ccleaner, then i went under the security settings for the wallet and whitelisted my I.P. address (I have static IP never changes so that helps :-)) so far twice choosing that security option as stopped someone from accessing my wallet... clean your computer change your passwords and take extra security measures that the wallet offers

What you are suggesting in a good advice, but it still doesn't explain why the potential attacker chose to take only one bitcoin from his wallet.
Like previously stated, it's quite possible that the person who took the coin is someone op knows in real like, who had access to his PC, but also doesn't want to do him extreme loss.

Also, whitelisting IP's is not an option for many people, because they're on dynamic IP like myself, so someone not well informed might just lock himself out messing with whitelist settings.

It seams that the bitcoin stolen from you is still sitting there where it was withdrawn (https://blockchain.info/tx/b53833d9f8ff13a11b5ea931b25aee1dc763bdcb701fc94da7f2be21ae5cfb52)
I would advise you to take a look at your browser history to see if there was any activity directly on your PC, because there's no chance in hell thief would take only 1 bitcoin
from your wallet, they would most definetly take all, but as a security measure you should update AV and scan computer, take a look at active processes for suspicious ones, and
check start-up exe's in registry just in case.

Who do you live with? Do you maybe have kids or roommates that are low on cash? Do you ever step away from your computer to goto the bathroom or get a drink while logged into your Blockchain wallet?
That would explain it, including why it was only 1 BTC instead of all 14 BTC.

I agree with him, since bitcoin is still sitting there where it was withdrawn, observe those who could have access to your PC, you just may be surprised with what you find.

This again highlights the huge weakness of bitcoin as they are stored and protected (not!) at the moment. If people loose money in a banking account most of the time they will get their money back. For bitcoin.... it's just "so sorry, too bad".

You're so wrong, this is not a bitcoin weakness but rather people's carelessness of keeping their bitcoins in a web wallet, it's like giving your money to a stranger and hoping nothing happens to it.

I don't know what happened to OP, I don't think it was a hacker or something like that because they would have swept the whole wallet but whatever it was I would suggest you to learn about Electrum and cold wallets and move your funds asap or else you might end up losing them all.

You are right, unfortunately people coming to bitcoin have a hard time understanding the importance of securing their funds. They need to wrap their head around that they are their own bank now and they need to make sure their money is safe. Backups, maybe cold wallets, antivirus and so on.

You probably know... nearly nobody thinks a harddisc can break until it happens. Then you start to back up things.

Unfortunate story bro but unfortunately this does seem a little like user error. Why didn't you have 2FA?
You will have this as a harmful lesson in storing your bitcoins securely.

It is puzzling why they only took 1 bitcoin as opposed to just swiping all 14. I can't figure that out, this to me tells me it can't have been a hacker?

It sounds stupid but did anybody else have access to that wallet? Are you 100% sure you didn't send that single bitcoin somewhere and forget? I just can't understand why if somebody was willing to steal 1 they didn't steal all 14. Maybe we have a thief/hacker who sort of has morals Grin

Lol no....I was quite sober. half hour before that I moved something.

BlockChain don't seem to respond with more than the following:

"I'm sorry to hear of this trouble, but the bitcoin network is designed to make chargebacks impossible. Blockchain.info never has access or control of a user's bitcoins in any way, which means only the end user has 100% control over his own bitcoins. This means we have no power to stop or reverse a transaction for you, or even know what exactly happened here."

I will keep pressing them - like I said my main concern is if something strange happened in their wallet - there have been a lot of stories of BlockChain wallets screwing up so I just have to find out which it is - whether I have been actually hacked or whether something has gone wrong with their wallet which many people have seemingly complained about, when I searched around the net.

Find it strange that they are not more forthcoming, considering the amount of issues that they have had with wallet one would imagine they would want to investigate and figure out.

This sounds really strange.. Are you sure you didn't move the funds yourself when you were drunk or something? Wink

Can Blockchain provide log information about the user session which moved the btc, IP address, operating system, browser type etc? That can help try to prove to them that it was not you, therefore be more helpful and friendly to you.

Also I suggest you keep control of the Blockchain account containing the Bitcoin address that was stolen from. In the future maybe the authorities may be willing to investigate such crimes (when 1 BTC = 1Million USD!), so you need to prove you are the owner of that address.

I have no idea....I am busy talking to BC - but so far have had the blunt response - sorry bud it's gone bblabla.

It is just so bizarre that only 1 Bitcoin would disappear if hacked - makes no sense at all.

Anyway have 2FA enabled now but I'm going to have to move my Bitcoins as I feel very insecure with Blockchain right now.

I would recommend you use Electrum if you want a SPV wallet or Bitcoin Armory if you don't mind running a full node.

Blockchain.info had bugs in their random number generator before that caused many people to have the same Bitcoin address in their wallet. I wonder if that is what happened again, and some other person had OP's address too but didn't fully realize what happened so didn't clean the address out and only tested it.

how is it weakness of bitcoin?!!

as i understood from OP , he didn't have 2FA enabled on his account. i have seen a lot of this which led to losing bitcoin stored on blockchain.info 's wallet. besides it is a well known fact that online wallets aren't exactly the most secure place for storing bitcoin.

so it would be the service's weakness and not bitcoin

That's the thing - I don't think it was a hacker either - hacker would have taken everything, and also, would have had to authenticate via my email if logging in from somewhere else - even if he/she knew my password.

That is why I was thinking it could only have happened with a virus, with my session open, or there are these issues which I assumed had been sorted with Blockchain: e.g. this - https://www.cryptocoinsnews.com/gentleman-hacker-returns-stolen-bitcoins-blockchain-info/

No it did not have 2FA enabled - I just moved the remaining ones (Also a Blockchain wallet!) to another Blockchain wallet that does have 2FA while I figure out what I am going to do next.

But that still does not explain why it happened - because I have logged in from another connection or browser or pc before, and it only allows me in once I have authenticated via email as well...
