I didn't turn on my computer yesterday. When I started my bitcoin client today, I saw that 5.046596 BTC had been sent to some addresses the day before. The strange thing is that's the exact amount of Bitcoins I sent to my LocalBitcoins address and retrieved back on Friday. My wallet is AES256 protected with a strong passphrase and this is a Linux box that the only person has an access to is me. The transaction on blockchain.info:

Have you checked your system for any file irregularities?

I would say you may have been hacked/compromised.

Everything seems as usual. The only difference is that the address I used for that transaction was a VanityGen generated one. I had imported the private key myself using the debug interface.

Yep.  Looks like you hacked yourself.  You generated a vanity address, posted the private key on the internet, and then transferred bitcoins to the address.  No surprise that someone took the coins.

If you acquired a vanity address from someone then they too have the private key.  If hey do they can control your account with out you being hacked.  all they need to so is add it to their wallet and spend your coins.  the only safe way to acquire a vanity address is to create it yourself.

I should revise my posting, after Reading the previous post, in that you need to keep your private key a secret and not post it the the web.  Good catch Danny.

Not my catch. OpenYourEyes posted the link showing that the OP put the private key on the internet, I just took it the next step to explain what happened.

I guess I would have seen that if I had Openned My Eye.

You know, we facepalm, but that's a big problem with BTC right there. Random Q. User has no idea about cryptography and what all those keys do and why you give out one and not the other and oh, I'd better give you both, I never know which one is which, all those numbers, haha, when I was young we didn't have so many numbers you know. numbers were shorter than, but it's the times I think everything get's more complex, oh so it worked thank you young man.

And there you have a recipe for disaster.

That's why I always suggest new users to services like blockchain.info. I've had newbies complaining to me that they've reformatted their PC and have their wallet password, but their coins are lost.  Lips sealed
