There are plenty of these going around, it's always a good idea to encrypt.

very deadly..does encrypting it really work? cause you dont need to read it or open the wallet.dat - all you do is mail the wallet.dat to yourself then replace it with yours and load up the bitcoin program and voila! all the decrypting is done automatically

I recently created accounts with Dwolla and bitmarket.eu.  I was excited to purchase 8 bitcoins. Shortly after the purchase transaction was completed, my account was magically drained to a 0 balance!

From where did you lose the bitcoins: your bitmarket account or the wallet on your personal computer? There should be some dox either way as to the address the btc went to.

The loss was from my bitmarket account.  My account history shows a confirmed transaction for -8 BTC.  I'm guessing that it's from an unauthorized withdrawal.  No one else has physical access to my computer.  I never shared my bitmarket password.  Can this be key logging?

Thank you for your assistance.

Dunno about keylogging, but doing, say, a boot-time scan with (free) Avast! AV software should pick up if you have a keylogger on your computer.

When a BTC withdrawal is done from my exchange account, the bitcoin public address is shown in full. When I do a trade on the exchange, no bitcoin public addresses are involved so none are shown. Is there a bitcoin public address showing? If so, look it up at Block Explorer and see if there is any usable information there.

How do you look it up in the Block Explorer? I'm not sure how that would work. Do you mean one address at a time? Would it be possible to tell where the coin went?

The withdrawal should show the address it went to. Copy/paste the address into the search box at Block Explorer. It won't necessarily help, but there's a chance it may give some useful data. For example, maybe in a year's time the thief will get caught, and everyone who can show a transaction going into ____ (the receiving address, assuming it's the same address like wallet-stealing trojans might have) can make a claim and if sufficiently documented might be able to get their BTC back. It's a long shot, but hey, depending on the amount it might be worth a bit of effort.

It would be nice if thieves could get caught but that is kind of difficult with decentralized currency.

It's difficult to track someone through the block chain itself. But the thief might get caught in some other way, such as the information being found on his computer after his arrest for a disrelated crime.

That's true if the arresting authority knew what Bitcoin was and cared about that kind of crime. A long shot but maybe it could happen. That definitely would be nice.

So, make a note of the receiving (thief's) bitcoin address and google it every now and then. It might show up somewhere outside the block chain. Maybe, once bitcoin crimes become more common, internet announcements might get made by authorities quoting bitcoin addresses.

i believe i am the exception when it comes to people who use windows, but i have:
a) never used virus prevention program
and
b) never had a virus.

I suspect this is probably false... if you installed some AV you'd probably find some malware.

It's NOT all about practicing safe surfing...  with the huge number of Adobe, Firefox, IE, and Java 0-1day vulnerabilities as well as XSS on public forms, and nothing to monitor the integrity of your OS.

Well written malware isn't something you notice.

Thanks for heads up!

It was a cunning plan to have the funny man be the money fan of the punning clan.

The Trojan might be FUD (and once its not FUD they might use a different crytper), so it's better to just be careful of what you download...
