Hi,

Just a word of warning to everybody out there from somebody who is now forcibly out of the Bitcoin game.

I hold a BTCT account. This account was compromised, I had locked the payout address to my own wallet.

My various shares were all cashed out to my address.

Subsequently my wallet was emptied (including some 15 or so other bitcoins I had)

My Wallet was covered with a 25 character long passphrase. I can only assume that my home computer has a key logger installed.

1EYz2DwJy2xj3o7cPtVsFPXX6C2moMrYXj now has over 50 bitcoins of mine.

Given my Bitcoin investment money was set aside for my young family, even though its not a huge amount of money I am completely gutted.

Cheers

Stop using IE and OPERA .... use google chrome or firefox. Most exploits works on ie and ff. Also do not download flash "updates" you are asked to download from various sites.

But most of thieves use and exploit and traffic to build a botnet and only ie and opera can be exploited.

START READING THE POST BEFORE COMMENTING.

He is an OSX user and only used / accessed the wallet on OSX.
Yes thats right, he had a trojan on his OSX installation, it does happen.

a trojan is installed on the pc in 2 ways :

1 - you download something and get infected ... and in this way it doesnt matter what OS you use
2 - you visit an website iframed with an exploit link and get infected ... works on windows and ie / opera only from what i know

but also on the market exists private exploits ... never had access to one so i dont know what os / browsers can be infected

if you get infected with malware , the guy who runs the botnet see everything you do on the pc ... get all your passwords , bank acc , cookies ... everything . even he can transfer money from your bank account without log in if he have an ats inject .
