If you're an enthusiast of both the Bitcoin currency and the Windows platform, you'll want to beware: there's a Bitcoin-specific trojan virus out there that will scan your computer for the unencypted wallet file and acquire your hard-earned digital capital.
Symantec says the found source code for the Infostealer.Coinbit trojan circulating around underground software forums. By default, the file that keeps record of your Bitcoin balance is unencrypted, and unless you secure that file yourself, it's very easy for someone to steal the file using a simple system search. The trojan essentially replicates that process, by locating the file then either emailing it to the attacker or uploading it to their server. And considering that a single Bitcoin is roughly worth $15 USD right now, that's a file you'll want to protect. Stay vigilant. [Symantec]
