There's a new Trojan virus in the wild targeting OS X users that steals GPU cycles to produce bitcoins, takes screenshots in an effort to steal personal information, and runs scripts that copy, among other things, your Safari history and .bash_history. This bit of malware, dubbed DevilRobber, was discovered in a BitTorrent download of GraphicConverter 7.4 from the Pirate Bay; there haven't been reports of it showing up in other BitTorrent downloads yet. The virus' most noticeable symptom is that your computer feels extra sluggish from DevilRobber using your GPU, so if your machine in inexplicably slow, it might be worth checking out some of the free OS X anti-virus programs, such as ClamXav and Sophos.
