iBotnet: Researchers find signs of zombie Macs | Zero Day | ZDNet.com: "Malware hunters at Symantec have discovered a direct link between a malicious file embedded in pirated copies of Apple’s iWork 09 software and what appears to be the first Mac OS X botnet launching denial-of-service attacks."
The variants have been found inside bogus copies of iWork ’09 and Adobe Photoshop CS4 which were shared on the popular p2p torrent network. The author of the malware downloaded the original/trial versions of each program and introduced a copy of the malicious binary into the packages. Users who then downloaded and installed the applications from the torrent download would have been infected. It is estimated that thousands of people have downloaded the infected torrent files.
Not A Hat—Hit by an OS X exploit: "My copy of the iWork 09 trial installer contained a trojan.
This copy was passed to me through multiple hands. If I'd done the smart thing, and got my copy straight from Apple, I wouldn't have had this problem."
