Trojan Found in Pirated Copies of Adobe Photoshop CS4 for Mac

Mac users downloading copies via BitTorrent tracker sites get hit with another malware attack. Just yesterday I reported on how Mac users, who have prided themselves for years that it was their PC cousins bearing the brunt of virus and malware attacks, were being infected by a Trojan horse contained in pirated copies of Apple's iWork '09 downloaded from public BitTorrent tracker sites.
