Security researchers recently discovered a new backdoor Trojan for Mac OS X, called OSX/Tsunami-A.

"What makes Tsunami particularly interesting is that it appears to be a port of Troj/Kaiten, a Linux backdoor Trojan horse that once it has embedded itself on a computer system listens to an IRC channel for further instructions," writes Sophos' Graham Cluley.

"Typically code like this is used to rally compromised computers into a DDoS (distributed denial-of-service) attack, flooding a website with traffic," Cluley writes. "If you were wondering where the name 'Tsunami' comes from, that should probably help explain things."
