Botnet goes on Mac attack

week in review Long thought of as safer than its competition, Apple's Mac platform is battling a nasty piece of malware designed to steal users' personal information.

More than 600,000 Macs worldwide are infected with the Flashback Trojan, according to Russian antivirus company Dr. Web. The malware was initially found in September 2011 masquerading as a fake Adobe Flash Player plug-in installer, but in the past few months it has evolved to exploiting Java vulnerabilities to target Mac systems.

Simply visiting a malicious Web site containing Flashback on an OS X system with Java installed can result in an infection. Once installed, the Flashback will inject code into Web browsers and other applications like Skype to harvest passwords and other information from those program's users.
