Macs Do Have a Virus Problem -- 600,000 Botnet Infections Discovered

By Gary Cutlack on at

Russian security experts are claiming to have discovered a massive Mac-based botnet ring, which is believed to consist of around 600,000 infected computers running OS X.

The trojan, which is rather unfortunately known as Backdoor.Flashback.39, managed to infect Macs by redirecting their owners to hacked sites and loading an exploited Java applet. The security firm says it believes 4million compromised sites are listed in Google's search results, waiting for a Mac user to appear for infection.

The majority of hacked Macs are residing in the US and Canada, with 274 infections spotted in Apple's home turf of Cupertino, California. Apple's since released a security patch to block the Java hole. [Dr Webb via The Inquirer]
