In this article “More than 600,000 Macs have been infected with a new version of the Flashback Trojan horse that’s being installed on people’s computers with the help of Java exploits, security researchers from Russian antivirus vendor Doctor Web said on Wednesday.

Flashback is a family of Mac OS malware that appeared in September 2011. Older Flashback versions relied on social engineering tricks to infect computers, but the latest variants are distributed via Java exploits that don’t require user interaction.

On Tuesday, Apple released a Java update in order to address a critical vulnerability that’s being exploited to infect Mac computers with the Flashback Trojan horse.

… Over 300,000 of the Flashback-infected Macs, or 56% of the total, are located in United States, while over 100,000 are located in Canada, Doctor Web said. The U.K. and Australia are next, with 68,000 and 32,000 infected Macs, respectively.”
