For the third time in two weeks Apple has released an update to Java for Mac to combat the Flashback Trojan that has infected millions of Macs around the world. The latest update, 2012-003 was release just a bit ago and is available via Software Update.
The 66MB update removes “most common variants of the Flashback malware” and also disables automatic execution of Java applets in Java Web. This should make your Mac safe against this trojan – at least until another variant comes out.
The Flashback trojan is a reminder that even though us Mac users have by-and-large been able to run for years antivirus free, those days may be over. Mac adoption has made OS X a target rich environment for those who create and distribute malware, a problem that owners didn’t have when there was only 5% marketshare for Macs. There are plenty of good reliable solutions out there including some in the Mac App Store.
If you haven’t run Software Update today be sure to do so.
