Macintosh Java malware has mutated!


Over the last few weeks we’ve read that hundreds of thousands of Apple Macintosh computers running OSX have become infected with the Flashback trojan, which is a type of virus that could, through a hole in Java security, infect your Mac and connect it to a botnet of over half a million other Macs.

And we’ve also read that Apple has released updates to fix the security problem and clean up any infected computers.

The problem is, the Flashback.s malware is pretty tricky and, it seems, is able to hide from Apple’s latest fix:

“On Monday, however, researchers at Intego, another computer security firm, discovered that a new variant of the malware, called Flashback.S, continued to spread through the same Java vulnerability. Security researchers said the variant was “actively being distributed in the wild” and noted that the malware deletes traces of itself on victims’ machines to avoid detection.
The original Flashback variant used infected computers for click fraud, in which clicks on a Web advertisement are manipulated in exchange for kickbacks. Intego researchers did not say what the new variant of Flashback is being used for. But as with all malware, its creators can choose to use infected computers however they like.”

So, what’s a body to do?
