Do you have a Mac? If so, has it ever been infected?

I just heard about an attack-Mac agent that was discovered this week, by researchers at Kaspersky Lab:

“The malware infects computers in one of two ways. In some cases, users receive a pop-up prompt purporting to be from Adobe Flash asking them to install an update and type in their password — hence the Trojan’s name, ‘Fakeflash’ or ‘Flashback’. But in most cases, attackers appear to have exploited a loophole in Java software that automatically downloads the malware onto victims’ machines without any prompting.

Apple issued two security patches for the Trojan this week and encouraged Mac users to run their software updates as soon as possible.”
