Apple on Tuesday for the first time publicly acknowledged a malware
campaign that has infected an estimated 600,000 Macs, and said it would
release a free tool to disinfect users' machines.

"A recent version of malicious software called Flashback exploits a
security flaw in Java in order to install itself on Macs," Apple said in
a support document published Tuesday. "Apple is developing software that
will detect and remove the Flashback malware."

Although Flashback has circulated since September 2011, it was only last
month that the newest variant began infecting Macs using an exploit of a
Java bug that Oracle patched in mid-February.

Apple maintains its own version of Java for Mac OS X, and is responsible
for producing security updates. It issued a Java update on April 3 that
quashed the bug Flashback has been using to sneak onto Macs.
