Apple Releases Java Update to Remove Flashback Malware

Apple just released Java for OS X 2012-003, an update to the Java implementation in OS X. The update removes "the most common variants of the Flashback malware." Interestingly the update disables the automatic execution of Java applets, and, if automatic execution is re-enabled, will again disable it if no applets have been run for "an extended period of time".

It was reported earlier this week that Apple was in the process of creating software to remove Flashback. It's been claimed that the Flashback malware infected more than 600,000 Macs at its peak, though there have been a number of programs created to quickly and easily cleanse infected machines.

This Java security update removes the most common variants of the Flashback malware.

This update also configures the Java web plug-in to disable the automatic execution of Java applets. Users may re-enable automatic execution of Java applets using the Java Preferences application. If the Java web plug-in detects that no applets have been run for an extended period of time it will again disable Java applets.

This update is recommended for all Mac users with Java installed.

For details about this update see: http://support.apple.com/kb/HT5242

The update can be downloaded via Software Update. A separate Java for Mac OS X 10.6 Update 8 is available for users on Mac OS X Snow Leopard.

This isn't a virus. And it's estimated that less than one percent of macs that had the trojan. The OS was in no way affected, it relates to third party software which is being dropped by Apple.

Troll much?

You can't honestly be stupid enough to not know the difference between a Trojan horse and a virus.

All computers are susceptible to viruses... even iOS devices. Macs don't get as many viruses because Windows is more "popular" and is used in huge corporations, where information is very valuable. Apple does try hard to keep OS X virus free though, including adding in an automatically updating safe list for some virus that was causing problems last year.

Is Flashback a virus? It's malware, but is it a self-propagating virus? And it's not true that Macs have fewer viruses because Windows is "more popular". OS X is inherently more secure, but as Flashback proves, it's not 100% bulletproof. But as Apple has proven with this update, the good design of OS X allows them to protect users, even after an incident arises.
