Apple Addresses 'Mac Defender' Threat With Security Update 2011-003 for Snow Leopard

macdefender
Apple today released Security Update 2011-003 (Snow Leopard), a new software update that addresses the "Mac Defender" malware that has been afflicting Mac users over the past month.

- Malware removal

Available for: Mac OS X v10.6.7, Mac OS X Server v10.6.7

Impact: Remove the MacDefender malware if detected

Description: The installation process for this update will search for and remove known variants of the MacDefender malware. If a known variant was detected and removed, the user will be notified via an alert after the update is installed.

The update weighs in at 2.36 MB and requires Mac OS X 10.6.7.

Seed notes for the most recent developer build of Mac OS X 10.6.8 had indicated that the update will identify and remove known variants of Mac Defender, but Apple apparently wanted to push the anti-malware portions of the update as quickly as possible before incorporating it directly into Mac OS X 10.6.8 for future updaters.

While i dont know the actual threat of his particular 'malware', I think apple needs to do a lot better than this in future. Such hot fixes need to be available within a couple of days max. If i wanted to use a virus/malware prone PC for weeks, i'd have simply opted for a windows machine instead of the mac!

And it should be available for 10.5 as well.

Apple have just made the very sensible step of allowing auto-updating of their malware definitions list. Future malware shouldn't require a formal Software Update:

"File Quarantine

Available for: Mac OS X v10.6.7, Mac OS X Server v10.6.7

Impact: Automatically update the known malware definitions

Description: The system will check daily for updates to the File Quarantine malware definition list. An opt-out capability is provided via the "Automatically update safe downloads list" checkbox in Security Preferences. Additional information is available in this Knowledge Base article: http://support.apple.com/kb/HT4651"

Nope. Just Windows ME.

It's not that you find viruses on Windows ME computers. It's that Windows ME IS a virus.

There are exploits for mac os x, linux and windows. It's just a gamble, and you might get hacked in either systems. If the mac user base continues to grow we should expect more malware.

The best protection is to be smart, and be careful to with the sites you visit.
