Apple Updates 'XProtect' Anti-Malware Definitions to Block iWorm Threat

Apple has updated its XProtect anti-malware system to block two variants of the iWorm threat we reported on yesterday, reports MacRumors.

The complex malicious program known as Mac.BackDoor.iWorm has already infected over 18,500 Macs which can now be used by criminals to carry out various instructions.

The updated "XProtect" plist now lists OSX.iWorm.A and OSX.iWorm.B as threats preventing them from being installed. OS X typically checks for updates to XProtect on a daily basis so most users should already be protected.


More details on the malware and how it works can be found here.
