Apple has updated its malware definitions for OS X so as to defend Macs against a botnet that allowed a piece of malware called Mac.BackDoor.iWorm to install on systems. iWorm had made its way onto 17,000 machines by the time it was disclosed last week. Once on a user's system, the malware could install other pieces of malware, in addition to stealing sensitive data. Apple has now taken steps to protect its users from iWorm, according to MacRumors:
In an effort to address the threat, Apple has now updated its "Xprotect" anti-malware system to recognize two different variants of the iWorm malware and prevent them from being installed on users' machines.
Your machine will automatically check for updated definitions for Xprotect daily. Have you or anyone you know been impacted by this malware? Let us know in the comments.
