Apple Counters PDF Trojan Threat with Malware Definition Update

Cupertino based technology powerhouse Apple has released a new security update, updating its malware definition, aimed at protecting Mac users from a new, emerging Trojan threat, according to new reports.

The mentioned threat - a Chinese Trojan, was first discovered almost a couple of months back in July - however it was not functional back then. But, as the Trojan started becoming semi functional, Apple, as it seems, did not want to take any risks and tackled the issue immediately by introducing this new malware definition.

With this move, any unsuspecting Mac OS X user, who clicks on the malware to open it, will be alerted immediately as the file containing malicious components.

According to security experts, users have no reason to panic now though, as the Trojan is yet to become fully functional.

The malware application comes in two separate segments. One - “OSX/Revir.A”, which is basically aimed at diverting the victim’s attention by opening a PDF file, named “Offensive Political Statement”, while the second and more dangerous one is the “OSX/Imuler.A”, which opens up a backdoor to the infected system, thus leaving it vulnerable for unauthorized access.
