Apple erases emerging Mac OS X trojan via malware definition update
Chinese malware targeting Mac users wasn't actually functional, but Apple has squashed the exploit anyway by delivering a malware definition update that flags the Trojan Horse as being malicious when users try to open it.
New malicious software reported by CNET this week has been added to Mac OS X's internal blacklist of known malware, erasing the threat even before its authors were able to get it to the point of actually functioning.
The described "Trojan-Dropper:OSX/Revir.A" was not yet functional, according to security software vendor F-Secure. However, a report by MacRumors confirms that Apple has already distributed a new definition, which lets the operating system identify and warn users before they attempt to open it.
