Although, Apple's Mac had been the target of major malwares as a result of its growing popularity, this current attack is perhaps the largest so far.
Apple, however, has declined to comment on the latest findings, but hinted that a patch will follow in the upcoming version of the OS due this summer.
Also, the company revealed a future plan to tackle such security threats by a feature it called Gatekeeper, billed to be introduced in the next version. The tool will among other things ensure that developers register with Apple, and users have the option to keep their computers from installing software that has not been duly registered.
