Security software maker Sophos has discovered a new type of backdoor trojan virus that affects Apple's Mac OS X platform.
In a blog post, the company explained that the OSX/MusMinim-A is a variant of the Remote Access Trojan (RAT) for Windows known as darkComet.
The company said that the creator of the original darkComet for Windows contacted Sophos and told them that there was no association between the two trojans but he was working on his own RAT trojan for Mac.
The unidentified maker of the trojan calls the virus BlackHole RAT. The virus it self informs the user about its existence on an infected computer and tells them the trojan is still in beta, with more devastating functions to be added later.
“I know, most people think Macs can't be infected, but look, you ARE Infected! I have full controll over your Computer and i can do everything I want, and you can do nothing to prevent it. So, Im a very new Virus, under Development, so there will be much more functions when im finished,” the virus notification pop-up reads.
The company said that the trojan is capable of pasting text files on the desktop, sending a restart, shutdown or sleep command to the computer and placing a notification on the system that only lets users restart the system.
