Apple's popular, long-running "I'm a Mac, I'm a PC" ad campaign, pitting the oh-so-cool Mac dude against the chunky, nerdy PC guy, aimed to convince consumers that Macs are, among other things, more secure than those stereotypically virus-prone Windows PCs. Now a variant of a popular Windows-based Trojan targeting Mac OS X has emerged, demonstrating that Macs and Windows are quite susceptible to the same sort of threats.
According to security company Sophos, the Trojan is a variant of a Windows-based RAT (remote access Trojan) called darkComet. The company has dubbed the malware OSX/MusMinim-A, or MusMinim for short; the Trojan refers to itself as "BlackHole RAT," however.
It's very basic, per Sophos, and can be eradicated with up-to-date antivirus software. Still, it serves as a necessary reminder that no platform is immune to malware. As Apple's platform gain popularity, its "security through obscurity" defense becomes less reliable.
Among the Trojan's tricks, it opens a full-screen window from which a user has only one option: to click a Reboot button. The window includes a text message whose opening words -- intentionally or otherwise -- invokes Apple's infamous "I'm a Mac" ad campaign:
I am a Trojan Horse, so i have infected your Mac Computer. 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.
According to Sophos, the Trojan, still a work in progress, has other disruptive functions: placing text files on the desktop; sending restart, shutdown, and sleep commands; running arbitrary shell commands; sending URLs to a client to open a website; and opening a fake Administrator Password window for phishing purposes.
