Zlob Trojan

Viruses
A common misconception among Mac users is that Mac OS is immune to viruses. Unfortunately viruses do exist for Mac OS though they are few in number. Below is a list of some of the most commonly found Mac Viruses over the past several years.

In 2006 there was a Trojan worm discovered known as OSX/LEAP that used iChat as its method of transfer. If an infected computer would iChat a friend a message would show up on the friends computer claiming to have pictures of then-upcoming OS X Leopard. Once the message was opened and downloaded the Trojan worm infected any recently opened application with malicious code rendering them useless.

In 2007 three Zlob Trojan viruses known as OSX/DNSChanger, OSX/RSPlug, and OSX/Jahlav crossed over from Windows to Mac OS. The Mac OS versions had the same objective as the original Windows worms which was to alter the users DNS and direct its traffic to malicious websites by posing as a needed video codec to access internet pornography.

In 2008 F-Secure discovered Mac's first malicious cleaning tool called MacSweeper. It mimicked a then-legitimate cleaning tool name Mac Sweeper and claimed to find problems in the users system and then asked for payment to fix the problems.

In 2009 a backdoor spyware named OSX/KROWI infected computers through pirated versions of iWork 2009 and Adobe Photoshop. Once on the users computer it connected to a remote network allowing others to enter the computer without authentication.

In 2011 Intengo discovered a OSX/FLASHBACK, a malware that uses Java vulnerabilities to enter a user's computer and harvest user information. The most common package of FLASHBACK was in a malicious Adobe Flash installer but there are newer packages that are disguised as a software update.
