New Trojan Horse targets Macs

From Macworld
Security research company Intego issued a security alert about a new Trojan Horse called OSX.RSPlug.A that specifically targets Mac users. The Trojan is a form of DNSChanger that changes the Mac’s Domain Name Server (DNS) address.

According to Intego, the Trojan has been found on several pornographic Web sites. When trying to view a movie, the user is told that “Quicktime Player is unable to play movie file. Please click here to download new version of codec.”

When the user clicks the link a disk image (.dmg) is downloaded to the desktop. When the user installs the software, they are actually installing the Trojan, not a free video codec. The Trojan is installed with full root privileges, which means it has access to all files and commands on the system.
