Technical Details

Trojan:OSX/Zweite.A masquerades as a Safari application.

There are two 'variations' of the trojan: one for Intel Macs and the other for PPC Macs. It also comes with a configurator component for both OS X (Intel) and Windows. The configurator components are detected as Trojan:OSX/Zweite.A and Trojan:W32/Zweite.A respectively.

The malware author claims this trojan is his second OSX malware (hence where the name Zweite, which is German for 'second').

Activity

Upon execution, the trojan will attempt to perform a number of actions, which are specified by a text file named 'config.txt'. These actions may be any the following:

  • Take a picture from Webcam using isightcapture
  • Shut down the system
  • Display a dialogue that asks for the admin password and stores it in a file
  • Execute a command or script
