Technical Description:

The malware consists of a packed executable with the size of approximately 27 Kb. It performs the following action once launched in execution:

  • Lowers the security settings on the Internet Zone for Internet Explorer.
  • Creates a new dial-up connection with a premium number.
  • If a modem is attached to the computer, tries to dial the given number
  • Opens in Internet Explorer a link hard coded in the malware's body. This opens up the way for further infections given the fact that the security settings for Internet Explorer were previously lowered.
