Technical Details

This malware is distributed in a RAR archive file attached to an e-mail message.

The archive file contains an executable file which may be detected as either Gen:Trojan.Heur.RP.Mq0@ayDoNAeb or Trojan.Win32.AntiAV.iup.

Installation

The executable file uses the icon of a Microsoft Word document to appear legitimate. On execution, the malware will drop a clean Word document and open it for viewing, to further deceive the user.

Meanwhile, the malware will create a registry launchpoint so that subsequently its file will be automatically run at every Windows startup:

  • HKLM\Software\Microsoft\Windows\CurrentVersion\Run common = (path of the malware)
Network connections

Once its file is active, the malware will attempt to connect to:

  • tokyonews.edns.biz
  • tokyoIP.freewww.info

The malware may also send information to an external party by a POST to an info.php page on a remote server.
