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

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:
