Technical Details

Upon execution Acanze.A will create a hidden system file named 'login.bat' into %WINDOWS% directory. It will then set a registry key:

  • " HKLM\Software\Microsoft\Windows\CurrentVersion\Run\msnmsgr = "C:\WINNT\login.bat"

The key allows Windows to start the bat file each time a user logs on.

Under Italian versions of Windows additional files will be dropped and the attributes to both file set to hidden system.

  • " %WINDOWS%\SYSTEM\HOTPLUG.dll
  • " C:\Programmi\Windows NT\netapi.dll

The worm will then check whether a connection to an Italian site can be established. If so it will create email messages containing copy of its body and send them to recipients in Outlook's Contact list.
