Short description

Win32/AutoRun.Delf.PJ is a worm that spreads via removable media.

Installation

When executed, the worm copies itself into the following location:

  • %programfiles%\­Common Files\­Systesm.exe

In order to be executed on system start, the worm sets the following Registry entry:

  • [HKEY_LOCAL_MACHINE\­SOFTWARE\­Microsoft\­Windows\­CurrentVersion\­Policies\­Explorer\­Run]
    • "Systesm" = "%programfiles%\­Common Files\­Systesm.exe"

The following file is dropped into the %systemroot%\Fonts folder:

  • %variable1%.fon (35328 B, Win32/AutoRun.AntiAV.R worm).

The worm executes the following command:

  • %systemroot%\­System32\­Rundll32.exe "%systemroot%\­Fonts\­%variable1%.fon",MyLove

The following file is dropped into the %temp% folder:

  • ~%variable2%.tmp (8256 B, Win32/TrojanDownloader.Perkesh.A trojan).

The worm registers file as a system service.


The following Registry entries are set:

  • [HKEY_LOCAL_MACHINE\­SYSTEM\­CurrentControlSet\­services\­%variable2%]
    • "DisplayName" = "%variable2%"
    • "ErrorControl" = 0
    • "ImagePath" = "%temp%\­~%variable2%.tmp"
    • "Start" = 3
    • "Type" = 1

A string with variable content is used instead of %variable1-2% .


The worm runs the following applications:

  • %variable2%

The worm attempts to delete the following files:

  • %systemroot%\­Fonts\­%variable1%.fon
  • %temp%\­~%variable2%.tmp
Spreading

The worm copies itself into the root folders of fixed and/or removable drives using the following name:

  • Systesm.exe.

The following file is dropped in the same folder:

  • AutoRun.inf

The AUTORUN.INF file contains the path to the malware executable.


Thus, the worm ensures it is started each time infected media is inserted into the computer.


The file(s) may have the System (S) and Hidden (H) attributes present in attempt to hide the file in Windows Explorer.

Information stealing

The worm collects the following information:

  • operating system version
  • MAC address

The worm attempts to send gathered information to a remote machine.

Other information

The worm terminates its execution if it detects that it's running in a specific virtual environment.


The worm quits immediately if it detects a window containing one of the following strings in its title:

  • Winsock
  • SmartSniff
  • NetXray
  • Sniffer
  • MiniSniffer
  • Sniffer Pro
