Worm:Win32/Wukill.AM is a computer worm. This means that the threat can propagate by itself and crawl on every computer using various tactics and deployment schemes. It is able to run the malicious code on every Windows start-up due to the modification of registry entries and adding its own value to run on the boot-up process.

Worm:Win32/Wukill.AM can create a copy of itself on removable drives as well as network-shared resources; therefore, the threat can widely spread in a matter of time. It is important to resolve the infection as soon as possible to prevent the malware from infecting other drives and network resources.

How does it infect the computer?

Propagation of Worm:Win32/Wukill.AM is accomplished in several ways, and the fastest method is to copy the Worm to computers that are connected via a local area network (LAN). The threat also attacks removable drives such as USB flash drives or removable hard drives, where in Worm:Win32/Wukill.AM, an autorun.inf file is placed on the root drive to make sure that malicious code runs automatically each time the removable drive is connected to the computer. While on the LAN setup, simply accessing the infected drive launches Worm:Win32/Wukill.AM provided that the autorun feature is enabled.

How does this malware operate?

When executed, Worm:Win32/Wukill.AM can do the following:

  • It copies itself to the Windows system folder.
  • The worm modifies registry entries to ensure that it runs each time Windows starts.
  • Worm:Win32/Wukill.AM drops malicious files on infected drives, especially the autorun.inf file, which triggers the worm to run when users access the compromised drive.


The existence of Worm:Win32/Wukill.AM can be confirmed if the following registry entries are present:

Adds value: TempCom = “%Fonts%\{random characters}.com”
To subkey: HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Run

Adds value:  KaV—XP = “{random numbers}”
To subkey: HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Setup

It also modifies registry entries to disable Task Manager using the following value:

Adds value: “DisableTaskMgr”
With data: “1”
To subkey: HKCU\Software\Microsoft\Windows\CurrentVersion\Policies\System

Aside from the registry entries, the local antivirus program may issue a warning that the computer is infected with Worm:Win32/Wukill.AM and that removal is necessary.
