CHARACTERISTICS
Win32.Yenik is an Internet worm that attempts to spread via e-mail and P2P file sharing networks. It targets Kazaa, Grokster, Bearshare, eDonkey2000, eMule, Morpheus P2P sharing programs.
Method of Installation
In order to function the worm must run from the %System% directory with the name updater.exe. It uses updater.exe as a base file to create a copy which later gets base64 encoded and stored in yeni.txt.
Note: '%System%' is a variable location. The worm determines the location of the current System folder by querying the operating system. The default installation location for the System directory for Windows 2000 and NT is C:\Winnt\System32; for 95,98 and ME is C:\Windows\System; and for XP is C:\Windows\System32.
