The [email protected]
spreads by pretending as .exe files on the compromised PC. The pretended executable file has a damaged header that prevents the file from being opened. The original executable file is present in the attached data of the contaminated executable. When the worm is executed, it makes “%Windir%IEXPLORE1.exe”, “%System%fgb2ksudll.dll”, and “%System%up.exe”. To add up, “%Windir%” is a variable that refers to the Win installation folder. By default, it is “C:Windows” or “C:Winnt”. The worm adds the value "load" = "%Windir%IEXPLORE1.exe" to the registry key, so that it’s opened each time the Windows starts. The worm also ends the process of “EGHOST.EXE”, “MAILMON.EXE”, “KAVPFW.EXE”, and “IPARMOR.EXE”.
