More Information
W32/WarPigs-E is a worm and IRC backdoor Trojan for the Windows platform.
W32/WarPigs-E spreads to other network computers infected with Troj/NetDevil and to other network computers by exploiting common buffer overflow vulnerabilities, including PNP (MS05-039).
W32/WarPigs-E runs continuously in the background, providing a backdoor server which allows a remote intruder to gain access and control over the computer via IRC channels.
When first run W32/WarPigs-E copies itself to <System>\reaIplayer.exe.
The following registry entries are created to run reaIplayer.exe on startup:
HKCU\Software\Microsoft\Windows\CurrentVersion\RunOnce
atidriver
reaIplayer.exe
HKLM\SOFTWARE\Microsoft\Windows\CurrentVersion\Run
atidriver
reaIplayer.exe
The following registry entry is changed to run reaIplayer.exe on startup:
HKLM\SOFTWARE\Microsoft\Windows NT\CurrentVersion\Winlogon
Shell
explorer.exe reaIplayer.exe
(the default value for this registry entry is "Explorer.exe" which causes the Microsoft file <Windows>\Explorer.exe to be run on startup).
Registry entries are created under:
HKLM\SOFTWARE\Microsoft\MS. update\
