More Information
W32/Agobot-UE is a worm and IRC backdoor Trojan for the Windows platform.
W32/Agobot-UE 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.
W32/Agobot-UE spreads to other network computers by exploiting common buffer overflow vulnerabilities, including: LSASS (MS04-011), WKS (MS03-049) (CAN-2003-0812), PNP (MS05-039), RPC-DCOM (MS04-012), RPC-DCOM (MS04-012), IIS5SSL (MS04-011) (CAN-2003-0719), UPNP (MS01-059), Veritas (CAN-2004-1172), Dameware (CAN-2003-1030), PNP (MS05-039), ASN.1 (MS04-007) and by copying itself to network shares protected by weak passwords and using MSSQL servers protected with weak passwords.
The following patches for the operating system vulnerabilities exploited by W32/Agobot-UE can be obtained from the Microsoft website:
MS04-011
MS03-049
MS05-039
MS04-012
MS01-059
MS05-039
MS04-007
When first run W32/Agobot-UE copies itself to <System>\wuinit.exe.
The following registry entries are created to run wuinit.exe on startup:
HKLM\SOFTWARE\Microsoft\Windows\CurrentVersion\Run
Microsoft Update 32
wuinit.exe
HKLM\SOFTWARE\Microsoft\Windows\CurrentVersion\RunServices
Microsoft Update 32
wuinit.exe
