More Information
W32/Rbot-AWF is a worm with IRC backdoor functionality for the Windows platform.
W32/Rbot-AWF spreads:
- to other network computers by exploiting common buffer overflow vulnerabilities, including: LSASS (MS04-011), RPC-DCOM (MS04-012), WKS (MS03-049) (CAN-2003-0812), PNP (MS05-039) and ASN.1 (MS04-007)
- by copying itself to network shares protected by weak passwords
W32/Rbot-AWF 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/Rbot-AWF copies itself to <Windows system folder>\mspatch32.exe.
The following registry entries are created to run mspatch32.exe on startup:
HKLM\SOFTWARE\Microsoft\Windows\CurrentVersion\Run
MS-patch
mspatch32.exe
HKLM\SOFTWARE\Microsoft\Windows\CurrentVersion\RunServices
MS-patch
mspatch32.exe
Registry entries are set as follows:
HKLM\SOFTWARE\Microsoft\Ole
