More Information
W32/Rbot-GOS is a worm with IRC backdoor functionality for the Windows platform.
W32/Rbot-GOS 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/Rbot-GOS spreads to other network computers:
- by exploiting common buffer overflow vulnerabilities, including: LSASS (MS04-011), SRVSVC (MS06-040), RPC-DCOM (MS04-012), PNP (MS05-039), ASN.1 (MS04-007), RealVNC (CVE-2006-2369) and Symantec (SYM06-010)
- networks protected by weak passwords
When first run W32/Rbot-GOS copies itself to <System>\netsrv.exe. The following registry entries are created to run W32/Rbot-GOS on startup:
HKCU\Software\Microsoft\Windows\CurrentVersion\Run
Microsoft
netsrv.exe
HKLM\SOFTWARE\Microsoft\Windows\CurrentVersion\RunServices
Microsoft
netsrv.exe
HKLM\SOFTWARE\Microsoft\Windows\CurrentVersion\Run
