More Information
W32/Sdbot-AFO is a worm with backdoor functionality for the Windows platform.
W32/Sdbot-AFO 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), Veritas (CAN-2004-1172), MSSQL (MS02-039) (CAN-2002-0649), PNP (MS05-039) and ASN.1 (MS04-007).
W32/Sdbot-AFO also spreads via network shares and MSSQL by searching for weak passwords, and can also spread via instant messaging programs.
W32/Sdbot-AFO 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/Sdbot-AFO copies itself to <Windows system folder>\javams64.exe.
The following registry entries are created to run javams64.exe on startup:
HKLM\SOFTWARE\Microsoft\Windows\CurrentVersion\Run
Service Monitor
javams64.exe
HKLM\SOFTWARE\Microsoft\Windows\CurrentVersion\RunServices
Service Monitor
javams64.exe
The following registry entry is set:
HKCU\Software\Microsoft\OLE
Service Monitor
javams64.exe
