More Information

W32/Vanebot-AH is a worm with backdoor functionality which allows a remote intruder to gain access and control over the computer.

W32/Vanebot-AH spreads to other network computers by scanning network shares for weak passwords and by exploiting common buffer overflow vulnerabilities, including Symantec (SYM06-010).

When first run W32/Vanebot-AH copies itself to <System>\sansv.exe.

The following registry entry is created to run sansv.exe on startup:

HKLM\SOFTWARE\Microsoft\Windows\CurrentVersion\Run
SANS Service
System\sansv.exe
