More Information

W32/Rbot-DVF is a worm for the Windows platform.

W32/Rbot-DVF spreads to other network computers by exploiting common buffer overflow vulnerabilities, including: LSASS (MS04-011), RPC-DCOM (MS04-012) and WKS (MS03-049) (CAN-2003-0812) and by copying itself to network shares protected by weak passwords.

When first run W32/Rbot-DVF copies itself to <System>\usaplug.exe.

The following registry entries are created to run usaplug.exe on startup:
