W32.Dinkdink.Worm is a worm that exploits the DCOM RPC vulnerability (described in Microsoft Security Bulletin MS03-026
) using TCP port 135. The worm targets only Windows 2000 and Windows XP machines. While Windows NT and Windows 2003 Server machines are vulnerable to the aforementioned exploit if it is not properly patched, the worm is not coded to replicate to those systems.
W32.Dinkdink.Worm uses a two-step procedure to spread itself, using a fixed server from which to download itself. As of this writing, this server does not appear to contain a copy of the worm, it does therefore appear that the worm will no longer spread.
