Whether you need to worry depends very much on what kind of server you're on, and whether those files exist.
I believe this is the NIMDA virus attempting to propagate. It won't work if you're running an Apache or other non-MS server. It also won't work if you've got the latest MS server patches installed.

In the past Ive tried emailing the isp's of the originating Ip address and never got a single response. I dont bothger banning the IP,s. I just continually make sure that the server is a secure and watertight as possible.
