IRC backdoor trojan.

I've tracked a trojan on my server after I noticed some warez being uploaded in an upload folder + they removed a couple of maps in order to create space for their own stuff.

The trojan works as a backdoor and opens a port. Then it runs an ftp like server that enables the user to delete, create and upload/download files and maps. At the same time it tries to connect to irc as a bot.

I have their irc channel  and I can see other hacked servers in there. Is there anyway some higher authorities can be informed of this? If possible i would like the ''hackers'' to be tracked down and possibly prosecuted..

A note: C:\WIN\system32\rpcxserv.exe  is the backdoor trojan file and is run as a service listed under RPC Interface. When I try to find this file it simply doesn't exist, but It does run and does open the port again after enabling the service.

I've set view all hidden files etc in the map options of windows 2003. Is there anyway this file can be deleted? I've searched google, but non of the virus scanning companies list this file, nor does norton corporate antivirus find this trojan. I've seen around three other cases of infected servers on google, but they didn't mention any of this that could help me out.

For now I've just disabled the service, and the open port is gone...but i do want to delete these malicious files.

I don't think the local police could do anything here. They lifted their shoulders when a bike of 2000 euro was stolen from my hallway, although there were rules to investigate a theft if the item was stolen from an enclosed area .

But anyways...I'll inform and see if they have something for internet crimes.

Any advice on those hidden files is welcome.

Be glad you can't find it . It boots the ftp and creates the open port. I don't know how this ended up on the server. Might have been software, or the internet itself.

I managed to delete it by using the search option of windows explorer. I didn't know it doesn't search for hidden files by default, although i've set map options to include hidden files. Bit confusing.

Other part of the trojan where you can actually see some server logs and the irc channel.
