Filenames aren't going to do you a bit of good. Nowadays they're as individualized as human beings. It's unfortunate that you deleted them, because it will make it next to impossible to find out what they were.Came in this morning to find a windows 2003 server I manage scanning the Internet for machines listening on tcp 139 and 445. While looking at the machine I noticed the following processes running. Mwvsta.exe found in c:\windows\system32 rundll16.exe c:\windows\system23 Ponoas.exe c:\windows\system32 I believe that the ponoas.exe is some sort of rootkit although searching on google for this file name returns nothing. Also searching mwvsta.exereturns nothing. At this point I have removed these files from the system and registry but am weary that the server will get hit again. Has anyone had an experience with the following file or have any idea what rookkit of virus they are associated with?
When you say you noticed the following processes running, how did you notice them? Were they visible in Task Manager? Or did you use some other tool to "see" them?
Do you have any idea how the breakin occurred?Is there a firewall between this host and the internet? Any intrusion detection equipment? Any traffic-tracking software?
