In-Reply-To: <m38y86m1gw.fsf@pixie.isrnet> Rodrigo,
My question is, what do you think is the best procedure to track down the executables responsible for this behavior?
Well, you have packet captures of the activity, showing the source ports on the infected systems. Go to each, and run tlist.exe (from the MS Debugging Tools) and 'netstat -ano' (note: '-o' switch is NOT available on Win2K) to get the PID and path of the process using the port. You can also run openports.exe (from DiamondCS) or portqry.exe v2 (from MS) to get the process-to-port mapping (fport.exe has the limitation of requiring an administrator login). These baddies may have written entries in any of the AutoStart locations, so using autoruns.exe (from SysInternals) or the Silent Runners.vbs script will get the necessary information for you. Good luck. If you have any questions, let me know. H. Carvey "Windows Forensics and Incident Recovery" http://www.windows-ir.com http://windowsir.blogspot.com
