Craig, I don't know it it helps, but..... forcedos.exe - Runs programs in MSDOS mode I think you are right, it probably was renamed. ************************************************** Wayne S.

Hi all, on a box recently moved to a managed network rack (GX networks), over the last 2 weeks we have noticed strange behaviour. One of the box's on the subnet has been maxing out the link's bandwidth, on further investigation, massive activity was found on ports 63501, 63502, 1734 and other high range ports. The behaviour was at least 8 hours of fully limiting output, and then up to 8 hours of normal level operation and then a return to full output. at least ever 3 cycles, there would be a upload to the server at a limit of abt 512kbps. using a sniffer (netprobe) the ports were identified, and using fport these were all linked to a executable called forcdos.exe. i have searched all search engines, and have seen not one single link, so i'm assuming it's something else renamed. The files has been placed in C:\winnt\system32\msagent\local\com1\server directory. We are assuming at this time it has come in via some SQL exploit. it look's as a full backdoor access has been achieved. Due to the non-local nature of the box, and the com1 directory name, we have crrently been unable to access the directory to retrieve the exe file. The box has been locked down with the windows inbuilt firewall, locking all tcpip ports not needed. the exe is still running within the computer, but is currently unable to get out of the box. Firstly does anyone have any advice on how to get to this exe file? I dont want to just posix rd it, as i want to see the file first, and secondly does anyone have any idea what this could be? DOS or Warez? many thanks for any advice. if anyone can suggest how to get to the file, we will make it available for analysis. ----------- Craig Broad --------------------------------------------------------------------------- ---------------------------------------------------------------------------- --------------------------------------------------------------------------- ----------------------------------------------------------------------------
