    Wrong!
    What is happening is the worm always hits port 80 if it hits port 80 (
    regardless if its apache or iis... its port 80 ) it then drops the buffer
    overflow code on it.
    I have seen 4800 attacks on 3 class c's so far I am about to hook in a
    few more sensors all night.

    The worm attacks a random ip on port 80 if the port is closed you see
    this:

    Jul 19 19:04:49 ephesians snort: IDS3/scan_Traceroute
    TCP: 199.103.224.4:3183 ->
     216.84.196.110:80
    Jul 19 19:04:49 ephesians snort: IDS3/scan_Traceroute
    TCP: 199.103.224.4:3183 ->
     216.84.196.110:80

    If port 80 is open you will then see this:

    Jul 19 17:59:52 ephesians/216.84.194.200 snort: IDS552/web-iis_IIS ISAPI
    Overflo
    w ida: 203.69.169.4:2218 -> 216.84.194.3:80
    Jul 19 17:59:52 ephesians/216.84.194.200 snort: IDS552/web-iis_IIS ISAPI
    Overflow ida: 203.69.169.4:2218 -> 216.84.194.3:80

    Also to add this is crashing novell bordermanager servers, cisco ios (
    with web administration enabled etc etc... )

    Hope this helps someone.
