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.
