I wouldn't consider this any new type of attack. There are simple perl scripts that have been available for years now that will alert on this kind of activity. Simply execute the script with the host IP you'd like to scan and it goes to town checking for all known cgi, frontpage, iis, apache, etc, vulnerabilities. Now, a lot of alerts I recieve from snort are what I consider Internet drive-by's. SQL service scans, codes red, etc.. This scan you received I feel is specific-- you were directly targeted and should raise your awareness to a new level when investigating other suspicious activity. -havoc. ----- Original Message ----- From: "opus" <opusat_private> To: <Incidentsat_private> Sent: Friday, October 25, 2002 11:47 AM Subject: Strange attacks > Beginning on October 10th at 1:42am CDT what was considered a pretty > significant attack took place.
