Sometime on Jul 19, S. Krishnan assembled some asciibets to say:
have caused any harm yet, but this has been tried over and over again.
Sure looks like one. Log the IP and complain to the ISP as well as to CAUCE.
The IP is either being spoofed or it's coming from six different places (I mean completely different - 206, 193, 194, 61, 63, 207). Also, it's been detected as the Red.ida worm, on bugtraq. All IIS versions are vulnerable, apache is not. It's most likely that these hits are coming from an infected machine, not from the originator.
