Re: Strange activity in IIS logs

["Craig Janssen" <cjanssen () mail millikin edu>]

There were some references to Code Red that I found, but that's probably due to the AAAAAAAAAAAAAAAAAA string.  I have 
never seen a virus that used the SEARCH http command in conjunction with an overlong string, such as what this one 
apparently uses.

I'm pretty sure this is a virus of some kind, I was just curious if anyone else had run into this before.  I didn't 
experience any problems with the server following this activity, so whatever it's trying to exploit it's obviously 
patched against it.

Ok, but what have you come up with?  Maybe some of the indefinite stuff will give a clue.  Have you tried BugTraq or 
VulnDev?

Interesting.  Doesn't look anything like Nimda...but does look a little like CR.
