Actually, the content string in the rule is just semantics at this point.
The problem was that my other rules were being triggered first, so I moved
this to the top of the ruleset, and everything's fine.

Thanks for your help.







Sincerely,

Brad T.

For what it's worth, I saw 113,281 WEB-IIS cmd.exe accesses yesterday.


I should have said "the only active Code Red out there at the moment."
Yours would be Nimda, and possibly a few Sadmind and manual attempts.  The
original poster was only asking about Code Red, but Nimda is certainly
worth mentioning in this context.  Sorry for the omission.
