Re: CodeRed II Mutants - not

My iis5.0 (patched) logs show the length of the original CodeRed II worm as 3818.

It's the same Code Red II.

The overall request is usually 3818 bytes, but this is 3379 bytes of payload
plus whatever headers are used:

        GET /default.ida?XXXXXXXXXXXXXXXXXXXXXXX....
        Content-type: text/xml
        Content-length: 3379

        {{3379 bytes of binary data here}}

I routinely find other headers too, such as:

        GET /default.ida?XXXXXXXXXXXXXXXXXXXXXXX....
        Host: 64.170.162.100
        Connection: keep-alive
        Content-type: text/xml
        Content-length: 3379 
        Via: 1.0 ampere (NetCache NetApp/5.0.1R2)
        X-Forwarded-For: 212.198.146.153

        {{3379 bytes of same binary data here}}

Same great taste, just a bit more filling.

No evidence *whatsoever* of any Code Red II variants.
