I'm cc-ing this to Speakeasy only "FYI". No finger pointing intended.
The CodeRed flavored thingy that started touching my server this morning, originating mostly from Speakeasy DSL customers, has been very busy. In just 8 hours my little single-IP site has seen it 63 times from 32 unique IP's. That's many times the activity my server has seen from CRv1 and CRv2 (my grand total *ever* of the "NNNN" style probes is 128).
Again, it looks like this:
64.81.32.130 - - [04/Aug/2001:13:49:57 -0700] "GET /default.ida?XXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXX%u9090%u6858%ucbd3%u7801%u9090%u6858%ucbd3%u7801%u9090%u6858%ucbd3%u7801%u9090%u9090%u8190%u00c3%u0003%u8b00%u531b%u53ff%u0078%u0000%u00=a HTTP/1.0" 404 275 "-" "-"
Note the XXX's instead of NNN's. CRv1 and CRv2 sent N's.
The other thing that makes this look different from CRv1 and CRv2 is the limited range of IP's it's coming from, and that I'm getting multiple hits from the same IP (I've seen no repeated IP's in CRv1 and CRv2 probes):
wconrad@mars:/usr/local/apache/logs$ for h in `grep 'default\.ida?XXX' access_log | awk '{print $1}'`; do echo $h `host $h | grep Name | awk '{print $2}'`; done | sort | uniq -c

Why would someone restrict the worm to a particular range of IP's? Testing? Angry at Speakeasy? Your guess is probably better than mine.
