IIS & CGI Attacks from AOL cache sites

[Starbuck Newton <starbuck () MIAMIHEARTRESEARCH ORG>]

Hello all,

Was curious if anyone else has noticed IIS Unicode or Web-CGI attacks
originating from AOL in the last week.  We have logged attempts from:
152.163.188.162
205.188.208.199
205.188.209.5

These all resolve to cache-????.proxy.aol.com hosts.

Could these perhaps be false positives caused by bots crawling our web
site???  (We're using Snort v1.7)

Thanks in advance for any commentary.
