A client on your network has somehow had a gator adware/spyware client
installed on its host.
This rule should detect
Many corporations and individuals view this type of adware/user profile
software a policy violation by their end users. This type of software is
also generally thought of as 'spy-ware' by the way sends data about your
surfing habits to a third party without the direct knowledge of the end
x.1.20.23 - - [ 7/Jun/2003:22:34:07 -0500] "POST
HTTP/1.1" - - "-" "Gator/4.0"
This particular rule looks at the gator client's POST to a url with the
uricontent containing bannerserver.dll coupled with the Gator/4.0 client
windows based operating systems.
A website tricks the end user into loading this software, or this software
can be coupled with other software installing itself silently on your
computer without the end users knowledge.
Ease of Attack:
The esiest way to clean up this software is to download a copy of
pestpatrol from pestpatrol.com.
To eliviate further installation you should tighten up the security level
on your browser and watch what software you install.
