    :
    : While clearing out some information in our web filter I noticed some odd
    : traffic: internal web server addresses showing up under different dns
    names.
    : For instance in the Host Name field we see "sucks.freexxxxxvideo.com" and
    : yet the IP comes up in our address range. Opening the traffic I find a DSL
    : customer's IP from speakeasy.net. It looks like they are making what
    starts
    : out as a legitimate request from our IIS 5.0 webserver and then redirect
    to
    : whatever porn site they are after at the time.
    :
    : Looking at the IIS logs on the affected server I see nothing more than
    this
    : to give me a clue:
    :
    : 2003-11-05 12:44:26 66.93.24.88 - X.X.X.X 80 GET /Default.asp - 200
    : sucks.freexxxxxvideo.com Mozilla/4.0 -
    :
    : Is this a common occurrence with IIS? How do we stop this from happening?
    :
    : Thanks for any help.
