Re: Need help to find web server attacks signature

["Maxime Ducharme" <maxime () pandore-design com>]

I'm currently seeing this scenario :

1. the person get on the web site with his browser (ie6 on xp)
we see some valid GETs at the beginning

2. the person ran one of these tools :
    Nikto : http://www.cirt.net/code/nikto.shtml
    Whisker : http://sourceforge.net/projects/whisker/
    N-Stealth : http://www.nstalker.com/nstealth/
    Retina:  http://www.eeye.com/html/Products/Retina/
   another...

3. The person retry the website to get some URLs
we see some other valid GETs further

4. the person either ran another tools on specific URLs like
Paul just said



The source IP isnt listed in DShield or mynetwatchman

The server doesnt show any weird behavior, neither have
weird traffic going on

We are thinking URLScan did a good job :)

Thanks all for your replies
