UA-Tester

Ua-tester – A tool for User Agent WAF,IDS/IPS, Redirection testing

UA-tester is a tool to check whether a website provides different pages for different user agents like for mobile, desktop bots etc. Well this tool also delivers a lot of information. It is basically a python script which runs through various user-agents on a specified site. It also tries various options like setting cookie, redirection, URL-stability(whether the URL expires or not) an a lot more. Now I am not sure of how this might be used as a WAF-Tester. But I think, all these options & tests you perform resemble an nmap scan. You get a lot of information on response codes,redirection, static/dynamic urls used, XSS protection, server headers etc. From those, you get to know if there is a WAF at all or what the WAF is doing to prevent from scanning their website. One cool thing is the tool gets you the MD5 of the data got from a request to the site. Changes in the hash for different user-agents indicate there are separate pages.
