Blade - A Webshell Connection Tool With Customized WAF Bypass Payloads

Saturday, January 2, 2016


Blade is a webshell connection tool based on console, currently under development and aims to be a choice of replacement of Chooper (中国菜刀). Chooper is a very cool webshell client with widly typies of server side scripts supported, but Chooper can only work on Windows opreation system, so this is the motivation of create another "Chooper" supporting Windows, Linux & Mac OS X. Blade is based on Python, so it allows users to modify the webshell connection payloads so that Blade can bypass some specified WAF which Chooper can not.
