A simple websocket proxy that allows viewing of websocket requests, repeating requests and "Burp intruder" style replay attacks. Quick and dirty tool, may have plenty of bugs.
For a more detailed write-up regarding the tool, see: https://sensepost.com/blog/2015/another-intercepting-proxy/
You need to setup your Nodejs environment, in the project directory:
git clone https://github.com/sensepost/wsproxy.git
npm install
This will install all your dependencies etc.
The tool should be easy enough to use,
nodejs wsproxy.js
To view the requests, a webserver is started up on https://127.0.0.1:8082 by default, changable in config.js. To disable this webserver, change config.webserver=true to config.webserver=false in config.js. To create custom mangle rules, modify "mangle" in wsprocessor.js. Replace rules also get applied here. Replace rules can be modified in config.js or altered at runtime through the web-interface.
