Well I made a small intercepting proxy which inserts this JS if you want to try..

Use http proxy 92.163.21.52 port 9990 and start browsing :)

I'll let the VM opened for a few hours

edit: port 9999 edit2: port 9990

(changed the port because some botnet is using it to target a website and maybe that's because I used an online proxy checker to test it)
