Re: [tor-talk] Regarding the Hacking Team leak and the "TOR interception" (all uppercase Tor obviously)



The browser would send a socks5 connect request to the hacking team
proxy server, which would connect to the real hidden service and
transparently proxy the content to the browser. If the hidden service
had an SSL connection (like facebook hs), it would try to MITM with the
installed cert.
The infected client would have to use internet explorer or chrome, setup
for tor usage.
