Tor Related Vulnerabilities
Some of my research into Tor vulnerabilities:
A collection of tests that attempt to circumvent Torbutton
protections. These are useful for developers wanting to test
changes to Torbutton and investigate new attack techniques.
Vidalia Bundle - Insecure Privoxy Configuration:
versions of the Vidalia Bundle prior to 0.1.2.18 install
Privoxy with an insecure default configuration file. By
utilizing common web-browser vulernabilities, the insecure
configuration could be exploited to attack Privoxy and block, redirect or
disable filtering of requests.
Attacking the Tor Control Port with Java: an
examination of how Java (via LiveConnect) can be used to
attack the Tor control port if no authentication is used.
port vulnerability: the original control port
vulnerability that was the toast of BlackHat/Defcon 2007.
I got hacked by Tor: a discussion of how I got "hacked"
when using Tor. Nothing bad happened to me, but it did to
some other people.
Tor Hacking Utilities
Some crude Tor hacking utilities that I've put together. These are
for hacking via Tor, not hacking Tor itself.
