https://www.usenix.org/legacy/events/leet11/tech/full_papers/LeBlond.pdf Here is an interesting paper about deanonymising Tor users. It covers some deficiencies in Tor (reusing circuits) as well as some problems with the way it's used. https://en.wikipedia.org/wiki/TorChat https://en.wikipedia.org/wiki/Tor_(anonymity_network)#Tor_Browser Here are URLs about TorChat and TorBrowser which I mentioned in my talk. At the hands-on workshop I'll cover these things in more detail. -- My Main Blog http://etbe.coker.com.au/ My Documents Blog http://doc.coker.com.au/
