How governments have tried to block Tor [28C3]

How governments have tried to block Tor

Iran blocked Tor handshakes using Deep Packet Inspection (DPI) in January 2011 and September 2011. Bluecoat tested out a Tor handshake filter in Syria in June 2011. China has been harvesting and blocking IP addresses for both public Tor relays and private Tor bridges for years.

Roger Dingledine and Jacob Appelbaum will talk about how exactly these governments are doing the blocking, both in terms of what signatures they filter in Tor (and how we've gotten around the blocking in each case), and what technologies they use to deploy the filters -- including the use of Western technology to operate the surveillance and censorship infrastructure in Tunisia (Smartfilter), Syria (Bluecoat), and other countries. We'll cover what we've learned about the mindset of the censor operators (who in many cases don't want to block Tor because they use it!), and how we can measure and track the wide-scale censorship in these countries. Last, we'll explain Tor's development plans to get ahead of the address harvesting and handshake DPI arms races.

STOP Chinese commerce. They attack us constantly. LOL

[TheCentralServices]

We have introduced all these measures in our company already years ago, it was called Facebook, but our sysadmins have routed all traffic through Tor, so nobody can find our webcams through google anymore. Anonymity is only neccessary if you have got something to hide.

But that was not the whole question. We want to control the whole internet and we need a step by step tutorial how to surpass those kids from Mossad, Tunesia, China and Qatar.

A user friendly stuxnet 4.0 for iPhone would be nice.

There are several ways one could "protect" themselves from TOR, anonymity & privacy. The real question is "WHY" would anyone WANT to? LOL

[gjc82071]

Anonymity & privacy are terrible & you'd like to know how you can "protect" yourself from them? OK. Remove all curtains & blinds from your windows, disable your firewall, install video cameras in every room & stream the content online, keep a diary/blog of every thought you have & upload it, along with your social security #, passwords, PIN #s, etc. After completing that, you should be well on your way to "protecting" yourself from TOR, anonymity & privacy. I hope that helps & good luck. =D

[TheCentralServices]

Obviously it is possible and I want to do it. Where is the problem?

[Victor Gatto]

[Zaria LaVey]

question is why do you want to "protect" yourself from tor? you can block it but i don't know how. but why do you think it's terrible? it's meant to use for people who don't want the government following every fucking move they make. Jacob Applebaum has a video explaining why.

[TheCentralServices]

Could you make a step by step tutorial on what I have to do to control the whole internet traffic of my country?
