Hope is a very cool place, here are more notes.
Sunday Panels
18:00 Cult of the Dead Cow hactivism panel
The theme of their presentation (even though I left for an hour because I was tipping over from hunger) was Internet access through out the world. The first country of focus was China.
Hacking China seems like a pretty big deal. Internet access is limited by the government and the web starts with deny all and government approved web sites are whitelisted, essentially making the web no longer public and free. She called on hackers from around the world to devise solutions to this problem and break through China's restrictions and provide a public service to the world, essentially to liberate China's 1.3 billion citizens.
How is the public involved in filtering policy on the Internet? You can trace back who is making the decisions about what content gets filtered and for what reason they can be entered into a networked database. This can map the relations into a traceable system. Policy can be altered and patterns can be identified as the database expands.
University of tornoto has a hactivism lab that anaylizes how different ISP throught the world block and filter their citizen's web access. Many countries in Asia that have dictatorial governments participate in web filtering. Most of these countries buy their filtering software through American distributers, who most likely aren't concerned with their target audience rights.
- Uzbekistan uses redirects to push their users away from controversial sites
- Saudi Arabia has a blocked page notice with a unblocking request form
- Myanmar uses a blacklist
The commercial blocking software uses flawed automatic keyword categorization from a pre-defined index that has lots of false positives. The moral of the story is keyword blocking systems suck and they will trap your from viewing legitimate content.
20:00 Breaking Corporate Restristions from the Inside
Wrap your outgoing packets with a port that you know is allowed out of the LAN and send it to a second proxy on the Internet that you have set up which is listening on port 80. This can then unwrap the wrapped TCP packet and forward it to it's destination. There are three computers in the equation, whereas no-proxied port forwarding requires two. The thrid in this equation is the proxy server that's shutting you out. htc -P proxy:8080 -F 8000:proxy2:80. Then on the proxy2 server, the unwrapping is done with a server.
