Brief introductions

1. FreeGate (自由门)

FreeGate is an anti-censorship software for secure and fast Internet access  developed and maintained by Dynamic Internet Technology Inc. (DIT: www.dit-inc.us), a  pioneer in censorship-circumvention operation, which was founded originally in 2001 to provide email delivery services to China for U.S. government agencies and NGOs.

FreeGate works by tapping into an anti-censorship backbone, DynaWeb, DIT’s P2P-like proxy network system and a web-based anti-censorship portal. Once users point their web browser at one of the DynaWeb URLs, a web page will be presented similar to the one at us.dongtaiwang.com, with most blocked websites as links. In addition, a user can type in any URL in the box on this page and DynaWeb will fetch the pages for him/her instantly. No software is needed, nor are any settings tweaked on a user’s computer.

But since the Chinese net police watch DynaWeb’s portal websites closely and block them as soon as they identify them, DynaWeb must indeed be very dynamic. It has hundreds of mirror sites at anytime, and each with a varying IP and DNS domain name, to defeat IP blocking and DNS hijacking. On the backstage, DynaWeb also has mechanisms to proactively monitor the blocking status of each of its mirror sites, and as soon as blocking is detected, it will change the IP and DNS domain name instantly.

There are indications that FreeGate has some capabilities built-in to exploit some zero-day vulnerabilities of Chinese regime’s Great FireWall (GFW).
