1. DNS Poisoning, redirecting to the China Unicom website
2. Hidden proxy in the middle that filters the GET requests it forwards.
3. Playing the Big Man In The Middle, and terminating the connection whenever a TCP packet containing things such as signature Youtube HTML code.
This means that the Great Firewall of China can be the best tool for hackers to exploit. This also means that the Communist Party can commit identity theft simply by going over to the MITMS and proxies and monitoring the traffic.
P.S. I have actually successfully hacked the component of the GFW in schools, Green Dam Youth Escort. I will tell you more about it if you ask in the replies.
