Computer experts from the University of Cambridge were able to breach the “Great Firewall of China” and also have found a way to use the firewall to launch DoS (Denial of Service) attacks.
The firewall was tested by sending data packets containing the word “Falun” to it. This word is a reference to the Falun Gong religious group, which is banned in China. By using forged packets, they were able to circumvent the firewall’s filters.
Furthermore, the Chinese firewall can also be used to launch denial-of-service attacks. The system can essentially be turned around on the Chinese government. Sites could be blocked that the Chinese government wants people to see and others could be let in.
