The Internet Cannon that China is touting is a technology most hackers have been using since 2010. LOIC, or the Low Orbiting Ion Cannon, is a DDoS tool. It was originally just a stress testing tool, then was converted to a DoS (Denial of Service) tool, now with it’s option to connect to a botnet (or hive), it can DDoS (Distributed Denial of Service).
China has been ‘marketing’ that any website that China does not approve of, in the name of censorship, will be blasted with the Internet Cannon.
