LOIC - Low Orbit Ion Cannon
is a network stress testing application, written in C# and developed by "praetox". It attempts a denial-of-service attack on the target site by flooding the server with TCP packets, UDP packets, or HTTP requests with the intention of disrupting the service of a particular host. The program was exploited during Project Chanology to attack Scientology websites, and is currently being used by Operation Avenge Assange (Organized by Operation Payback) to attack the websites of companies and organizations that have opposed WikiLeaks.
