A LOIC (Low Orbit Ion Cannon) is one of the most powerful DOS attacking tools freely available. If you follow news related to hacking and security issues, you doubtless have been hearing about this tool for the past several months. It has become widely used, including in some highly-publicized attacks against the PayPal, Mastercard and Visa servers a few months back.
This tool was also the weapon of choice implemented by the (in)famous hacker group, Anonymous, who have claimed responsibility for many high profile hacking attacks, among them, hacks against Sony, the FBI and other US security agencies.
