Sunday those claiming to represent the Internet hacktivist group known as "Anonymous" launched a cyber attack against The American Israel Public Affairs Committee (AIPAC). The attack is aimed at the website, aipac.org, and conducted via a modified LOIC (Low Orbit Ion Cannon) used to execute DDoS attacks. A distributed denial-of-service attack (DDoS attack) is an attempt to make a computer resource unavailable to its intended users.
According to the announcement from Anonymous:
America's Pro-Israel Lobby (AIPAC) is known for being one of the most powerful lobbies, keeping politicians in their pockets. During 2009, the U.S. provided Israel with at least 8.2 million per day in military aid and $0 in military aid to the Palestinians.
We are having none of it.
The notice goes on to give "attack instructions" on the installation and utilization of the LOIC (low orbit ion cannon)
