Anonymous (hacker group)
Anonymous is a group of anonymous online Activism activists. They are associated with many online and offline protests. These protests commonly relate to freedom of speech. They often protest against political corruption and censorship. Anonymous also makes DDoS attacks (where an attacker disconnects his or her target from the internet, sometimes forever) on popular websites such as PayPal and the United States' Department of Justice homepage. Other common targets include organizations who seem to limit people's freedom of speech.
