6. Operation Tunisia

Date: January 2011 
Victim: Tunisian government 

The Tunisian Revolution, which led to the ousting of President Zine El Abidine Ben Ali, was fought over a number of things—government corruption, unemployment, poor living conditions—but a major sticking point was the lack of freedom of speech. A major instigator in the protests was a WikiLeaks wire that described, in detail, the corruption present in the Tunisian government. Anonymous recruited a number of Tunisian hackers to help take down eight government websites with DDoS attacks.
