The 10 Biggest Security Stories Of 2011


Whistleblower site WikiLeaks made news this year as perpetrator and victim. The site published in August another batch of U.S. diplomatic cables that came from a comprehensive cache of 250,000 State Department documents. The site released the first batch in November 2010.

Within days after the August release of 134,000 cables, WikiLeaks was struck by a denial-of-service attack, apparently in retaliation. About 170 cables named U.S. diplomats whose identities were protected, including a United Nations official in West Africa and a foreign human rights activist working in Cambodia. The release-attack scenario was similar to what happened in 2010, when a hacker calling himself The Jester took credit for shutting down the site. The perpetrators of this year's attack are not known.
