The computer hacker group known as Anonymous has released a trove of data it says was taken from computers belonging to NATO. In a defiant message, Anonymous called the move retaliation for a series of raids targeting alleged members earlier this week. Fourteen of the suspects were arrested for their alleged links to a December attack on the online payment site, PayPal. Anonymous took credit for the breach in response to PayPal’s suspension of accounts that donated money to the whistleblower website, WikiLeaks.
