In December 2011, hackers associated with Anonymous and LulzSec breached Austin-based intelligence contractor Stratfor and obtained millions of emails, including authentication information for thousands of credit cards. Barrett Brown, who was not accused of conducting the hack or writing code, posted a link in a Project PM chat to material that had already been published online. Project PM had also examined hacked files concerning intelligence contractors, including an HBGary surveillance proposal involving data-mining tools aimed at Arab countries.
The FBI searched Brown’s apartment and his mother’s home on March 6, 2012, seizing computers and chat logs later used in prosecutions. Brown was arrested on September 12, 2012, over a threatening YouTube video, and prosecutors later added charges tied to the Stratfor material and alleged obstruction. Most charges were dropped in March 2014; he pleaded guilty in April 2014 to accessory after the fact, threatening an FBI agent, and obstruction. In January 2015, he received 63 months in federal prison and was ordered to pay $890,250 in fines and restitution. His mother received six months’ probation and a $1,000 fine for obstructing the search.
