A Dallas grand jury has brought charges against Anonymous spokesman Barrett Brown stemming from the 2011 hack of intelligence vendor Stratfor Global Intelligence.

Brown isn’t charged with committing the hack; just with possessing and transmitting credit card numbers that were stolen in the incident.

He has been in prison since he was arrested in dramatic and public fashion three months ago after posting a threatening video to YouTube. Brown was talking with acquaintances during a Sept. 12 TinyChat session when the feds burst in and took him away. The chat session was later posted to the internet.

The Anonymous spokesman was charged the next day with threatening a federal officer.

This time the charges are are related to a different incident: the 2011 Stratfor hack where credit card numbers and internal e-mail messages were stolen.

According to the grand jury indictment, dated Tuesday, Brown posted a link to a zipped version of the documents stolen in the Stratfor hack on Christmas day 2011 — that counts as trafficking in “stolen authentication features,” the indictment claims. He’s also charged with possessing stolen credit card numbers, Card Verification Values, and other information related to those credit card numbers.

Brown, 31, has been in custody since his Sept. 12 arrest, the U.S. Department of Justice said Friday in a press release announcing the 12-count indictment. He could face a maximum of 15 years in prison if convicted on the most serious of these charges.

The self-proclaimed Anonymous spokesman said he was expecting to face fraud charges after his apartment was raided back in March. He mentioned them in a long, rambling video posted to YouTube the day on the same day he was arrested in September. “I bring in no money. I have $25,000 I brought in the last year from this fucking book deal. that’s it.” he said. “A fucking fraud charge for a fucking writer activist who has no fucking money.”

Later in the video, Brown railed against FBI Agent Robert Smith, saying that he was going to “ruin” Smith’s life “and look into his fucking kids.” The Anonymous activist said he was angry that feds were contemplating obstruction of justice charges against his mother.

The indictment is below.
