The purloined data included scripts and plot summaries of unaired episodes of 'Game of Thrones, ' Kim added.
Mesri once worked for the Iranian government as a hacker, where he attacked nuclear software systems and Israeli infrastructure, according to the grand jury indictment released Tuesday. The hacker gradually released stolen materials on the internet, including unaired episodes of "Ballers", "Barry", "Room 104", "Curb Your Enthusiasm" and "The Deuce". The decision to indict him is part of a "name and shame" strategy the US government has used in the past to try to curb the work of foreign hackers it doesn't expect to apprehend.
The U.S. Attorney's Office for the Southern District of NY plans to hold a press conference at 12:30 p.m. regarding its case of Behzad Mesri, who is accused of stealing 1.5 terabytes of data from HBO servers earlier this year. "He will never be able to travel outside of Iran without fear of being arrested and brought here to face these charges", Kim said.
One of those targets, the feds allege, was HBO. He is accused of compromising multiple user accounts, and in July of sending an anonymous email to HBO personnel saying: "Hi to All losers!" By July, Mesri was allegedly leaking episodes of scripts and claiming to have obtained 1.5 terabytes of data. No actual Thrones video was ever leaked as part of this particular HBO hack, however.More news: British motorcyclist Daniel Hegarty dies after crashing in Macau Grand Prix
Because of the new indictment, Kim said, the suspect will not be able to leave his home country without risking arrest and extradition to the United States.
The cyber attack surfaced over the summer as HBO was running a new season of "Game of Thrones" and as the cable network's parent Time Warner Inc sought regulatory approval to sell itself to AT&T Inc in an $85.4 billion deal announced in October 2016. Now, after plenty of investigating, the US Department of Justice has found the culprit and issued an indictment.
There will be a Federal Bureau of Investigation press conference on Tuesday at 12:30 p.m.to announce the charges against Mesri.
In a statement in August, HBO said that was not communicating with the hacker.
