The copy of the complaint uploaded by The Daily Beast mentions Mesri as an expert in computer hacking techniques, who had allegedly worked on behalf of Iranian military to break into the computer systems of the world.
Here's the snag: Mesri is in Iran.
An indictment filed Tuesday in federal court in Manhattan accuses Behzad Mesri of hacking into the cable network's computer system in NY.
Documents show how Mesri began research into HBO's computer networks and staff in May 2017.
Over the next couple months, Mr. Mesri compromised user accounts that belonged to HBO employees and used them repeatedly to gain unauthorized access and steal proprietary information from the company, the indictment said.More news: Consumer group warns of 'Trouble in Toyland'

U.S. federal authorities have charged a man alleged to have been involved in stealing unaired HBO shows and scripts for Game of Thrones.
"Today, winter has come for Behzad Mesri".
A spokesman with the US Attorney's Office said that Mesri had not been arrested, but declined to comment on the suspect's whereabouts.
"A series of criminal cases could increase pressure on lawmakers to act", the Post's sources said. The hack at HBO happened nearly three years after a high-profile breach at Sony Corp., which unleashed a trove of emails that embarrassed top executives. "Yes it's true! HBO is hacked!"
He sent another e-mail: "I have the honor to inform you. that we successfully breached into your huge network" and that "in a complicated cyber operation, infiltration into your network (was) accomplished and we obtained most valuable information". The email concluded with an image of the Night King, a character from "Game of Thrones", and said: "Good luck to HBO".
Mesri allegedly told HBO he took 1.5 terabytes of data, which he threatened to release publicly if the network failed to pay a "nonnegotiable" ransom of US$5.5 million in bitcoin. He has also been accused of demanding $6 million in bitcoin in return.
