The recent HBO hack may have exposed up to 1.5 terabytes of data-7 times what Sony lost in the 2014 cyberattack. Up to now, the script of an upcoming episode of  Game of Thrones and episodes of other popular HBO series have been released by the hackers. But thats far less than the total amount of data that has been hacked. The motivations of this cyberattack are still unclear. The hackers might still release potentially damaging data for HBO and its investors.
