HBO is in a bad way - they've been hit by relentless leaks of GoT episodes week after week, to the point that I'm guessing they've just given in to grim resignation that each episode is going to get released before its official date. And that's almost exactly what happened with the season finale that's set to come out next week.

Mr. Smith, the hacking group that's responsible for stealing approximately 1.5 terabytes of data from HBO, actually sent confidential plot summaries and outlines to Mashable. And, surprise surprise, it contains specific details about how season 7 will end.

However, Mashable has declined to publish these details, and in turn saved us from a massive wave of spoilers and leaks.

However, this is what the hacking group had to say about the whole fiasco.

"By the way, we officially inform you and other hundred of reporters whom emailing us that we sold 'HBO IS FALLING's entire collection (5 TB!!!) to 3 customer in deep web and we earned half of requested ransom," the hackers told Mashable via email. "We put a condition for our respected customers and they approved. We will leak many many waves of HBO's internal stuff to punish them for playing us and set an example of greedy corporation."

These guys aren't playing around. We don't know who has access to this information, and when it might be released, so be ready!
