An automated email reply message from the hackersobtained byVarietyon Thursday contained a pledge to gradually upload more material.

The message also reportedly reiterated the hackers claim that 1.5 terabytes of content were stolen.

But the report also noted that only 300 megabytes from HBO have been released so far.

So if the 1.5 terabyte claim is correct, it still means theres a considerable amount of unreleased material.

Ultimately what the hackers have is still very much a mystery.

EW wasfirst to reportthe hack, which last Sunday included upcoming episodes ofRoom 104andBallers.
