HBO today confirmed that it was hit by a cyber attack, which has resulted in upcoming episodes of its original shows as well as content from its hit drama Game of Thrones leaking online.  HBO did not immediately respond to a request for comment, but a spokesperson told Entertainment Weekly that it “recently experienced a cyber incident, which resulted in the compromise of proprietary information.”

The company did not reveal what was stolen, but in a memo to employees, HBO CEO Richard Plepler confirmed that the haul included “some of our programming,” EW says.  Hackers contacted journalists on Sunday night via email to notify them of the breach. They’ve reportedly stolen 1.5TB of data from HBO
