A group called OurMine appears to have taken control of the main HBO accounts, as well as those for the network’s shows including Game of Thrones.
One post said “OurMine are here. we are just testing your security”.
OurMine is notorious for hacking high-profile social media handles, and has in the past managed to compromise the social media accounts. Last year it compromised Netflix, as well as Wikipedia co-founder Jimmy Wales, Facebook co-founder Mark Zuckerberg and Google chief executive Sundar Pichai.

It is the latest cyber security headache for the entertainment firm after hackers released Game of Thrones scripts and company data
The hack is the latest in a string of security setbacks for HBO in recent weeks.
Unidentified hackers claim to have stolen 1.5TB of data from the company in July.
Out of the haul they released Game of Thrones scripts, company documents and unbroadcast episodes of HBO’s other shows including Curb Your Enthusiasm and Insecure.
