Cable giant HBO’s very embarrassing 2017 has continued to get more embarrassing. On Wednesday night, hacker squad OurMine Security Group compromised Game of Thrones’Twitter account, posting a message to its 6 million plus followers saying “Hi, OurMine are here, we are just testing your security.” “HBO team please contact us to upgrade the security - ourmine .org -> Contact,” the hackers added. The post has since been removed.
