OurMine Takes Over Netflix, Marvel and NFL Twitter Accounts

“Hey, it’s OurMine, we are just testing your security,” read tweets from several prominent brands Wednesday, including Netflix U.S., Marvel Entertainment and the National Football League.

The hacker group OurMine took over Netflix’s U.S. account Dec. 21, according to Reuters. The group also accessed Marvel and the NFL accounts, though the takeovers seemed short lived and tweets were quickly deleted, CNET reported.

OurMine takes over high-profile Twitter accounts to advertise its security services, previously hitting targets such as Twitter's Jack Dorsey and Facebook’s Mark Zuckerberg and celebrities including actor Channing Tatum and DJ DeadMau5.
