The accounts of several HBO series, including "Last Week Tonight with John Oliver," "True Blood," "Veep" and "Vinyl," tweeted a message Wednesday night purporting to be from the notorious OurMine hackers. It appeared that only U.S.-based accounts were affected — @HBOUK and @HBOCanada appeared to emerge unscathed, for example.

HBO regained control of the accounts within about 40 minutes and deleted the tweets, which NBC News archived before they were taken down:
HBO told NBC News late Wednesday only that "we are investigating."
OurMine, sometimes called OurMine Team, has been blamed for taking over social media and other online accounts of several prominent people and institutions in the last 2½ years or so, including those of Google Chief Executive Sundar Pichai, Facebook Chief Executive Mark Zuckerberg, Wikipedia co-founder Jimmy Wales, BuzzFeed and TechCrunch. Many of the messages mirrored those that were posted Wednesday night.
OurMine is anonymous, and it couldn't be determined Wednesday night whether it was, in fact, behind the HBO hack. In all of Wednesday night's tweets, the name "OurMine" was rendered with faint accent marks — as "Our⁻Mi⁻ne," not "OurMine" — a construction that the hackers aren't known to have used before.
HBO said it didn't have enough information to discuss that.
