Pokemon Go creator Niantic's Twitter account hacked

Hacking group OurMine on Tuesday broke into the Twitter account of John Hanke, the CEO of Niantic

After hacking Pokemon Go servers last month, hacking group OurMine on Tuesday broke into the Twitter account of John Hanke, the CEO of US-based software company Niantic that created the popular GPS-based augmented reality game with Japanese company Nintendo.

OurMine took control of Hanke's account and posted a series of tweets, including one that identified Hanke's password as "nopass", Tech Crunch reported.

The hackers posted the #OurMine hashtag within tweets on Hanke's account.

In July, the hacking team hit Pokemon Go's login servers with a distributed denial of service (DDoS) attack leaving some players frustrated as they were unable to log in to the game.

The group said it would not stop the attack until representatives from Pokemon Go contacted them.

"No one will be able to play this game till Pokemon Go contact us on our website to teach them how to protect it!" the group wrote in a post on its website.

A DDoS attack works by flooding a server with traffic so that it cannot be accessed by legitimate users.

OurMine has also claimed credit for compromising Twitter chief executive officer (CEO) Jack Dorsey's, Facebook chief Mark Zuckerberg's and Google CEO Sundar Pichai's social media accounts.

The group also hacked the Twitter account of Evan Williams, the microblogging site's co-founder and former CEO.
