The Twitter accounts of the National Football League, the Kansas City Chiefs, and the San Francisco 49ers all were hacked yesterday with a message that said the attackers were "back" and to demonstrate that "everything is hackable."
The attackers claimed to be OneMine, a hacktivist group thought to be out of Saudi Arabia. According to Yahoo Sports, the group also commandeered the Chicago Bears' Twitter account over the weekend and tweeted that the team had been sold to Turki al-Sheikh, an adviser to the Saudi Royal Court — followed by a "Just Kidding!" tweet.
Bloomberg News reported that more than a dozen NFL teams' accounts had been hacked, including the Green Bay Packers. Other teams' accounts were missing their avatars and banner images.
