Over a dozen NFL teams may want to consider hiring a cyber defensive coordinator after their Twitter, Instagram and Facebook accounts were reportedly hijacked and defaced on Sunday and Monday by the mischievous OurMine hacker group, which has emerged from hibernation.

According to multiple news sources, the hackers compromised the NFL's league Twitter and Facebook account, as well as social media accounts belonging to the Buffalo Bills, Arizona Cardinals, Chicago Bears, Cleveland Browns, Dallas Cowboys, Denver Broncos, Green Bay Packers, Houston Texans, Indianapolis Colts, Kansas City Chiefs, Los Angeles Chargers, Minnesota Vikings, New York Giants, Philadelphia Eagles, San Francisco 49ers and Tampa Bay Buccaneers.

The Bears appear to have been the first team that was victimized. The hackers published a tweet claiming that the franchise had a new owner and included photo of Saudi official Turki Al-Sheikh, chairman of the Islamic Solidarity Sports Federation (ISSF). A follow-up post revealed the ruse, stating: "Hi we're OurMine. We're here for 2 things: 1) Announce that we're back 2) Show people that everything is hackable."
