Newsweek magazine’s Twitter account, @Newsweek was hacked by terrorist group, “Cyber Caliphate,” the group claims to be associated with the Islamic State in Iraq and Syria or better known as ISIS. The group also hacked other well-known Twitter accounts such as @Centcom, account of the United States Central Command.

The Newsweek account remained hacked for 14 minutes before the Twitter support team could regain control. The main banner and profile picture were replaced with a masked man, the Black Standard flag, a flag that is flown by Muhammad in Islamic tradition and the phrase “Je Su IS IS,” referring to the “Je Suis Charlie” or “I am Charlie” slogan used back to the deadly attacks in Paris this past Jan.

The hacked account released documents from the U.S National Cyber Security Center and wishing Michelle Obama and her family a “Bloody Valentine’s Day.” All images and tweets were deleted after.

“We can confirm that Newsweek’s Twitter account was hacked this morning, and have since regained control of the account,” Newsweek managing editor Kira Bindrim said in a statement. “We apologize to our readers for anything offensive that might have been sent from our account during that period, and are working to strengthen our newsroom security measures going forward.”

The Cyber Caliphate were also reported to be behind the hacking of Malaysia Airlines Website in Jan.
