On April 8, 2015, the pro-ISIS hacker group CyberCaliphate successfully hacked the TV5Monde television network in France and took over its live broadcast, website, and Facebook page. At the time of the attack, the director general for TV5Monde told AFP: "We are no longer able to broadcast any of our channels. Our websites and social media sites are no longer under our control and are all displaying claims of responsibility by the Islamic State."
Both the station's website and Facebook page (pictured above) were defaced with pro-ISIS images and messages in English, French, and Arabic.
