On January 9, 2015, a hacker group calling itself L'Apoca-Dz successfully hacked and defaced a number of French websites with messages condemning satirical publication Charlie Hebdo after the terrorist attack on its offices on January 7. Websites targeted were ones belonging to the French towns of Goussainville, Ezanville, Jouy-le-Moutier, Piscop, and Val D'Oise. The defaced pages featured the above image, which includes the message: "The Islamic State Stay Inchallah, Free Palestine, Death To France, Death To Charlie." Some reports claim the hacker group is Algerian.
