Hacktivists identifying with the entity known as Anonymous announced an impending attack on ISIS following the recent attacks in Paris. They released this video on YouTube:
Yesterday, Friday November 13th 2015, our country, France was attacked in Paris at around 10 PM by multiple terrorists attempts claimed by you, ISIS.
These attacks cannot go unpunished, hence the reason why the anonymous from all over the world will hunt you down. As we did since the attacks of Charlie Hebdo. Therefore, be prepared for a massive retaliation from the Anonymous.
Be advised that we will find you and will not let you go; we will launch the biggest ever operative against you.
Expect massive cyber attacks. War is declared. Get prepared. The French people are stronger than you and will come out of this atrocity even stronger.
Anonymous presents its condolences to the family of all the fallen victims
