"War is declared. Get prepared," the masked figure says in the video in reference to ISIS. "The French people are stronger than you and will come out of this atrocity even stronger. Anonymous from all over the world will hunt you down. You should know that we will find you and we will not let you go. We will launch the biggest operation ever against you."

The hacker says that the infamous group will use its cyber skills to "unite humanity" and said that terrorists should "expect massive cyber attacks."
ISIS is yet to respond to Anonymous declaration of war on the group.
The escalation in Anonymous's operation against ISIS comes after at least seven suspected attackers carried out gun and bomb attacks against a number of civilian targets across the French capital, leaving 352 wounded and at least 99 in a critical condition. French police are continuing a manhunt for a man they believe took part in the attacks, identified as 26-year-old Salah Abdeslam.
Anonymous has targeted ISIS for a number of months, revealing the Twitter accounts of ISIS members and hacking a number of the group's sites. U.S. magazine Foreign Policy estimates that the group has dismantled at least 149 of the extremist group's affiliated websites, flagged approximately 101,000 Twitter accounts and nearly 6,000 propaganda videos.
Their campaign against ISIS began after the extremist group's cyber wing hacked the Twitter accounts of U.S. CENTCOM and Newsweek, in January and February respectively, and the radical Islamist attacks on the Paris offices of satirical magazine Charlie Hebdo in January.
