Anonymous has declared “war” on ISIS in response to the attacks in Paris that left more than 100 people dead.
Members of the online collective have posted a video. It continues the group’s work against ISIS, which began strongly after the Charlie Hebdo attacks in January.
In a video posted soon after the attacks, a person claiming to represent the group warns members of Islamic State that it intended to hunt them down. It said it would “unite humanity” in the operation, which it said would use hacking to weaken the group.
“Anonymous from all over the world will hunt you down,” said the voice in the video, which included footage of the group’s ubiquitous Guy Fawkes mask and was in French. “You should know that we will find you and we will not let you go.
“We will launch the biggest operation ever against you.
“Expect massive cyberattacks. War is declared. Get prepared.
“The French people are stronger than you and will come out of this atrocity even stronger.”
The video has been watched almost a million times, and thousands of people have shared tweets about Anonymous’ call to action. Across Twitter, users said they would shut down social-media accounts and websites, as well as claiming to help disrupt communications.
Anonymous has made repeated calls to action against ISIS since the Charlie Hebdo attacks in January. Very shortly after the attacks, it started taking down extremist websites, and it has been running campaigns on social media ever since.
The group has been particularly active on Twitter, where it has worked to identify ISIS social-media accounts — often used to distribute propaganda and share news releases — and then report them to the company so they can be taken down.
