“They picked a fight with Anonymous when they attacked Paris, and now they should expect us,” he said, adding that the collective “will not sit by and watch these terror attacks unfold around the world.”
Anonymous has targeted ISIS in the past, dismantling 149 Islamic State websites so far this year, according to Foreign Policy. The hacktivist group began operations against the Islamic State following their brutal attack on Charlie Hebdo in January.
On Monday, Anonymous released a video announcing that the group would “launch the biggest operation ever” against Islamic State.
The hacking collective vowed to “unite humanity,” warning the terrorist group to “expect massive cyber-attacks.”
