Hacker group Anonymous has declared war against ISIS in retaliation for the attacks in Paris on Friday night.
The hacktivist group warned ISIS terrorists in a YouTube video, “These attacks cannot be left unpunished. That's why Anonymous worldwide will track you,” a hooded man wearing a Guy Fawkes mask said, speaking in French. “We will launch our biggest cyber attack against you. Wait for many cyber attacks.” The attack in Paris left 129 dead and injured about 350 others.
In January, following Anonymous said it would attack ISIS after the Charlie Hebdo attack and an attack against a kosher grocery. The group launched a campaign to hack into Twitter accounts that publish ISIS propaganda. Anonymous supporters took down the pro-ISIS graphic images in these accounts and replaced the Japanese anime images of little girls with hashtags like #knivesareforcuttingmelon.
ISIS, a group that regularly uses Twitter to attract new recruits, has increasingly seen its members attacked and mocked through social media hacks. Earlier this year, a group of Chechen women lured ISIS terrorists and scammed ISIS out of 45 thousand rubles. The women told their ISIS contacts they wanted to join the group but didn't have enough money to travel to Syria, then cut off contact with the ISIS contact, moved on to another contact and repeated the process.
In September, Anonymous attacked Saudi Arabian government websites in protest against the crucifixion of Ali al-Nimr, a nephew of the Shia cleric and activist Sheikh Nimr Baqr al-Nimr.
