An ISIS-affiliated account on the messaging app Telegram has sent out a message about Anonymous’ threat to launch its “biggest operation ever” against the terrorist group.
After the Paris terror attacks on Friday that left at least 129 people dead and hundreds more injured, the hacking collective Anonymous posted a video in which a person who claims to represent the group said, “Anonymous from all over the world will hunt you down.”
“We will launch the biggest operation ever against you,” the masked person said. “Expect massive cyber attacks. War is declared. Get prepared.”
A Telegram channel that’s believed to be affiliated with ISIS hackers then sent out a message to its followers instructing them how to prevent getting hacked by Anonymous.
The message goes on to provide “instructions” on how to avoid potential hacks: Don’t open any links unless sure of the source. Change Internet Protocol addresses “constantly.” And “do not talk to people [you] don’t know on Telegram” or through Twitter direct messaging.
The message was then forwarded around to various other ISIS-affiliated Telegram channels.
Anonymous started targeting extremists in January after the terror attacks on the satirical French magazine Charlie Hebdo. The hackers worked to identify ISIS-linked social media accounts and take down extremist websites.
“The Anonymous hackers threatened in new video release that they will carry out a major hack operation on the Islamic State (idiots),” the statement read in part.
