The hackers posted a message on Ghostbin, calling for people to mock ISIS , saying, "We ask you to show your support and help against ISIS by joining us and trolling them // do not think you have to be part of Anonymous, anyone can do this and does not require special skills."

"We ask you to take part of this on Facebook // Twitter // Instagram // Youtube //In the "Real World," Anonymous said.
