Activist hacking group Anonymous have declared this Friday December 11 a "trolling day" against the terrorist group that calls itself Islamic State (ISIS) as part of its cyber campaign against the militant Islamist group.
In an online message, Anonymous asked people to mock ISIS, or "Daesh" as it is also known in the West (a derogatory term for the group) online as part of its "Operation ISIS" campaign.
"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," the post on file-sharing website Ghostbin added.
Trolling is the term given to abuse, insults or threats made online with celebrities often being the targets of internet "trolls."
Anonymous asked them to use the Twitter hashtags #Daesh and #Daeshbags and post "mocking photos" of the group – such as posting picture of goats to ISIS members with captions talking about their wives, amongst other trolling tactics.
"Idiots"
Known as "hacktivists," Anonymous are a collective of unknown hackers who have carried out various cyberattacks on governments and corporations. Following the November 13 terrorist attacks in Paris in which 130 people died, the group declared "war" on ISIS and announced it would conduct "massive" cyber attacks on the group.
ISIS, meanwhile, responded to the threat by calling the hackers "idiots" although it appears to have since posted advice on the Telegram messaging site to supporters on how to prevent being hacked.
Many of ISIS' supporters and members have social media accounts and the Jihadist group, which operates in Syria and Iraq, has a strong online presence, Anonymous claims it has already taken down hundreds of Facebook and Twitter accounts belonging to ISIS.
For anyone wondering why Anonymous is "trolling" ISIS, the poster offered an explanation:
"You may be wondering why we are "trolling" Isis and planning all these demonstrations against Isis. But to understand that you must first see how Isis works. They thrive off of fear they hope that by their actions they can silence all of us and get us to just lay low and hide in fear. But what many forget and even they do is that there are many more people in the world against them than for them," the poster said.
"And that is the goal of this mass uprising, on December 11th we will show them that we are not afraid, we will not just hide in our fear, we are the majority and with our strength in numbers we can make a real difference. We will mock them for the idiots they are."
