Op Brussels
Anonymous have threatened to "punish" the Islamic State for their attacks on BrusselsYouTube

Hacktivists Anonymous have again threatened the Islamic State (Isis) with cyber warfare saying that they will 'punish' the jihadists. The international hacking group targeted Daesh (Isis) after the Paris terror attacks in November 2015.

Anonymous is known for taking on high-profile targets such as Republican frontrunner Donald Trump and scandal-hit Brazilian President Dilma Rousseff in just the last few weeks. And now they have again threatened the Muslim extremists with another "strike".

The Brussels attacks have claimed the lives of 35 people in two suicide blasts at Zaventem Airport and Maelbeek Metro Station. Two brothers Ibrahim El-Bakraoui and Khalid El-Bakraoui are thought to have carried out the attacks and an international manhunt is underway for Najim Laachraoui a third suspect.

Appearing in the video was one masked man who spoke with a computerised voice who used the hashtag #OpBrussels to promote the actions and encourage others to join in. The speaker declares: "Our freedom is once again under attack. This cannot continue.

"Following the attacks in Paris last November, we have fought daily against terrorism and we have silenced thousands of Twitter accounts directly linked to ISIS. We severely punish Daesh on the dark net, hacked their electronic portfolio and stolen money from the terrorists."

The masked man goes on to say that, following Daesh's Paris attacks, they shut down "thousands" of the jihadists Twitter accounts and stole money and bitcoins from online accounts. The threats continue: "We have laid siege to your propaganda websites, tested them with our cyber attacks, however we will not rest as long as terrorists continue their actions around the world.

"We will strike back against them. We will keep hacking their websites, shutting down their Twitter accounts and stealing their Bitcoins. We defend the rights of freedom and tolerance.

"To the supporters of Daesh, we will track you down, we will find you, we are everywhere and we are more than you can imagine. Be afraid. When they killed innocent civilians in Belgium, they hit everybody in Europe. We have to fight back."

Anonymous has many factions including LulzSec and the New World Hackers with varying ideologies and memberships. But Anonymous has no traditional leadership structure and anyone can join simply by claiming they are a member which remains its greatest strength and its greatest weakness.

And in the latest video the speaker asks everyone to join their campaign. He says: "Everyone can contribute to our efforts and we invite you to fight with us. You will find the link with this video, which will indicate how.

"But you don't have to hack them, if you stand up against discrimination in your country, you will harm them much more than by hacking their websites. The Islamic State cannot recruit Muslims in Europe if they are accepted and included in the society. So we want all of you to stand together against discrimination."

It ends with the message: "We are Anonymous, we are legion, we do not forgive, we do not forget, we are free. Respect us."
