Yes, that fascinating group of hackers called, “Anonymous” have declared war against ISIS. ISIS is also known as Daeesh.

The declaration was posted on Youtube on Friday, where a member of the online group promised “massive cyber attacks.”

That member was wearing the group’s feature “anonymous” mask, which in reality is a British Guy Fawkes mask.

The secret member spoke in French during the two minute Youtube clip.

“Expect massive cyber attacks,” the male voice said. “War is declared. Get prepared. Anonymous from all over the world will hunt you down.”

“You should know that we will find you and we will not let you go. We will launch the biggest operation ever against you,” he added.

The masked man read from a script as a newscaster with black and white clips of the response to the terrorist attacks in Paris.

“The French people are stronger than you, and will come out of this atrocity even stronger,” the man finished.

The shadowy group also used Twitter to threaten ISIS.

“We’re also better hackers,” the group warned. “There will be nothing left” of ISIS propaganda sites after Anonymous finishes with them.
