Anonymous declares war on Hebdo terrorists and the "enemies of freedom of expression."

As unsettling as ever, Anonymous will be going after the terrorists inspired by the Charlie Hebdo terrorist attackers:

Telegraph: Hacker group Anonymous have released a video and a statement via Twitter condemning the attacks on Charlie Hebdo, in which 12 people, including eight journalists, were murdered. The video description says that it is "a message for al-Qaeda, the Islamic State and other terrorists."

In the clip, a figure wearing the group's symbolic Guy Fawkes mask is seated in front of a desk with the hashtag #OpCharlieHebdo - which stands for Operation Charlie Hebdo - featured on screen.

"We are declaring war against you, the terrorists." They add that the group will track down and close all accounts on social networks related to terrorists in order to avenge those who have been killed. This is backed up with a statement entitled "a message to the enemies of freedom of expression ... freedom of expression has suffered inhuman assault ... and it is our duty to react."

The hacker collective offered their condolences to "the families of the victims of this cowardly and despicable act".

In the past the group have carried out cyber attacks on government, religious, and corporate websites by distributed denial-of-service (DDoS) attacks which attempt to overwhelm an online service with traffic from numerous sources so that users can no longer access it.
