In January 2015 , Anonymous released a video and a statement via Twitter condemning the attack on '' Charlie Hebdo '' , in which 12 people , including eight journalists , were fatally shot . The video , claiming that it is " a message for al-Qaeda , the Islamic State and other terrorists " , was uploaded to the group 's Belgian account . The announcement stated that " We , Anonymous around the world , have decided to declare war on you , the terrorists " and promises to avenge the killings by " shut ting down your accounts on all social networks . " On January 12 , they brought down a website that was suspected to belong to one of these groups . Critics of the action warned that taking down extremists ' websites would make them harder to monitor
