NEWSWEEK: Anonymous’s two-minute video threatening ISIS has amassed more than five millions views since it launched on Saturday. “War is declared. Get prepared,” a masked figure warned the group in the video. “The French people are stronger than you and will come out of this atrocity even stronger,” the figure added. “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.” The hacker said that the infamous group will use its cyber skills to “unite humanity” and said that terrorists should “expect massive cyber attacks.” Anonymous has targeted ISIS for a number of months following the attacks on the Paris offices of satirical magazine Charlie Hebdo and its hack of U.S. CENTCOM and Newsweek’s Twitter accounts. The group has uncovered the Twitter accounts of ISIS members and hacked a number of the group’s sites. The hacktivist group has dismantled at least 149 of ISIS’s affiliated websites, flagged approximately 101,000 Twitter accounts and nearly 6,000 propaganda videos, U.S. magazine Foreign Policy estimates.

RELATED: The Islamic State militant group (ISIS) released a statement on Monday responding to Anonymous’s declaration of “total war,” calling the hacker group “idiots” 
and offering guidance to pro-ISIS supporters to protect against cyber attacks. “The Anonymous hackers threatened in new video release that they will carry out a major hack operation on the Islamic State (idiots),” ISIS’s post read. “What they gonna hack…all they can do is hacking twitter accounts, emails etc…” The militant group then listed a series of steps that its supporters should follow online, including not opening suspicious links, changing their locations using workaround technology on their phones and computers, avoiding contact with unknown people on their phone and computers and to renaming their email addresses. The post says: “Do not talk to to people u don’t know on telegram and block them if u have to cause there are many glitches in telegram and they can hack you by it. Don’t talk to people on twitter DM cause they can hack u too. Do not make your email same as your username on twitter this mistake cost many Ansar (helpers) their accounts and the kuffar published their IP so be careful.” MORE
FOREIGN POLICY: For more than a year, a ragtag collection of casual volunteers, seasoned coders, and professional trolls has waged an online war against the Islamic State and its virtual supporters. Many in this anti-Islamic State army identify with the infamous hacking collective Anonymous. They are based around the world and hail from every walk of life. They have virtually nothing in common except a passion for computers and a feeling that, with its torrent of viral-engineered propaganda and concerted online recruiting, the Islamic State has trespassed in their domain. The hacktivists have vowed to fight back. The effort has ebbed and flowed, but the past nine months have seen a significant increase in both the frequency and visibility of online attacks against the Islamic State. To date, hacktivists claim to have dismantled some 149 Islamic State-linked websites and flagged roughly 101,000 Twitter accounts and 5,900 propaganda videos. At the same time, this casual association of volunteers has morphed into a new sort of organization, postured to combat the Islamic State in both the Twitter “town square” and the bowels of the deep web.
