'Anonymous' hackers to use their expertise against ISIS [VIDEO]

The hacker group "Anonymous" has declared war on ISIS. On Nov. 14, the group of hackers uploaded a YouTube video, detailing their plans on the activist group.

On the video, a man wearing a Guy Fawkes mask announced in French: "Expect massive cyber attacks. War is declared."

"Anonymous from all over the world will hunt you down."

The video has amassed over 1 million views by Monday 9:30 ET says AOL.

"Anonymous" is known for unleashing cyber attacks on various governments, organizations and even individuals. CNBC reports some of its previous victims include Mastercard, Paypal and the Church of Scientology among others.

Although based in areas within Syria and Iraq, the Islamic State or IS has also made several attacks abroad. The most recent massacre included attacking a concert hall and several bars and restaurants in Paris, killing 129 people.

During the weekend, the French government attacked several IS strongholds in Syria, launching several air strikes. A massive manhunt is still ongoing to search for the perpetrators.

David Gerwitz is an expert on cyber warfare. In a recent interview with CBS News he described how the hacker group can inflict damage on the Islamic State.

"They can't be used to arrest people or take terrorists off the field, but they can certainly be used to compromise structural components of terrorist operations. More to the point, they can go after both the money that terrorists have and their funding sources."

"Damaging the money flow can certainly have an impact on the terrorists' operations," he added.

On Twitter, @Group Anon clarifies that this is not the first time that the group is going to war with the Islamic State. In the past, 'Anonymous' has made several attempts to break up ISIS' attempts of recruiting more members using social media.

AOL says that after the attack on the Charlie Hebdo weekly in January, 'Anonymous' also went on the offensive, reporting over 39,000 profiles of suspected ISIS sympathizers to Twitter. Approximately 25,000 have already been suspended.

The group has put up the Lucky Troll Club website which encourages Twitter users to review and report the suspected accounts.

According to CBS News' report, the hacker group could also attempt attacking the terrorist group's accounts on other online networks. On Monday, #opparisofficial says that the group has already taken down at least 3824 accounts on Twitter.
