Hacking group Anonymous have published the names, addresses and phone numbers of five alleged recruiters working for ISIS. The internet group had first declared a cyber war on ISIS after the Paris Attacks. Now, the anonymous hacktivists from around the world give details as to the whereabouts of five alleged ISIS recuirters living in Afghanistan, Tunisia and Somalia. Furthermore, Anonymous claim to have hacked more than 5,500 Twitter accounts belonging to ISIS supporters, according to the group’s official #OpParisTwitter account that has been opened to share updates on the offensive by Anonymous against ISIS.

The group’s digital weapon is called a Distributed Denial of Service (DDoS) and the attack attempts to shut down web services by overwhelming it with requests from multiple locations. In the past, the technique has been used to take down the websites of the UK’s Serious Organized Crime Agency, the CIA and other sites. Now, it is targeting pro-ISIS websites.

ISIS responds

On its part, ISIS is rising to the challenge in its cyber war with Anonymous by offering instructions to its members as to how to safeguard themselves from cyber attacks.

ISIS sent a post to Telegram (similar to Facebook) with a public service announcement to ISIS members. The message criticized Anonymous and Business Insider, that obtained a copy, states:

“The #Anonymous hackers threatened in new video release that they will carry out a major hack operation on the Islamic state (idiots).”

ISIS then asks “What they gonna hack?” noting that so far Anonymous had hacked only ISIS-affiliated Twitter accounts and emails.

On their part, ISIS terrorists are working on cyber-attacks to take out airports, hospitals, and even Britain’s elecrtricity supply, according to UK media reports.
