Anonymous calls ISIS a 'virus,' promises to disrupt group online

The Anonymous hacker collective is taking aim at ISIS in Syria and Iraq, launching attacks to disrupt the group's social media accounts. As part of its #OpISIS campaign, Anonymous has taken down hundreds of Twitter, Facebook, and other social media accounts linked to ISIS - used to spread propaganda and woo potential recruits.

"ISIS: We will hunt you, take down your sites, accounts, emails and expose you," Anonymous pledges. "From now on, no safe place for you online... you will be treated like a Virus, and we are the cure. We own the Internet. We are Anonymous; we are Legion; we do not forgive, we do not forget. Expect us."

In addition to listing Twitter and Facebook accounts - of both compromised accounts and possible targets - Anonymous has revealed email addresses, IP addresses, VPN connections and websites used by the extremist group.
