Britain says its military is hacking ISIS

Britain's Defence Secretary Michael Fallon says the British military is launching cyberattacks against the Islamic State group in support of the offensive against militants in the Iraqi city of Mosul.

Fallon says he "can confirm they are using offensive cyber for the first time in the campaign". He was responding to a question in London on Thursday.

He didn't go into any further detail but the admission is a sign of how some officials are tentatively opening up about the use of hacking on the battlefield.
