Jeremy Fleming, the director of GCHQ, announced that Britain carried out its first major cyber-attack in 2017 with the target being Islamic State.
The attack was reportedly successful in disrupting Islamic State's communications and propaganda infrastructure Fleming told a cybersecurity conference in Manchester.
“For GCHQ, this expansion of the terror threat means more investment in our people and our capabilities. Closer working with other CT partners here and overseas and greater sharing of our information to improve the threat radar. But it's also brought a sharper focus on fighting Daesh online.
