Digital World War: Islamists, Extremists, and the Fight for Cyber Supremacy, with Haroon Ullah

Despite defeats like Mosul and Raqqa, ISIS and other extremist groups are thriving, says Ullah. For them, the most important battlefield is not the physical one but the information one, and there they are winning. They are nimble, moving from open-source platforms to encrypted ones and are not afraid to fail, getting instant feedback on what propaganda works best. We need a much more concerted effort--a "Manhattan project"--to combat this.
