Most terrorist activity concerns the open internet; however there is a share of terrorist exchange in the Darknet too. This concerns mostly fundraising campaigns, the use of illicit markets and advertisement of propaganda hosted on mainstream social media.

Law enforcement must continue to engage with and support social media companies in initiatives to devise common strategies to fight their abuse by terrorist groups.
