19 Section 3 STRATEGIC CONTEXT Terrorists Hacktivists 3.11. Terrorist groups continue to aspire to conduct damaging cyber activity against the UK and its interests. The current technical capability of terrorists is judged to be low. Nonetheless the impact of even low-capability activity against the UK to date has been disproportionately high: simple defacements and doxing activity (where hacked personal details are ‘leaked’ online) enable terrorist groups and their supporters to attract media attention and intimidate their victims. 3.13. Hacktivist groups are decentralised and issue-orientated. They form and select their targets in response to perceived grievances, introducing a vigilante quality to many of their acts. While the majority of hacktivist cyber activity is disruptive in nature (website defacement or DDoS), more able hacktivists have been able to inflict greater and lasting damage on their victims. “Terrorists using the Internet for their purposes does not equal cyber­ terrorism. However, by increasingly engaging in cyber-space, and given the availability of cyber-crime as a service, one can assume that they would be in the position to launch cyber attacks” ENISA Threat Landscape 2015 3.12. The current assessment is that physical, rather than cyber, terrorist attacks will remain the priority for terrorist groups for the immediate future. As an increasingly computer-literate generation engages in extremism, potentially exchanging enhanced technical skills, we envisage a greater volume of low-sophistication (defacement or DDoS) disruptive activity against the UK. The potential for a number of skilled extremist lone actors to emerge will also increase, as will the risk that a terrorist organisation will seek to enlist an established insider. Terrorists will likely use any cyber capability to achieve the maximum effect possible. Thus, even a moderate increase in terrorist capability may constitute a significant threat to the UK and its interests. INSIDERS Insider threats remain a cyber risk to organisations in the UK. Malicious insiders, who are trusted employees of an organisation and have access to critical systems and data, pose the greatest threat. They can cause financial and reputational damage through the theft of sensitive data and intellectual property. They can also pose a destructive cyber threat if they use their privileged knowledge, or access, to facilitate, or launch, an attack to disrupt or degrade critical services on the network of their organisations, or wipe data from the network. Of equal concern are those insiders or employees who accidentally cause cyber harm through inadvertent clicking on a phishing email, plugging an infected USB into a computer, or ignoring security procedures and downloading unsafe content from the Internet. Whilst they have no intention of deliberately harming the organisation, their privileged access to systems and data mean their actions can cause just as much damage as a malicious insider. These individuals are often the victims of social engineering – they can unwittingly provide access to the networks of their organisation or carry out instructions in good faith that benefit the fraudster.
