This dimension of terrorism funding has become a critical source for terrorist organisational mobilisation. The cyber funding of terrorism has coincided with the remarkable technological progress that has been achieved in the last few decades. This chapter provides a general background to the development of cyber terrorism funding. Then, it introduces relevant areas surrounding the cyber dimensions of terrorism financing that are currently challenging scholars, experts, and policymakers alike, including discussions on social media, cryptocurrencies, and the dark web. The chapter then discusses some technological tools and initiatives needed to counter the evolving nature of cyber terrorism funding through artificial intelligence techniques and protocols. Finally, it concludes with a discussion on future challenges. One potential tool that can aid in preventing terrorism funding is the utilisation of artificial intelligence.
