The Importance of Dark Web Access in Cyber Threat Intelligence

Cyber Threat Intelligence (CTI) is essential in in-forming proactive cyber defence, especially in Nigeria's most significant sectors: financial services, telecommunications, and healthcare. This study reviews the current body of CTI lit-erature, examines intelligence obtained from the Dark Web, and determines impending threats, including Ransomware-as-a-Service, zero-day exploits, and phishing toolkits aimed at these sectors. Performing qualitative platform analysis of the likes of RaidForums and Exploit.in, we determine sectoral vulnerabilities and offer pragmatic suggestions on developing Nigeria's cyber defence system. The findings underscore the Dark Web's role as a vital source of intelligence to counter cyber threats under low-resource conditions, filling Nigeria's gaps in CTI capabilities.
