National Security Adviser Nuhu Ribadu and the African Union Counter-Terrorism Centre have warned that terrorist groups are increasingly exploiting social media, cryptocurrency and emerging technologies to recruit members, conceal financial transactions and coordinate attacks across West Africa and the Sahel.
The warning highlights the growing complexity of the security threats confronting countries in the region, where extremist groups are combining conventional violence with digital tools to expand their reach and sustain their operations.
According to the reported assessment, social media platforms are being exploited to circulate propaganda, influence vulnerable individuals and facilitate recruitment, while digital financial channels can complicate efforts to trace funds associated with terrorism.
The use of emerging technologies also presents challenges for security agencies attempting to identify networks, monitor suspicious activities and prevent attacks before they occur.
The warning comes as governments across Africa continue to confront extremist violence, particularly in the Sahel and the Lake Chad Basin, where armed groups have threatened civilian populations, attacked security personnel and disrupted economic activity.
The African Union has previously raised concerns about terrorist organisations exploiting emerging technologies, including drones, encrypted communication platforms and digital finance, for propaganda, recruitment and operational planning.
Such developments have increased the importance of cooperation between intelligence agencies, financial regulators, law enforcement bodies and technology companies.
Security experts and policymakers face the difficult task of preventing the misuse of digital platforms without unnecessarily restricting legitimate communication, financial services and access to information.
Cryptocurrency transactions, for example, require appropriate investigative capacity and cooperation with relevant service providers to identify suspicious activity. Social media monitoring similarly needs to operate within applicable legal frameworks while protecting legitimate expression and privacy.
The reported warning from Ribadu and the African Union Counter-Terrorism Centre underscores the need for regional cooperation, given that terrorist networks and their financing channels can cross national borders.
Individual countries may struggle to respond effectively when intelligence, financial information and evidence are not shared promptly with neighbouring states.
A coordinated response could include improved intelligence-sharing arrangements, stronger financial investigations, specialised digital-forensics capabilities and measures to prevent the online recruitment of vulnerable individuals.
Governments must also address the conditions that extremist groups exploit, including insecurity, marginalisation and limited economic opportunities in affected communities.
Technology can strengthen counter-terrorism efforts through faster information analysis and improved surveillance, but it must be supported by trained personnel, reliable institutions and clear accountability mechanisms.
The central challenge for Nigeria and its regional partners is to ensure that security strategies evolve alongside the methods used by armed groups, while protecting civilians and respecting the rule of law.
The effectiveness of these efforts will ultimately depend on whether cooperation leads to disrupted financing networks, reduced recruitment and fewer attacks across the region.
