Scammers used AI-generated deepfake videos and cloned voices on TikTok to impersonate trusted Nigerian brands and public figures, defrauding users of significant financial sums through fake grants and investment schemes.
Mohammed Yusuf, a small-business operator in Ilorin, Kwara State, Nigeria, reportedly lost about ₦150,000 (~US$108.86) after responding to a purportedly AI-generated TikTok ad impersonating digital payments company OPay. The ad allegedly promised a free payment terminal and cash grant. A caller reportedly posing as OPay staff requested a one-time password; unauthorized betting-voucher transactions reportedly depleted nearly all the operator's business capital.

This incident involves the malicious use of AI-generated deepfakes and cloned voices in Nigerian languages to execute financial scams on TikTok. While the campaign targeted a large audience and caused severe individual financial and psychological distress, its primary impact is criminal fraud rather than a direct threat to national security, infrastructure, or state sovereignty.
The AI systems (voice cloners and deepfake generators) were used as tools by human scammers to perform specific, well-defined functions of generating synthetic audio and video based on direct inputs, without exhibiting independent planning or autonomous decision-making.
Limited Risk: The report describes the use of AI-generated content such as deepfakes and synthetic voices, which under the EU AI Act are subject to specific transparency obligations to ensure users are informed of their synthetic nature.
The primary technology exploited was the generation of realistic synthetic videos and cloned voices of trusted public figures and corporate representatives to deceive victims.
The investigative report is highly detailed, providing specific case studies of named victims, quantifying the number of monitored ads (130), identifying the specific brands and public figures impersonated, and detailing the financial losses and platform mechanics.
