The term "419" originates from the section of the Nigerian Criminal Code dealing with fraud, yet its implications vary widely across different audiences: it may be unfamiliar or insignificant to some, carry technical connotations within IT security circles, and possess a deeply negative resonance in African communities, especially in Nigeria. These scams, characterised by the fraudulent solicitation of advance fees with the promise of lucrative returns, have adeptly harnessed digital platforms to penetrate diverse sectors globally. Through a thorough analysis of contemporary literature and mixed methods research consisting of interviews of key cybersecurity professionals from different industries in addition to wide distributed surveys, this research sheds light on the sophisticated tactics employed by fraudsters, including advanced phishing, social engineering, and the manipulation of business email communications. It highlights the extensive financial and reputational repercussions for entities ensnared by such schemes. By evaluating the effectiveness of current deterrents, the paper proposes a holistic strategy for mitigating risks, advocating for the integration of cutting-edge cybersecurity measures, comprehensive employee training programs, and stringent legal frameworks. The aim of this research is to understand how and why 419 scams have transitioned from simple scams into international cybercrime networks and what it means for corporate security.
