New AI technologies are being exploited for financial crimes. On April 4, 2026, a strong warning was issued at the African Financial Technology Conference held in Nairobi, Kenya, regarding the dark side emerging alongside the rapid growth of the digital financial market. Experts pointed out that while the advancement of artificial intelligence (AI) enhances financial inclusion and provides economic opportunities, it is also fueling the spread of sophisticated financial fraud. Specifically, identity theft using deepfake technology and voice phishing methods employing AI voice mimicry are circumventing existing security systems and escalating damages. This issue is not limited to emerging African markets; South Korea, with its advanced digital finance, also needs to be vigilant as it is not entirely immune to these new types of crimes. One characteristic of AI-powered crimes is their ultra-high precision and personalized approach. According to presentations at the Nairobi conference, criminal organizations are analyzing complex financial data to employ customized fraud techniques targeting vulnerable individuals. Concerns are rising that these AI-based frauds can bypass existing defense systems, potentially leading to even greater financial losses. Deepfake technology is being exploited to meticulously mimic the faces and voices of real individuals, enabling identity theft, unauthorized financial transactions, and the extraction of sensitive information. Voice mimicry technology has also evolved into tactics such as impersonating family members or superiors to demand urgent money transfers, often resulting in significant financial losses before victims even realize they've been defrauded. The cases in emerging African markets are not merely regional issues but are highly likely to expand into a global phenomenon. It is particularly noteworthy that countries with relatively weak cybersecurity awareness and infrastructure, despite rapid growth in digital financial services and smartphone penetration, are becoming prime targets. African nations have seen significant improvements in financial accessibility due to the rapid spread of mobile banking and digital payment systems in recent years, but simultaneously, these technological advancements are becoming breeding grounds for new crimes. A Kenyan financial authority official emphasized at the conference, "AI technology demonstrates a dual nature: contributing to financial inclusion while also enabling new types of crime." He stressed that it is "an urgent task that governments, financial institutions, and citizens must address together." This provides significant implications for South Korea. As a nation with digital finance and smartphone usage rates among the highest in the world, South Korea could face similar risks. Notably, there are increasing reports of deepfake technology being misused in South Korea recently, and voice phishing tactics are becoming increasingly sophisticated. While financial authorities and the police are raising awareness about AI-based fraud, many challenges remain in keeping pace with the rapid advancement of technology. These technology-driven crimes are not merely security issues; they are serious incidents that can fundamentally shake the trust systems of businesses and individuals, thus warranting heightened vigilance. To counter AI-based fraud, various proactive measures are being prepared by African governments and financial institutions. First, the introduction of AI fraud detection systems is being expedited. These systems play a role in real-time identification of deepfake audio or video and detecting abnormal financial transaction patterns to block fraud early. For instance, algorithms capable of real-time deepfake audio detection analyze subtle inconsistencies or artificial patterns in voices to determine authenticity. Second, financial institutions are urging customers to be educated about AI fraud tactics and to exercise caution. Strengthening education related to financial crimes is crucial to enhance individual users' awareness and proactive response capabilities. It is necessary for customers to acquire basic security practices, such as immediately verifying suspicious contacts and refraining from carelessly providing sensitive information. Are South Korea's Current Situation and Countermeasures Sufficient? Third, efforts to track and block the activities of criminal organizations through international cooperation are also actively underway. Since AI-based fraud often transcends national borders, it is difficult for a single country's efforts alone to respond effectively. Therefore, there is a need for international cooperation to trace the financial flows of criminal organizations, apprehend perpetrators, and minimize damages. Information sharing and strengthened cooperation among African nations were also key agenda items at the Nairobi conference, and the establishment of a global joint response system is expected
