A major Indonesian financial institution found deepfake fraud inside its mobile app despite running multi-layered security, and brought the problem to Group-IB in August 2024. Group-IB's investigation found roughly 1,000 fraud cases among 2 million users, a detection rate of just 0.05%. Over the following year the same institution logged 8,065 separate attempts to fool its liveness checks with AI-generated faces during digital KYC for loan applications, described as a technique run at volume rather than one clever attacker.
