The deepfake dilemma: From financial fraud to reputational crisis

Summary

Deepfake audio and video have become cheap and convincing enough to fool employees and executives. A 2025 Gartner survey found that 43% of cybersecurity leaders had experienced at least one audio deepfake and 37% had experienced video deepfakes in the past year. The article also describes a case at Arup where a roughly $25 million transfer followed a video call with AI-simulated executives.

Mitigation

Until robust dual authentication for phone calls is standard, organizations remain exposed to anyone who can convincingly mimic a CFO or CEO. The source text is cut off before its section on building resilience, so no specific mitigation is stated in the text provided.
