Deepfake Voice Attacks are Outpacing Defenses: What Security Leaders Should Know

Deepfake voice and video attacks (AI-generated replicas of real people) are becoming increasingly common and costly, with tools that require only three seconds of audio and cost almost nothing to create. Attackers target finance employees and IT staff by impersonating executives on calls or video meetings to authorize large money transfers or credential changes, and these attacks bypass traditional security tools because they rely on tricking people rather than exploiting software vulnerabilities. Organizations that have successfully stopped these attacks all used the same defense: training employees to pause and verify requests before acting on them.
