Threat actors are using real-time AI voice modification and deepfake audio to bypass voice biometric authentication and trick human agents in call centers (vishing – voice phishing). They can convincingly impersonate customers to perform account takeovers or authorize fraudulent transactions.
Business Impact
This significantly increases the risk of fraud and account takeover (ATO) originating through customer support channels. It undermines trust in voice-based security measures and can lead to substantial financial losses and reputational damage for banks, telcos, and other service providers.
Why It Happened
AI voice technology has advanced to the point where it can convincingly mimic specific individuals in real-time or generate realistic voices that fool both automated systems and human listeners, especially in the context of a brief call center interaction.
Recommended Executive Action
Review call center authentication procedures. Implement multi-factor authentication beyond simple voice recognition or knowledge-based questions (KBAs). Train agents to recognize potential signs of AI-generated audio and escalate suspicious calls for further verification.
