AI cloned voices fool bank security systems

In a startling experiment, a BBC reporter used an AI-cloned version of her voice to bypass bank voice ID systems, exposing the vulnerabilities of current authentication methods.

Advancements in AI voice cloning have revealed vulnerabilities in banking security, as a BBC reporter demonstrated how cloned voices can bypass voice recognition systems. Using an AI-generated version of her voice, she successfully accessed accounts at two major banks, Santander and Halifax, simply by playing back the phrase “my voice is my password.”

The experiment highlighted potential security gaps, as the cloned voice worked on basic speakers and required no high-tech setup. While the banks noted that voice ID is part of a multi-layered security system, they maintained that it is more secure than traditional authentication methods. Experts, however, view this as a wake-up call about the risks posed by generative AI.

Cybersecurity specialists warn that rapid advancements in voice cloning technology could increase opportunities for fraud. They emphasise the importance of evolving defenses to address these challenges, especially as AI continues to blur the lines between real and fake identities.
