Real-World Examples of AI Voice Cloning Misuse

Case Study: A Voice Deepfake Used to Scam a CEO Out of $243,000

Incident Details

In March 2019, the CEO of an unnamed UK-based energy firm received a phone call that appeared to be from his boss, the chief executive of the firm’s German parent company. The voice on the line had a distinct German accent and the recognizable “melody” of his boss’s speech. Trusting the authenticity of the call, the CEO followed instructions to transfer €220,000 (approximately $243,000) to the bank account of a Hungarian supplier.

The Deception

Unbeknownst to the CEO, the voice on the phone belonged to a fraudster using advanced AI voice cloning technology. The fraudster successfully mimicked the German chief executive’s voice, fooling the CEO into believing the call was genuine. Rüdiger Kirsch of Euler Hermes Group SA, the firm’s insurance company, revealed these details, explaining how the CEO was deceived by the subtle nuances in the cloned voice.

The Scam’s Execution

The scam unfolded over three phone calls. The first call initiated the transfer of funds. In the second call, the fraudster falsely claimed the money had been reimbursed, adding a layer of credibility to the scam. The third call was a follow-up attempt to extract additional funds. At this point, the CEO became suspicious as he noticed discrepancies, such as the reimbursement not appearing and the calls originating from an Austrian phone number.


Despite halting the second payment, the initial transfer had already been completed. The funds were moved from the Hungarian bank account to Mexico and then dispersed to other locations, making recovery difficult.
