It sounded exactly like your CFO. It wasn’t.
A few seconds of audio are enough to clone a voice. Combine that with a spoofed number, and every signal your staff rely on can be faked at once.
What happens in practice
The urgent payment
The controller gets a call from the CFO’s number, in the CFO’s voice, about a confidential acquisition. Within an hour the money is gone.
The deepfake video call
At Arup in 2024, an employee transferred some $25.6 million after a video call in which everyone, including the CFO, was faked.
Fraud in your name
Criminals pose as your executives towards suppliers or investors. Your name is used, your reputation damaged.
The figures
- Rotterdam-based Jewometaal lost €11 million to classic CEO fraud.
- Detecting high-quality deepfakes in live situations is barely better than guessing.

What the rules require of you
Under NIS2 and DORA, relying on a familiar voice or a recognisable number is no longer a defensible control. A technical measure in the payment process is.
