An employee at an undisclosed tech company has received a deepfake audio impersonating the voice of its chief executive officer asking for assistance to finalise an “urgent business deal”, according to a security company that investigated the incident.

US-based Nisos told Vice in a report that it analysed the voicemail that the employee received in June and determined that it was fake, a “synthetic audio” made to fool the receiver.
