Can a deepfake call or video trick our finance team into paying?
Yes, and the defence is a process, not a technology. With a few minutes of public audio or video, an attacker can imitate a manager's or supplier's voice and face well enough to pass on a phone or video call, especially under time pressure. In early 2024, police in Hong Kong described a case in which an employee of a multinational company transferred large sums after a video conference in which the other participants, including a senior manager, were deepfakes. Protection: a rule that no payment, change of bank details or urgent transfer is approved on a call or message alone; confirmation through a separate channel you already know, such as a call back to the number on file, never the one given in the request; two people to approve payments above a threshold; a code word for genuine urgent requests if you want one; and staff who know they will be backed for slowing a payment down. No network sensor can tell a real voice from a fake one. NetSenX is not the answer here: it does not analyse calls or video, and it does not see payment instructions.
