A finance employee at engineering firm Arup joined a video call with who appeared to be the company’s CFO and several colleagues. Every face on the call was a deepfake. Over 15 transfers, the employee authorised roughly 25 million dollars. That single incident, from Arup’s Hong Kong office, is now one line item in a fraud category that a 2026 Surfshark study puts at 3.7 billion dollars in publicly documented losses worldwide, the current figure at the time of publishing, and that figure almost certainly understates the real total.
A Genuinely Global Fraud Category
The Surfshark research, drawing on the AI Incident Database, Resemble.AI and OECD records, breaks the losses down by country rather than treating this as one region’s problem. The United States accounts for 712 million dollars, 43 per cent of it corporate. Malaysia reports 502 million dollars, driven largely by investment scams. Hong Kong sits at 229 million dollars. Indonesia’s losses come almost entirely from fraudulent loan applications. The United Kingdom reports 149 million dollars, much of it celebrity-impersonation investment scams. No single region owns this problem, and the methods vary by market as much as the targets do.
The Real Number Is Almost Certainly Higher
The study’s authors flag a specific limitation worth taking seriously: fewer than 5 per cent of voice-clone fraud victims ever report their losses. That means 3.7 billion dollars is a floor, not a ceiling, built entirely from cases that became public. For every Arup, a large, sophisticated organisation with the resources to disclose and investigate publicly, there are almost certainly dozens of smaller incidents that never surface in any database.
When the Defence Actually Worked
Not every attempt succeeds, and the near-misses are instructive. At LastPass, an employee received what sounded like a deepfake audio call from the CEO over WhatsApp and grew suspicious specifically because the channel itself was unusual, a legitimate CEO request would not normally arrive that way. That single procedural instinct, noticing the wrong channel rather than scrutinising the voice, stopped the fraud. It is a reminder that detecting deepfakes technically is often less reliable than training people to notice when a request arrives through an unexpected route or bypasses a normal approval step.
What This Means for Finance and PMO Controls
The Arup case succeeded because a live video call was treated as sufficient authorisation on its own for a high-value transfer. That control gap exists in most organisations, a request that looks and sounds right, delivered through what appears to be the normal channel, still gets treated as verified. The practical fix does not require deepfake-detection software as a first line of defence. It requires a callback protocol for any high-value transfer request, verified through a separate, previously agreed channel, regardless of how convincing the original request appeared. A PMO or finance transformation programme introducing new payment or approval workflows should build that callback step into the process design itself, rather than leaving it as a training slide nobody reviews again after induction.
