TL;DR: AI-generated audio and video can now impersonate real people closely enough to drive fraudulent wire transfers or credential capture, and Doppel says one documented 2024 incident produced a major loss before the request was verified. Media cues still help, but out-of-band verification is becoming the control that matters most.
Editorial analysis by NHI Mgmt Group, based on content published by Doppel: “How to Detect Deepfakes: Visual, Audio & Technical Red Flags”.
Key questions
Q: What breaks when organisations trust live video for approval decisions?
A: The approval process starts using appearance as proof of identity, which is exactly what deepfake attackers exploit.
Q: Why do deepfake attacks create such high risk in finance and access workflows?
A: Deepfakes create risk because they compress the attacker’s cost, skill, and time requirements while exploiting human trust in familiar voices and faces.
Q: What are the warning signs that a request may be a deepfake impersonation attempt?
A: Watch for urgent or secretive instructions, unfamiliar numbers or devices, requests to switch channels, flat emotional delivery, unnatural silence, or claims that need immediate action.
Practitioner guidance
- Implement out-of-band verification for high-risk approvals Require a separate trusted channel for wire transfers, credential resets, privileged access approvals, and urgent exceptions.
- Restrict what can be approved from live calls Block final approval of payments, MFA resets, or admin changes when the request arrives only through video or voice.
- Train staff to treat urgency as a verification trigger Teach finance, help desk, and executive support teams that secrecy, pressure, and off-process requests are social engineering signals.
Bottom line: Deepfake impersonation undermines human recognition as a security control, especially when the request carries urgency or authority.
