Protect the decision without needing to identify synthetic audio
A convincing voice or video can make an unusual request feel familiar. The FBI's 2024 generative-AI fraud notice describes synthetic audio and video used for impersonation. That supports taking verification seriously; it does not establish that a particular caller is AI-generated. A business can protect the requested transaction without solving the technical question of how the media was produced.
Focus on what the caller wants changed: a payment destination, an urgent transfer, a confidential document or an account recovery action. Keep that decision inside its normal approval process. Calling something a deepfake should not be necessary to pause an unverified instruction. The same control should work for ordinary human impersonation, a stolen account and a genuine person exceeding their authority.
Make the callback route independent of the incoming request
Use contact information already held in the organization's directory, supplier record or other established source. A new number introduced by the caller is part of the request under review. A second call to that new number does not create an independent check. If a known contact says their usual route has changed, verify the replacement through the existing change process before relying on it.
Confirm the exact proposed action rather than asking only whether the person called. Identity and authority are separate: a real colleague may not be authorized to alter a supplier beneficiary. Finance should be able to explain who confirmed the request, how the trusted contact was obtained and who approved release. Preserve the old approved details until the new instruction has passed that process.
Define what happens when the usual approver is unavailable
An absent owner is a predictable operating condition. Agree a deputy, a trusted route and a rule for holding a sensitive request when neither approver can be reached. Without this fallback, a caller can turn a normal absence into pressure to bypass the process. The fallback should be practical across the team's actual working hours and time zones.
Our request-verification protocol is a proposed operational aid. It does not claim to authenticate audio, score deepfake probability or guarantee a transfer is safe. Use it to identify where approval is missing and who owns the next decision. A senior-sounding request to keep the transaction secret should not remove the requirement for an authorized, recorded release.
| Decision point | Required route | If verification fails |
|---|---|---|
| Unexpected request | Pause the sensitive action and name it. | Do not release based on familiarity. |
| Caller identity | Return contact through an established route. | Keep the identity unverified. |
| Transaction authority | Check the person may authorize this change. | Escalate to the designated approver. |
| Beneficiary or recipient | Use the existing change-verification process. | Retain the previously approved information. |
| Approver unavailable | Use the pre-agreed deputy and trusted channel. | Hold until authority is available. |
| Already acted | Separate money, disclosure and account access. | Start each relevant response promptly. |
Use cues and shared secrets with clear limits
Odd timing, pressure and an unusual communication channel can justify additional checking. Their absence does not authorize a payment. Similarly, caller ID, a recognizable profile or a familiar face should not be treated as the transaction approval record. A team that relies entirely on spotting audio artifacts makes a sensitive financial decision depend on an uncertain visual or listening judgment.
If an organization uses a pre-agreed phrase, treat it as one limited check rather than the sole permission to release money. Do not disclose the phrase first, reuse account passwords as challenge words or record shared secrets in open channels. The established callback, the person's authority and the payment approval must still stand on their own. Review the process if a phrase may have been disclosed.
If someone complied, prioritize the affected action
A released transfer calls for prompt contact with the genuine bank or payment provider. An account code disclosed to the caller calls for the account owner's response. A document sent outside the organization needs a separate assessment of what it contained and who received it. Do not let a debate about whether the audio was synthetic postpone these practical decisions.
Preserve the available request, timestamps and known action history through the approved reporting route. Recording or sharing voice and video material may have privacy or legal implications, so do not start covert recordings as a universal rule. The organization should determine appropriate evidence handling and reporting for its circumstances and countries. Fraud recovery, attribution and the availability of specialist audio analysis cannot be promised here.
Rehearse a safe approval handoff
Practice with a written fictional scenario rather than cloning a colleague's voice. Ask the team where it would find a trusted number, who would approve a beneficiary change and what happens if the primary contact is unavailable. The result should be a corrected contact or approval process with an owner, not a list of people who failed to recognize an impersonation.
