What to do in the first hour after a deepfake payment fraud
Call the originating bank's fraud team as soon as anyone suspects the instruction was fake, using a phone number from the bank's website or your treasury agreement, never one from the suspicious thread. IC3's business email compromise guidance tells victims to contact the originating financial institution as soon as fraud is recognized and to ask for a recall or reversal, along with a Hold Harmless Letter or Letter of Indemnity.
Give the bank the transfer date, amount, sending account, beneficiary name, beneficiary bank and account number, and the payment reference. Ask what else they need and write down the name of the person you spoke to, the time and the case reference. Then file a complaint at ic3.gov with the same banking details; IC3 stresses that a complaint missing banking information is much harder to act on.
Nobody needs to settle whether the voice or face was synthetic before doing any of this. The transfer was unauthorized either way, and an hour spent debating the media is an hour the beneficiary has to move the funds onward.
- Phone the bank's fraud line and request a recall; confirm in writing.
- File the IC3 complaint with full beneficiary and transaction data.
- Hold any other pending payments to the same beneficiary or requested by the same person.
- Name one finance owner for recovery and one security owner for containment.
How much money can be recovered, and how fast?
Recovery is realistic when the report is fast. The FBI's 2024 Internet Crime Report says the IC3 Recovery Asset Team initiated the Financial Fraud Kill Chain on 3,020 complaints involving $848.4 million in attempted theft. It froze $469.1 million in domestic cases and $92.5 million in international ones, a 66% success rate, and most of those incidents were business email compromise.
The report's case examples show what timing looks like. In March 2024, FBI Denver handled a real estate fraud where victims wired $956,342 after a spoofed email; they noticed two days later, the Recovery Asset Team moved to freeze the recipient account, and $955,060 was returned. In a September 2024 case referred by the FBI's legal attaché in Singapore, a US bank froze $5.1 million of a $6.66 million transfer, but funds that had already been wired on to Spain and China were out of immediate reach.
| Measure | Domestic | International |
|---|---|---|
| Complaints worked | 2,651 | 369 |
| Funds frozen | $469.1 million | $92.5 million |
| Combined attempted theft | $848.4 million | Included in total |
| Overall success rate | 66% | 66% |
Preserving deepfake evidence without slowing the recall
Collect originals, not copies of copies. That means the meeting recording or platform export, the voicemail or call recording file, chat exports, emails with full headers, the invoice or bank-change letter, approval records from the payment system and the vendor master change history. Screenshots help explain the story but drop the metadata that investigators, insurers and your own forensic team will ask for.
Hash each original file, store it with restricted access, and keep one timeline that both finance and security write into. Note who received the request, which verification steps were done or skipped, what policy exception was used and when the payment was released. Write the timeline without assigning blame; the employee who approved the payment is usually your best witness.
If the attacker used a live video call, ask the meeting platform administrator to preserve logs and participant details quickly, because retention windows can be short. A recording made by the victim is still useful even if it is low quality.
Containing the compromised accounts and warning the next target
Assume the attacker still has a foothold. Review the mailboxes and collaboration accounts involved for forwarding rules, delegated access, new connected apps and recovery changes. Revoke sessions and reset credentials through a verified process, after the evidence above has been captured.
Search for sibling requests. Deepfake payment fraud often runs several attempts at once: other employees on the same call, other vendors receiving the same bank-change letter, or a second request queued for next week. Tell the impersonated executive or vendor through a known channel, and send approvers a short, specific warning naming the untrusted beneficiary, invoice or account and the only channel through which genuine changes will arrive.
Reporting duties for banks and companies
Every victim should file with IC3 and keep the complaint number alongside the bank reference. Banks and other US financial institutions have an extra step: FinCEN alert FIN-2024-Alert004, issued on 13 November 2024, asks them to include the key term FIN-2024-DEEPFAKEFRAUD in field 2 of a Suspicious Activity Report and in the narrative when the activity relates to deepfake media.
The same alert lists red flags worth reusing in a post-incident review. They include a customer switching communication methods during a live check after suspicious glitches, a third-party webcam plugin during live verification, and a photo or video flagged by commercial or open-source deepfake detection software. Insurance notification, data protection, sector regulators and listed-company disclosure rules may also apply; legal counsel should own that list.
Where deepfake detection fits in payment fraud response
During the incident, detection is supporting evidence. Running the preserved recording through a detector can help insurers, investigators and the post-incident review understand what happened, but recovery, reporting and containment should never wait for the result. A detector score is a probability, and your payment policy decides what happens with it.
Before the next incident, detection belongs at the moment money moves. NeuroVerify, Neural Defend's verification API, checks a face image, video or audio clip in one request across six signals, including Live Presence Verification, Face Manipulation Detection and AI Generative Model Analysis, and returns one risk score with signal-level evidence. The target is under 200 ms at p95 on eligible image requests, so a check can sit inside a high-value payment approval or a callback without adding noticeable delay.
On still images, Neural Defend ranked first of 36 systems on the public VendorBench-100 benchmark, with an MCC of 0.876 against 0.646 for the next vendor. That benchmark covers images only, not live calls or audio. For phone-based instructions, NeuroCall, currently in Beta, is the Neural Defend product built for voice deepfake detection. Neither replaces a callback to a known number or dual approval for new beneficiaries; they make it harder for a convincing face or voice to override those controls.
Evidence boundary
Limitations
- Recovery figures come from FBI IC3 cases reported in the US and do not predict the outcome of any individual transfer, especially cross-border ones.
- Reporting duties vary by country, sector and contract; this page covers US routes and is not legal advice.
- Deepfake detection gives a probabilistic signal; it does not prove who was behind an instruction and should not delay recall or reporting.
- VendorBench-100 measures still-image detection only and says nothing about live video calls, voice or latency in your environment.
