When AI becomes the scammer's weapon
You receive a voice call from your CEO asking you to urgently wire 15 millions de FCFA to a supplier account. The voice is identical, the tone is familiar, the urgency feels real. You execute the transfer. Except it wasn't your CEO — it was an audio deepfake generated by artificial intelligence.
This scenario is no longer science fiction. In 2024, a Hong Kong company lost 25 million euros after an employee joined a video conference with deepfakes of his colleagues — all AI-generated. And Africa is not spared.
Deepfakes: what are we talking about?
A deepfake is content — audio, video, or image — generated or manipulated by artificial intelligence to realistically impersonate a real person. Current technologies make it possible to:
- Clone a voice from as little as 3 seconds of audio
- Create a video of someone saying things they never said
- Forge documents (ID cards, invoices, contracts)
- Spoof a face in real time during a video call
The most alarming part? The cost of such an attack has dropped below 50 euros, making this technology accessible to any scammer.
Africa on the front line
Widespread document fraud
In French-speaking Africa, 64% of rejected identity verifications result from AI-powered document manipulation. Automated tools allow attackers to reuse verified biometric data and take over accounts at scale.
Identity theft on social media
In Cameroon, ANTIC identified 8,499 fake accounts impersonating public figures and institutions. These fake profiles are used to defraud citizens and businesses by exploiting trust.
The CEO fraud, AI edition
CEO fraud — where someone impersonates a company executive to order a wire transfer — takes on a new dimension with deepfakes. In the past, a simple phone call could raise suspicion. Today, with a perfectly cloned voice, even the most vigilant employees can be fooled.
Types of deepfake scams targeting businesses
1. The fake executive call
An audio deepfake imitates the voice of the CEO or CFO to order an urgent wire transfer. The scammer typically calls at the end of the day or on a Friday, when alertness is lower.
2. The fake video conference
Real-time video deepfakes make it possible to stage fake meetings with "colleagues" or "partners" who don't exist. The goal: getting financial decisions approved.
3. Supplier fraud
An email paired with a perfectly forged invoice and a voice call from the "supplier" confirming a change in banking details. Everything looks legitimate — except the destination account.
4. Fraudulent recruitment
Deepfake candidates in video interviews to infiltrate companies and gain access to internal systems. This phenomenon is increasingly affecting tech companies.
How to protect yourself: 6 concrete measures
1. Dual validation protocol
No transfer above a certain amount should be executed based on a single communication channel. If the CEO calls about a wire transfer, call them back on their usual number to confirm.
2. Secret verbal passphrase
Establish a code word known only to those authorized to approve financial transactions. Change it regularly.
3. Training and awareness
Your teams need to know that deepfakes exist and that a voice call or video no longer proves someone's identity. Run simulations to test reflexes.
4. Clear communication policy
Establish in writing that never will an executive request an urgent transfer by phone or WhatsApp alone. Any financial request must go through official channels with written approval.
5. Document verification
For any invoice or document received by email, verify directly with the supplier through a separate channel. Compare with previous documents (typography, IBAN, format).
6. Detection tools
Software solutions are beginning to emerge to detect deepfakes in real time — analysis of visual artifacts, audio inconsistencies, suspicious metadata. The market is young but growing fast.
Warning signs to watch for
- Excessive urgency — "It needs to happen now, no time to wait"
- Change of banking details — especially when it's "temporary"
- Unusual call — an executive calling a bookkeeper directly, for example
- Emotional pressure — guilt-tripping, threats, extreme secrecy
- Slightly off audio/video quality — micro-glitches, lips not perfectly in sync
A global issue, local solutions
The United Nations sounded the alarm in March 2026, labeling deepfakes a threat to international security. But protection starts at the company level, with simple processes and a culture of verification.
Conclusion
AI is an extraordinary tool for businesses. But in the wrong hands, it becomes a formidable weapon. African SMEs, often less protected, are prime targets. The good news: the countermeasures are simple — dual validation, code words, training — and cost nothing.
