Picture Musa in Kaduna, closing his shop for the evening. A WhatsApp voice note arrives from his uncle’s number. The voice is unmistakable, the same deep laugh, the same “my son”. His uncle says he has been in an accident on the Abuja road and needs ₦150,000 sent to a nurse’s account right now. Musa’s hands shake as he opens his banking app. Then he pauses and calls his uncle directly. His uncle picks up, calm, at home watching the news. The voice note was fake. AI scams in Nigeria are getting this convincing, and this guide will help you and your family spot them.
AI scams are frauds that use artificial intelligence to trick people, for example by cloning a loved one’s voice, creating fake videos (deepfakes) of trusted people, or writing flawless fake messages. The best defence is simple: pause, verify through a separate channel you already trust, and agree a family “safe word” for emergencies.
Key takeaways
- Scammers can clone a voice from a short audio clip, often taken from social media.
- A familiar voice or face is no longer proof of identity on its own.
- Always call back on a number you already know, not the one that contacted you.
- A family safe word and a “pause before paying” rule stop most AI scams.
How AI changed scams
Old scam messages were often easy to spot: bad grammar, strange requests and obvious lies. AI has removed many of those clues.
| AI trick | What it does | Example |
|---|---|---|
| Voice cloning | Copies someone’s voice from a short recording | A voice note from “your mum” asking for urgent money |
| Deepfake video | Creates fake video of a real person | A “celebrity” or “pastor” video promoting an investment |
| AI-written messages | Writes perfect, personalised emails and chats | A job offer or “bank” email with no spelling mistakes |
| Fake websites and chatbots | Builds convincing online shops and support bots | A fake store with AI-made product photos and reviews |
The US Federal Trade Commission warned as early as 2023 that scammers can clone a loved one’s voice using a short audio clip and a voice-cloning program, then use it in “family emergency” scams. BusinessDay has also reported on AI-powered job, tech support and online shopping scams targeting Nigerians.
8 warning signs of an AI scam
- Extreme urgency. “Send it now or something terrible will happen.”
- Secrecy. “Don’t tell anyone else in the family.”
- A new account number. The money must go to a stranger, a “nurse”, a “lawyer” or a “police officer”.
- Voice notes instead of calls. The person won’t pick up a live call or video call.
- Odd details. The voice sounds right but uses words or names your relative never uses.
- Video that looks slightly off. Strange blinking, lips out of sync with words, blurry edges around the face.
- Investment promises from famous faces. Celebrities, politicians and religious leaders “endorsing” quick-profit schemes.
- Unusual payment methods. Requests for crypto, gift cards or airtime.
Simple verification habits that stop AI scams
1. Pause
Scammers want you to panic. Take two minutes before you send money or share any details, no matter how urgent it sounds.
2. Call back on a number you trust
Hang up and call the person directly using the number saved in your phone, or call another family member who is with them. Don’t use a number given in the message.
3. Use a family safe word
Agree a secret word or question with close family that only you know. Never post it online. If someone calls with an emergency and can’t give the safe word, treat it as a scam.
4. Ask a personal question
Ask something only the real person would know, such as the name of your childhood street or what you ate at the last family gathering.
5. Limit your voice and video online
Consider making your social media accounts private and being careful about posting long voice notes or videos publicly. Read our guide on online privacy and the NDPA.
Teaching parents and older relatives without shaming them
Older relatives are often targeted because they are trusting and less familiar with AI. Anyone can be fooled, including young, tech-savvy people. Here is a respectful way to help:
- Explain it as news, not a lecture: “Mummy, there’s a new trick where thieves copy people’s voices.”
- Agree your family safe word together, in person or on a call.
- Save important numbers clearly in their phone, so they can always call back.
- Tell them they can always call you before sending money, with no judgement.
- Share this article in your family WhatsApp group.
What to do if you already sent money
- Call your bank immediately and report the transfer as fraud. Ask if it can be stopped or reversed.
- Change passwords and secure your accounts if you shared any login details or codes.
- Keep evidence: voice notes, screenshots, phone numbers and account numbers.
- Report it to the police and to the EFCC.
- Warn your family and friends so the scammer can’t use the same trick on them.

Frequently asked questions
Can scammers clone someone’s voice?
Yes. The US Federal Trade Commission has warned that scammers can copy a person’s voice using a short audio clip, often taken from social media, and a voice-cloning program. That is why a familiar voice alone is no longer proof that a call or voice note is real.
How can I tell if a video is a deepfake?
Look for lips that don’t match the words, unnatural blinking, blurry edges around the face, odd lighting and a flat or robotic voice. But deepfakes are improving, so the safest approach is to verify the claim through official channels rather than trying to judge the video alone.
What should I do if I sent money to a scammer?
Contact your bank immediately to report the fraud and ask whether the transfer can be stopped. Secure your accounts, keep all evidence, and report the scam to the police and the EFCC. Warn your family and friends so they don’t fall for the same trick.
Final thoughts
AI has made scams sound and look more real, but the oldest defence still works: pause and verify. Call back on a number you trust, use a family safe word and never let urgency push you into sending money. Share these habits with the people you love. The five minutes you spend today could protect them tomorrow.
