A 419 scam is advance-fee fraud: the victim is promised a large sum of money but must first pay “fees” that the scammers simply keep.
How a 419 scam works
The name comes from section 419 of the Nigerian Criminal Code, which covers obtaining property by false pretences. The classic scheme started with letters and faxes in the 1980s and moved to e-mail in the 1990s (“Nigerian prince” messages). The pattern is always the same:
- the victim is offered a share of an inheritance, lottery win, frozen bank account or business deal;
- the scammer builds trust with fake documents, official-looking seals and urgent deadlines;
- before the money can be “released”, the victim must pay taxes, legal costs or bribes – again and again;
- the promised money never arrives.
Why it matters for security
The crude letters are easy to laugh at, but the same advance-fee logic now drives much more convincing fraud: fake job offers, crypto “recovery” services, romance scams and fake investment platforms. Scammers use social media profiles, stolen identities and, increasingly, AI-generated voices and deepfake video calls. Victims are often targeted again by “recovery agents” who promise to get the lost money back – for a fee.
How to protect yourself
- Never pay money in order to receive money – this is the defining sign of the scam.
- Verify companies, lawyers and officials through contact details you find yourself, not those in the message.
- Be suspicious of secrecy, urgency and payment by gift cards, crypto or money transfer services.
- Report attempts to your national cybercrime unit (for example the FBI’s IC3 in the US) and warn relatives, especially older ones.
