The Technology Behind the Deception
For generations, we have relied on a fundamental truth: a familiar face and voice are reliable markers of identity. Artificial intelligence has shattered that certainty. The primary tools behind this disruption are voice cloning and deepfake videos. With
just a few seconds of audio from a social media post or a voicemail greeting, scammers can use AI to create a synthetic, yet terrifyingly accurate, clone of someone's voice. This cloned voice is then used to make urgent, panicked calls, often faking a car accident or a medical emergency to trick family members into sending money. Deepfakes take this a step further, using AI to generate or alter videos to make it appear as if someone is saying or doing something they never did. In one widely reported case, a finance employee transferred over $25 million after a video call with who he thought was his CFO and other colleagues; every person on the screen, except for the employee himself, was an AI-generated deepfake.
From Nuisance to National Threat
What was once the realm of science fiction is now a rapidly growing category of crime. In 2025, the FBI's Internet Crime Complaint Center began tracking AI-related fraud as its own category, logging over 22,000 complaints with losses nearing $900 million in that year alone. Experts agree this is likely an undercount, as many victims may not even realise the voice or video that tricked them was fake. These scams are not creating entirely new types of fraud; instead, AI is making old scams dangerously effective. The classic 'grandparent scam', where a fraudster pretends to be a grandchild in trouble, is now amplified by a perfectly cloned voice. Business Email Compromise (BEC) attacks, which used to rely on spoofed email addresses, can now be reinforced with a fake video call from the CEO. The result is that the usual red flags, like poor grammar or a sense of urgency, are no longer reliable indicators of a scam.
The New Rules of Trust
The core of the issue is that AI has made impersonation cheap, fast, and scalable. Scammers can now produce high-quality fake content in bulk, removing the human errors that used to give them away. This means our instincts are no longer enough. Hearing a voice you recognise is not sufficient proof of identity. Seeing a face on a screen is not definitive confirmation. The new paradigm requires a shift in behaviour from 'trust, but verify' to 'verify, then trust'. The very tools we use to connect with each other—social media videos, public speeches, online profiles—provide the raw material for fraudsters to build their attacks. Because you can't simply 'cancel' your voice or face like a stolen credit card, the damage from this type of identity theft can feel particularly invasive and permanent.
How to Protect Yourself and Your Family
Protecting against AI impersonation doesn't require becoming a technology expert, but it does demand a new level of healthy skepticism. The most effective defence is to verify requests through a separate, trusted channel. If you get an urgent call from a loved one asking for money, hang up and call them back on their known phone number. If it's a message from a boss asking for a wire transfer, contact them via an internal company chat or walk over to their desk. Many families are now adopting a 'safe word' or a secret question that only they would know the answer to. When an emergency call comes in, you can ask for the code word to confirm the caller's identity. Finally, be mindful of what you share online. While it's difficult in our connected world, making social media profiles private can limit the amount of audio and visual data available for scammers to use against you.
