Deepfake and AI fraud: when you can’t trust your eyes or ears

Cloned voices and fake video calls are being used to authorise payments and fool families. Process beats perception.

What it is

AI-enabled fraud uses generated voices, faces, video and text to impersonate real people — a CEO, a colleague, a relative — or to create fake identities and documents that pass basic checks.

How it works

  1. Criminals collect public audio and video of the person they want to copy.
  2. AI tools clone the voice or face, sometimes in real time.
  3. The victim gets a call, voice note or video meeting that seems genuine.
  4. An urgent, confidential request follows: a payment, a password, a data transfer.

Red flags

  • Urgency plus secrecy, even from someone you know.
  • A request to bypass normal approval steps.
  • Slight delays, odd lighting or audio glitches on a video call.
  • A family member in trouble who can’t be reached any other way.

A real-world example

In 2024, an employee at engineering firm Arup in Hong Kong transferred around US$25 million after a video call in which the CFO and colleagues were all deepfakes.

How to protect yourself

  • Verify unusual requests through a separate channel you already know.
  • Agree a family “safe word” for emergencies.
  • Require two-person approval for new payees and large payments at work.
  • Limit how much voice and video of executives is publicly available where possible.

If it happened to you

  • Call your bank now using the number on your card. Speed is the biggest factor in getting money back.
  • Stop all contact with the scammer and don’t send more money — including “fees” to recover losses.
  • Keep evidence: screenshots, numbers, emails, transaction references.
  • Report it to the police and your national fraud reporting service.

The rules

Laws are catching up: the EU AI Act sets transparency duties for deepfakes, and payment regulators increasingly expect firms to detect AI-generated identity documents during onboarding.
