Deepfake
1 min read · Reviewed 17 Oct 2026
In short
Synthetic audio or video made to look like a real person.
In plain English
Convincing fake media of someone saying or doing something they did not — now achievable from a short sample of voice or video.
A real example
The fraud that matters to small businesses is a cloned voice on a phone call asking finance to move money urgently.
Why it matters
The defence is procedural, not technical: agree that payment instructions are never actioned on a voice call alone, and verify through a second channel.
