What is a deepfake? AI-generated video and audio in fraud

Synthetic video, audio or images, made with AI, that show a real person saying or doing something they did not. Criminals use deepfakes to impersonate executives, officials and relatives.

How it works

The FBI warns that criminals use generative AI to make fraud more believable and to reach more people with less effort. Its December 2024 warning lists AI-generated images, audio and video, including short audio clips that impersonate a relative in a crisis and videos that depict public figures.

A real example

The same FBI warning says criminals generate videos for real-time video chats with alleged company executives, law enforcement or other authority figures. In May 2025 the FBI warned of a campaign using AI-generated voice messages that claimed to come from senior US officials.

How to train for it

  • Agree a verification step for unusual requests, such as a call back on a known number.
  • Look for the imperfections the FBI lists: irregular faces, inaccurate shadows, lag time, voice matching and unrealistic movements.
  • Remember that a familiar face or voice is no evidence of identity.

SecurityRing’s deepfake training puts a deepfake video of one of your own leaders, made with their consent, inside a phishing simulation email. Each leader approves it through a private link, and you review a watermarked preview first.
