AI-enabled impersonation scams are no longer a merely theoretical concern.

Judged as of 2025-09-11. True: credible reports from before that date (law enforcement or regulator warnings such as FBI or FTC alerts, court cases, or reputable news investigations) document real scams in which AI-generated voice, video or text impersonating a real person was used to defraud victims. Mostly true: such real incidents are documented, but only in a few cases or with some uncertainty about whether AI was used in a given case. Mixed: there are only scattered, unverified reports, and authorities still describe the threat mainly as emerging. Mostly false: the documented cases turn out on inspection mostly to be demonstrations, research or hypothetical warnings, with almost no confirmed real-world scams. False: no AI-enabled impersonation scam had actually happened by that date, and authorities treated the risk as purely theoretical.

Set before the research began.

3. E3 Scammers use AI to enhance their family emergency schemes US Federal Trade Commission (Consumer Advice) · 17 March 2023

   “Artificial intelligence is no longer a far-fetched idea out of a sci-fi movie. We're living with it, here and now.”

4. E4 Arup employee falls victim to US$25 million deepfake video call scam Construction Briefing · 21 May 2024

   “Engineering firm Arup has confirmed that one of its employees in Hong Kong fell victim to a deepfake video call that led them to transfer HK$200 million (US$25.6 million) of the company’s money to criminals.”

An FBI IC3 public service announcement from December 2024 (E1) lists criminals using AI-generated audio clips to impersonate people and get into their bank accounts as an observed technique, not a hypothetical one. CNN (E2) and Construction Briefing (E4) report that Arup confirmed one of its employees was defrauded of about US$25.6 million through a video call with deepfake re-creations of the firm's executives. The FTC alert (E3) also says AI is in use now in family emergency scams. Together these sources from before 2025-09-11 show real AI-enabled impersonation scams had taken place, which meets the "true" criterion.
