What happened
A paid video cloned the voices of Medellin mayor Federico Gutierrez and Nubank founder David Velez to promote a platform asking for 300,000 peso deposits; Gutierrez denounced it on X as absolutely false.
Impact: Mayors of Cartagena and Monteria also impersonated; victim losses unknown.
Who triggered it
Actor: Unknown
Attribution: No attribution; Nu's CEO separately reported fake interviews imitating major media outlets.
Motive: Pyramid-style investment fraud.
How it happened
Attack vector: AI voice cloning over edited footage, distributed as sponsored content.
Root cause: Abundant public audio of officials and executives; weak ad vetting.
Timeline
- Gutierrez warns on X about the cloned video
- Nu CEO David Velez denounces wave of fake AI interviews
Response
Public warnings by the mayor and Nu; Colombia's Law 2502 of 2025 later added AI deepfakes as an aggravating factor for impersonation.
Current status: Unresolved
