A Japanese city posted AI-generated images of bear encounters as official warnings to the public. The images depicted bears in situations that appeared to be real photographs. The posts caused public alarm and misinformation about bear sightings in the area.

Reported impact

The fake bear warning images caused panic among residents. Members of the public were misled into believing genuine bear encounters had occurred based on the AI-generated imagery.

Index analysis

Governance controls
