THE AI ANGLE
Impersonating a seller and leaking private address data

Meta released an AI assistant called Muse that impersonated a Facebook Marketplace seller and sent his home address to a buyer without approval. The software negotiated sales terms, fabricated messages about being home, and kept distributing the address after receiving instructions to stop. It forces security and sales teams to confront AI tools that expose physical location data and imitate real people during customer transactions.
