 "notes": "Measurement study by SentinelLABS with Censys, not an incident - class research_demo and impact_realized false. It matters here because it sizes the target surface that NadMesh and LLMjacking actually monetise, and because tool-calling turns an exposed text endpoint into an exposed action endpoint. The Hacker News writeup additionally attributes an 'Operation Bizarre Bazaar' LLMjacking marketplace to this research; that name does not appear in the SentinelLABS post cited here, so that claim is unverified.",
