The destination is a hardcoded ngrok tunnel unrelated to any registry or vendor infrastructure, and the beacon fires automatically without any caller action or opt-in. The package's own metadata describes it as a `Dependency Confusion to RCE` proof-of-concept, and the install-time callback carries the installer's internal hostname to an external third party.\n","id":"MAL-2026-16478","modified":"2026-09-23T14:14:28Z","published":"2026-09-23T14:14:28Z","references":[{"type":"PACKAGE","url":"https://www.npmjs.com/package/event-hunter/v/1.0.0"}],"schema_version":"1.7.4","summary":"Malicious code in event-hunter (npm)"}
