Executive Summary

WebinarTV is a commercial service that exploits public Zoom meeting invites by secretly joining and recording meetings without participants' knowledge or consent. The service then publishes these recordings publicly on its platform. Unlike traditional recording methods that would trigger Zoom's intervention features, WebinarTV captures content through external recording, bypassing Zoom's built-in protections. This poses significant privacy and confidentiality risks for organizations conducting sensitive meetings, as any publicly-shared Zoom invite becomes a potential target. Organizations should implement strict meeting controls, use waiting rooms, require authentication for participants, and avoid sharing meeting links on public forums to mitigate exposure. Users should also be aware that public meetings may be recorded by third parties regardless of platform-level protections.

Summary

WebinarTV searches the internet for public Zoom invites, joins the meetings, secretly records them, and publishes (alternate link ) the recordings. It doesn’t use the Zoom record feature, so Zoom can’t do anything about it.
