What our analysis found

Screencastify - Screen Video Recorder, used by 9,000,000 people, showed no malicious code in Extension Auditor's review. Its permissions mean it can read and change data on all websites and can inject scripts into pages. It comes from a trusted publisher and was last updated in October 2026.

The extension is a well-known screen recorder (Screencastify) with 10M+ users and a verified publisher. The provided source files (HTML pages, FFmpeg and MediaPipe WASM loaders, Pendo guide CSS, mouse tracker) show no malicious behavior, data exfiltration, or unauthorized collection. All network destinations (,, Google Fonts) are first-party or standard CDNs consistent with the extension's purpose. The broad permissions are required for capture and content script integrations, and the disclosed data practice (Personally identifiable information) aligns with the extension's SaaS model. The ML model likely overfitted on permission patterns and minified bundle statistics, which are typical for large production extensions.
