In code review (v8.11.5)

Our reviewer read version 8.11.5 — the most recent version we have reviewed — and found no malicious behaviour. The version shown here has not been individually reviewed yet.

What our analysis found

YouBoost - VPN for YouTube. Unblock YouTube. VPN for browser, used by 2,000,000 people, showed no malicious code in Extension Auditor's review. Our code review reported 1 finding (1 high), led by other. Its permissions mean it can read and change data on all websites and can observe network requests.

Key findings

  • high· other —The bundled manifest does not include the host_permission that appears in the live Chrome Web Store listing. This mismatch could indicate an undisclosed data collection endpoint added in a later version, or a planned update not yet reflected in the bundled ZIP.

The extension is a VPN tool for YouTube; broad permissions (proxy, webRequest, etc.) are essential for its core functionality. Review of the provided content scripts shows only intended UI customization and no unauthorized data exfiltration. The manifest mismatch with the CWS listing (missing a Sentry host_permission entry) is minor and likely due to a version difference, not indicative of malice.
