What our analysis found

Key findings

  • High

    Other

    Bundled manifest uses manifest_version: 2 and permission: <all_urls>, while the live CWS listing shows manifest_version: 3 with permissions activeTab and scripting. This discrepancy may indicate an unreviewed code change or a delayed-malicious update not present in the provided source.

Analyst notes

The extension code is minimal and performs only video playback rate adjustments with no data collection or remote communication. However, the bundled manifest differs from the published manifest (v2 vs v3, <all_urls> vs), which could indicate a delayed-malicious update not present in the provided source. The ML model's low risk score aligns with the benign code, but the manifest mismatch raises suspicion.
