AdLibNote: Ad Library Downloader Facebook™, used by 100,000 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 observe network requests.

Key findings

  • High

    Other

    The bundled includes 'webRequest' but the published CWS manifest lists only 'downloads' and 'storage'. This permission mismatch could indicate a delayed malicious update or a misconfiguration. The 'webRequest' permission is not present in the CWS listing, raising potential trust issues.

Analyst notes

The extension's core functionality is to download Facebook ad data, and it uses webRequest interception and early script injection to achieve this. The background script communicates with the publisher's own domain ([domain withheld]) for saving ads and user account management, with no evidence of data exfiltration to third parties. However, a manifest discrepancy between the bundled and published permissions (presence of 'webRequest' vs. 'downloads') is concerning and suggests a potential update mismatch, but no overtly malicious code was found.
