What our analysis found

Ad Remover - Ad Blocker for Chrome, used by 200,000 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 inject scripts into pages.

Key findings

  • High

    Other

    The bundled uses manifest_version 2 with webRequest and webRequestBlocking permissions, but the published Chrome Web Store listing shows manifest_version 3 with declarativeNetRequest, declarativeNetRequestFeedback, activeTab, and scripting permissions. This discrepancy may indicate a version mismatch between the reviewed bundle and the live listing, but does not by itself indicate malicious intent.

Analyst notes

The extension is an ad blocker based on uBlock Origin with added premium prompt features. The permissions are standard for ad blockers. The overlay frames track user interactions (e.g., trial status, link clicks) but this is disclosed as 'User activity' in the CWS listing and data likely goes to the publisher's own domain ([domain withheld]). No evidence of unauthorized external data exfiltration or malicious code injection. The ML model likely flagged the extension due to broad permissions and common ad-blocker code patterns.
