What our analysis found

J2TEAM Security, used by 300,000 people, showed no malicious code in Extension Auditor's review. Its permissions mean it can inject scripts into pages and can observe network requests. It comes from a trusted publisher and was last updated in May 2026.

Analyst notes

The extension is a long-established, popular, and well-reviewed security tool whose functionality (anti-phishing, privacy controls, Facebook utilities) aligns with its declared purpose. All network communication is with the publisher's own domains ([domain withheld], [domain withheld]) or standard services (Facebook, Google) for anti-phishing and reporting. The 'critical' permissions are justified for its features and not abused. The ML model's high pattern counts originate from bundled third-party UI libraries (, Ant Design), not malicious code. The 0% malware rate in the permhash cluster and strong publisher reputation further corroborate a false positive.
