What our analysis found

Microsoft Defender Browser Protection, used by 3,000,000 people, showed no malicious code in Extension Auditor's review. It comes from a trusted publisher and was last updated in February 2025.

Analyst notes

The extension is a legitimate Microsoft Defender Browser Protection tool that checks URLs against Microsoft's SmartScreen API and blocks malicious sites. All network requests go to Microsoft-controlled domains ([domain withheld] for URL verification, [domain withheld] for telemetry), consistent with its purpose. The permissions (tabs, webNavigation, storage) are required for its monitoring and blocking functions. The code contains no obfuscation, injection, or data exfiltration to third parties. The manifest version discrepancy (bundled v2 vs. published v3) is likely due to the analysis bundle being outdated, and does not indicate malicious intent. The ML model's low risk score and clean permhash cluster support a benign verdict.
