What our analysis found
Netcraft Extension, used by 60,000 people, showed no malicious code in Extension Auditor's review. Its permissions mean it can read and change data on all websites and can observe network requests. It comes from a trusted publisher and was last updated in February 2024.
The extension is a legitimate anti-phishing and malware blocker from Netcraft, a well-known security company. All permissions (<all_urls>, webRequest, webRequestBlocking, etc.) are essential for its stated purpose of scanning and blocking malicious URLs. All network requests go to Netcraft's own domains (,,), which are first-party and disclosed in the privacy policy. Data collection (web history, user activity, PII) is explicitly disclosed in the Chrome Web Store listing. No evidence of unauthorized data exfiltration, code injection, obfuscation, or third-party tracking was found. The ML model's low risk score (0.00) aligns with this clean review, while the third-party risk-score flagged permissions that are typical for security extensions.
