What our analysis found
School Site Blocker showed no malicious code in Extension Auditor's review. Its permissions mean it can read and change data on all websites. It comes from a publisher with 14 extensions and was last updated in February 2026.
Analyst notes
The extension contains only 4 files (,,,) with 44 lines of straightforward JavaScript. The reads site-block rules from managed storage (enterprise-deployed config) and uses declarativeNetRequest to redirect those URLs — this is exactly the stated purpose of a school Chromebook site blocker. No data is exfiltrated, no remote code is loaded, no obfuscation is present, and no third-party destinations are contacted. The ML low score (0.04) correctly reflects benign behavior; the risk engine's 'High' rating is entirely driven by the broad host permission, which is architecturally required for a URL-redirect tool. The publisher's 60% malware rate on other extensions is a mild concern but does not override clean source code evidence here.
