What our analysis found

Checkbot: SEO, Web Speed & Security Tester 🚀, used by 70,000 people, showed no malicious code in Extension Auditor's review. Its permissions mean it can observe network requests. It comes from a trusted publisher and was last updated in January 2025.

Analyst notes

Background script performs simple navigation and message passing, no webRequest listeners implemented despite broad permissions (typical for SEO auditing tools). High CWS rating (4.9), 70k users, featured listing, and publisher trust strongly contradict ML risk signals. Manifest version mismatch between bundle (MV2) and published listing (MV3) is a non-malicious hygiene issue. not reviewed but overall behavior aligns with described developer tool functionality; no exfiltration or code injection found.
