What our analysis found

Mochi Dictionary Extension, used by 90,000 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 September 2026.

All network requests go to first-party domains () for dictionary, account sync, and subtitle detection; permissions are used for injected UI, subtitle detection on, and cookie-based auth, fully consistent with the disclosed 'Personally identifiable information' collection and privacy policy. No third-party exfiltration, no obfuscation, and no unauthorized data collection observed.
