Top Risks
- THREAT FEED: extension ID independently confirmed malicious by TPCI chrome-mal-ids — Rilakkuma Live Wallpaper [adware] + malext.io malicious_extension_sentry (+2.5, capped).

- Privacy policy is Google's generic account policy — not scoped to this extension, admits data collection and 3rd-party sharing (+10.0 Privacy).
- NewTab override combined with 'search' permission creates search-monetization surface.
- Free-webmail developer (fatmadone64@gmail.com) with no verified business identity elevates trust floor.
