Top Risks

• THREAT FEED: extension ID independently confirmed malicious by TPCI chrome-mal-ids — Anime Boy Meadow Butterfly Wildflower Lve Wallpaper [adware] + malext.io malicious_extension_sentry (+2.5, capped).
• Google's generic privacy policy used — does not scope to this extension; admits data collection and 3rd-party sharing (Privacy pillar max).
• Uninstall URL hijack redirects to gameograf.com UTM page; install URL hijack opens Stranger Things promo page (+3.0+2.0 Webstore).
• NewTab override with search permission and no CSP — classic monetization shell pattern.
• No developer name disclosed; blank 'Offered by' field raises accountability concerns.
