Top Risks

• THREAT FEED: extension ID independently confirmed malicious by TPCI chrome-mal-ids — Five Nights at Freddy's Live Wallpaper [adware] + malext.io malicious_extension_sentry (+2.5, capped).
• New-tab override + search permission: classic search-hijacking monetization shell pattern.
• Uninstall URL hijack redirects to chromewallpaper.com — monetization/tracking on removal.
• Install URL hijack opens chromewallpaper.com on install — onboarding traffic capture.
• Privacy policy is Google's generic policy (unscoped, admits data collection and 3rd-party sharing) — scores worst-case.
