Top Risks

• THREAT FEED: extension ID independently confirmed malicious by TPCI chrome-mal-ids — Deku And Shigaraki Wallpaper [adware] + malext.io malicious_extension_sentry (+2.5, capped).
• Privacy policy is Google's own policy — not scoped to this extension, admits data collection and 3rd-party sharing (+10 privacy pillar).
• Uninstall and install URL hijacks redirect to gameograf.com for monetization tracking (+3.0+2.0 webstore).
• NewTab override with search permission creates search-monetization shell pattern (+2.0 webstore).
• No developer name listed; verified publisher but no 'Offered by' display name increases reputation risk.

• chrome_url_overrides.newtab medium Replaces new-tab page; standard for category but enables search monetization.
