Top Risks

• THREAT FEED: extension ID independently confirmed malicious by TPCI chrome-mal-ids — Sunrise Drive Live Wallpaper [adware] + malext.io malicious_extension_sentry (+2.5, capped).
• Privacy policy is Google's generic policy — not scoped to this extension; admits data collection and 3rd-party sharing (Privacy +10).
• NewTab override with uninstall URL hijack and install URL hijack both pointing to gameograf.com — monetization shell pattern.
• No CSP declared (MV3 default helps, but no explicit policy) combined with innerHTML DOM-XSS sink in popup.js.
• Extension stale 15 months; verified-publisher discount capped at -1.0 per v3.5 invariant 0c (stale > 18mo close, plus generic policy).

Evidence

• newtab_override manifest chrome_url_overrides.newtab set to newtab.html — replaces new-tab page for all users.
• uninstall_url_hijack crx Uninstall URL redirects to gameograf.com with UTM tracking params — monetization/telemetry on removal.
• install_url_hijack crx Install URL redirects to gameograf.com with UTM tracking params — install-time tracking.
• generic_privacy_policy store Privacy policy URL is Google account policy; scope_extension=false, data_collection=true, third_party_sharing=true.
• dom_xss_sink crx innerHTML assignment from variable in js/popup.js — DOM-XSS risk, no CSP guard.
• no_developer_name store developer_name is empty string in store listing.
• stale_extension store Last updated June 2025 but months_since_update=15 indicates ~15 months since prior update cycle.
• verified_publisher store Extension has verified publisher badge for gameograf.com; domain resolves and not throwaway.
• threat_feed_membership api Extension ID listed by TPCI chrome-mal-ids — Sunrise Drive Live Wallpaper [adware] + malext.io malicious_extension_sentry; score 5.59 -> 8.09 (+2.5 cap 2.5).

Permissions Breakdown

• search medium Allows querying the browser's search engine; relevant to NewTab/search monetization.
• host_permissions: https://api.gameograf.com/* low Scoped to developer's own API domain; limited blast radius.
• chrome_url_overrides.newtab medium Replaces the new-tab page; monetization vector and search-redirect risk.
