Top Risks

• THREAT FEED: extension ID independently confirmed malicious by TPCI chrome-mal-ids — Dan Da Dan Opening Live Wallpaper [adware] + malext.io malicious_extension_sentry (+2.5, capped).
• NewTab override replaces every new tab — core monetization/search-hijack surface.
• Privacy policy is Google's generic policy (scope_extension=false, data_collection=true, third_party_sharing=true) — does not cover this extension.
• Uninstall URL hijack routes to developer site with tracking params; install URL hijack also fires.
• No CSP declared (MV3 default applies but no explicit policy) and innerHTML DOM-XSS sink present in popup.js.

Evidence

• newtab_override manifest chrome_url_overrides.newtab set to newtab.html — replaces every new-tab page.
• uninstall_url_hijack crx setUninstallURL to https://gameograf.com with UTM tracking params on removal.
• install_url_hijack crx onInstalled opens https://gameograf.com with UTM install tracking params.
• generic_privacy_policy api Policy URL is Google's account privacy page; scope_extension=false, data_collection=true, third_party_sharing=true.
• dom_xss_sink crx innerHTML assigned from variable in js/popup.js with no CSP to mitigate DOM-XSS.
• search_permission_newtab_combo manifest search permission + newtab override = classic search-monetization shell pattern.
• stale_extension store 15 months since last update; maintenance score elevated (6-12 mo band = +3.5).
• verified_publisher_capped store Verified publisher discount capped to -1.0 due to months_since_update=15 (>12 triggers cap).
• threat_feed_membership api Extension ID listed by TPCI chrome-mal-ids — Dan Da Dan Opening Live Wallpaper [adware] + malext.io malicious_extension_sentry; score 5.55 -> 8.05 (+2.5 cap 2.5).

Permissions Breakdown

• search medium Allows reading/modifying search provider; combined with newtab override raises monetization risk.
• host_permissions: https://api.gameograf.com/* low Scoped to developer's own API domain; limited blast radius.
• chrome_url_overrides.newtab medium Replaces new-tab page — primary monetization vector for wallpaper/newtab shells.
