Top Risks

• THREAT FEED: extension ID independently confirmed malicious by TPCI chrome-mal-ids — Dandadan Okarun Dark Mode Live Wallpaper [adware] + malext.io malicious_extension_sentry (+2.5, capped).
• NewTab override replaces every new tab page — primary search-monetization surface with uninstall/install URL hijacks.
• Privacy policy is Google's generic account policy (scope_extension=false, data_collection=true, third_party_sharing=true) — worst-case privacy disclosure.
• Uninstall and install URL hijacks redirect to gameograf.com with UTM tracking, signalling monetization intent.
• No CSP declared (MV3 default applies but csp_present=false); innerHTML DOM-XSS sink in popup.js increases risk.

Evidence

• newtab_override manifest chrome_url_overrides.newtab set to newtab.html — overrides every new tab page.
• uninstall_url_hijack crx setUninstallURL targets https://gameograf.com with UTM tracking params.
• install_url_hijack crx onInstalled opens https://gameograf.com with UTM install tracking params.
• generic_privacy_policy api Policy URL is Google's account policy; 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 guard.
• no_developer_name store developer_name is empty string; reduces accountability.
• stale_extension store 15 months since last update on active NewTab monetization extension.
• new_tab_monetization_shape manifest search permission + newtab override + install/uninstall URL hijacks = monetization shell pattern.
• threat_feed_membership api Extension ID listed by TPCI chrome-mal-ids — Dandadan Okarun Dark Mode Live Wallpaper [adware] + malext.io malicious_extension_sentry; score 5.44 -> 7.94 (+2.5 cap 2.5).

Permissions Breakdown

• search medium Allows reading/modifying search provider; relevant risk for a NewTab override extension.
• host_permissions: https://api.gameograf.com/* low Scoped to developer-controlled API domain; limited blast radius.
• chrome_url_overrides.newtab medium Replaces every new tab; primary monetization surface and search-redirect vector.
