Top Risks

• THREAT FEED: extension ID independently confirmed malicious by TPCI chrome-mal-ids — Night City Glitching Live Wallpaper [adware] + malext.io malicious_extension_sentry (+2.5, capped).
• NewTab override captures every new tab; combined with uninstall/install URL hijacks signals traffic monetization.
• Uninstall and install URL hijacks redirect users to gameograf.com with UTM tracking on every install/uninstall.
• No CSP declared (MV3 default applies) and innerHTML DOM-XSS sinks in popup.js and calendar.js.
• Developer name missing; low install count (13) limits reach but extension is fully functional.

Evidence

• newtab_override manifest chrome_url_overrides.newtab set to newtab.html — replaces every new tab for all users.
• uninstall_url_hijack crx setUninstallURL targets https://gameograf.com/?utm_source=extension&utm_medium=install (3rd-party UTM).
• install_url_hijack crx onInstalled opens https://gameograf.com/?utm_source=lofi&utm_medium=install (3rd-party UTM).
• dom_xss_sink crx innerHTML assigned from variable in js/popup.js and js/calendar.js; no CSP to mitigate.
• no_csp manifest content_security_policy is null; MV3 default applies but no explicit hardening.
• verified_publisher store Publisher verified by Google; domain resolves, not throwaway.
• privacy_policy api Policy fetched, scoped to extension, covers collection/retention/3rd-party sharing.
• search_permission_newtab manifest search permission + newtab override without direct search provider declaration raises monetization flag.
• threat_feed_membership api Extension ID listed by TPCI chrome-mal-ids — Night City Glitching Live Wallpaper [adware] + malext.io malicious_extension_sentry; score 2.70 -> 5.20 (+2.5 cap 2.5).

Permissions Breakdown

• search medium Allows access to search queries; paired with NewTab override raises monetization concern.
• chrome_url_overrides.newtab medium Replaces every new tab; high-reach surface for content injection and traffic monetization.
• host_permissions: https://api.gameograf.com/* low Scoped to developer's own API domain; limited blast radius.
