Top Risks

• THREAT FEED: extension ID independently confirmed malicious by TPCI chrome-mal-ids — Barbarian Warrior Princess Live Wallpaper [adware] + malext.io malicious_extension_sentry (+2.5, capped).
• NewTab override with search permission creates monetization surface on every new tab opened.
• Uninstall and install URL hijack both redirect to gameograf.com marketing URL.
• Two innerHTML DOM-XSS sinks in popup.js and calendar.js with no CSP to mitigate.
• No developer name listed; verified publisher but empty 'Offered by' field reduces accountability.

Evidence

• newtab_override manifest chrome_url_overrides.newtab set to newtab.html; search permission also declared — monetization shape.
• uninstall_url_hijack crx setUninstallURL targets https://gameograf.com/?utm_source=extension&utm_medium=install
• install_url_hijack crx onInstalled opens https://gameograf.com/?utm_source=extension&utm_medium=install
• dom_xss_sinks crx innerHTML assigned from variable in js/popup.js and js/calendar.js; no CSP present to block exploitation.
• no_csp manifest content_security_policy is null; MV3 default applies but no explicit hardening.
• verified_publisher store verified_publisher == true; domain gameograf.com resolves and is not throwaway.
• privacy_policy api Policy fetched, scoped to extension, documents collection/retention/third-party sharing — adequate.
• empty_developer_name store developer_name is empty string despite verified publisher status; reduces accountability signal.
• threat_feed_membership api Extension ID listed by TPCI chrome-mal-ids — Barbarian Warrior Princess Live Wallpaper [adware] + malext.io malicious_extension_sentry; score 3.34 -> 5.84 (+2.5 cap 2.5).

Permissions Breakdown

• search medium Allows querying search provider; relevant for NewTab override monetization shape.
• host_permissions: https://api.gameograf.com/* medium Scoped to developer domain; used for wallpaper/config API calls.
• chrome_url_overrides.newtab medium Replaces new-tab page; high-frequency touch-point enabling search monetization.
