Top Risks

• THREAT FEED: extension ID independently confirmed malicious by TPCI chrome-mal-ids — Sukuna Madness Live Wallpaper + AI Extensions New Tab [adware] + malext.io malicious_extension_sentry (+2.5, capped).
• Privacy policy URL is unreachable (fetch_error); effective no-policy treatment — score 10.0.
• NewTab override + uninstall/install URL hijack to gameograf.com UTM tracking — monetization shell pattern.
• Uninstall and install URL hijack both fire to 3rd-party domain with UTM parameters.
• dom_sink_innerhtml_userctrl in popup.js and calendar.js with no CSP — elevated DOM-XSS risk.

Evidence

• privacy_policy_unreachable api Fetch failed (ConnectionError) for https://api.gameograf.com/gameograf-privacy-policy.html; treated as no policy.
• newtab_override manifest chrome_url_overrides.newtab = newtab.html; replaces every new tab for user.
• uninstall_url_hijack crx setUninstallURL → 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_sink crx innerHTML assigned from variable in popup.js and calendar.js; no CSP to mitigate.
• no_developer_name store developer_name field is empty string; low accountability.
• verified_publisher store Extension carries verified_publisher=true via gameograf.com; domain age 2051 days.
• csp_absent_mv3 manifest content_security_policy is null; MV3 strict default applies but no explicit CSP declared.
• threat_feed_membership api Extension ID listed by TPCI chrome-mal-ids — Sukuna Madness Live Wallpaper + AI Extensions New Tab [adware] + malext.io malicious_extension_sentry; score 5.17 -> 7.67 (+2.5 cap 2.5).

Permissions Breakdown

• search medium Allows reading/manipulating search provider; medium risk for a NewTab extension.
• 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/data-collection surface.
