Top Risks

• THREAT FEED: extension ID independently confirmed malicious by TPCI chrome-mal-ids — Kakashi Hatake with Blue Glowing Eyes Live Wallpaper [adware] + malext.io malicious_extension_sentry (+2.5, capped).
• Google's generic privacy policy used — does not scope to this extension; classified as data_collection+third_party_sharing with no extension scope (Privacy +10).
• NewTab override with search permission and both install/uninstall URL hijacks to gameograf.com — monetization shell pattern.
• Uninstall and install URL hijacks confirmed: tracks user installs/removals via UTM-tagged redirects.
• Two DOM-XSS innerHTML sinks (popup.js, calendar.js) with no CSP — elevated XSS risk if data from api.gameograf.com is unsanitized.

Evidence

• newtab_override manifest chrome_url_overrides.newtab set to newtab.html — replaces every new tab page.
• 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=lofi&utm_medium=install
• privacy_policy_generic api Policy URL is Google's own account policy; scope_extension=false, data_collection=true, third_party_sharing=true.
• dom_xss_sink crx innerHTML assigned from variable in popup.js and calendar.js; no CSP present (MV3 but csp_present=false).
• no_developer_name store developer_name is empty string; reduces accountability.
• verified_publisher store Verified publisher badge present for gameograf.com; domain resolves, not throwaway.
• search_permission_newtab manifest search permission combined with newtab override typical of search-monetization pattern.
• threat_feed_membership api Extension ID listed by TPCI chrome-mal-ids — Kakashi Hatake with Blue Glowing Eyes Live Wallpaper [adware] + malext.io malicious_extension_sentry; score 4.61 -> 7.11 (+2.5 cap 2.5).

Permissions Breakdown

• search medium Allows reading/manipulating search queries; paired with newtab override increases 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 every new tab; prime real estate for ad-monetization and search hijacking.
