Top Risks

• THREAT FEED: extension ID independently confirmed malicious by TPCI chrome-mal-ids — Lofi Sytle Satoru Gojo Live Wallpaper [adware] + malext.io malicious_extension_sentry (+2.5, capped).
• Privacy policy is Google's generic policy (scope_extension=false, data_collection=true, third_party_sharing=true) — not scoped to this extension at all.
• NewTab override combined with install/uninstall URL hijack to gameograf.com — monetization shell pattern.
• Both install and uninstall URL hijacks fire to developer domain with UTM tracking parameters.
• Two innerHTML-from-variable DOM-XSS sinks (popup.js, calendar.js) with no CSP present.

Evidence

• newtab_override manifest chrome_url_overrides.newtab set to newtab.html — replaces 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
• generic_privacy_policy api PP 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 js/popup.js and js/calendar.js with no CSP.
• no_csp manifest content_security_policy is null; MV3 defaults apply but no explicit policy declared.
• verified_publisher store verified_publisher=true on support@gameograf.com; domain resolves, not throwaway.
• no_developer_name store developer_name is empty string; reduces accountability signal.
• threat_feed_membership api Extension ID listed by TPCI chrome-mal-ids — Lofi Sytle Satoru Gojo Live Wallpaper [adware] + malext.io malicious_extension_sentry; score 4.55 -> 7.05 (+2.5 cap 2.5).

Permissions Breakdown

• search medium Allows reading/modifying search queries; relevant for NewTab/search-override pattern.
• 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 vector for this category.
