Top Risks

• NewTab override with search permission — classic traffic/search monetization shell pattern.
• Uninstall and install URL hijack both point to gameograf.com tracking URL.
• No developer name listed; low-install tail extension with search override raises supply-chain concern.
• DOM-XSS sink (innerHTML) in calendar.js without CSP on MV3 extension.
• Privacy policy scoped but extension contacts google sub-services not declared in host_permissions.

Evidence

• newtab_override manifest chrome_url_overrides.newtab set to newtab.html — replaces every new tab page.
• uninstall_url_hijack crx setUninstallURL to https://gameograf.com/?utm_source=extension&utm_medium=install
• install_url_hijack crx onInstalled opens https://gameograf.com/?utm_source=extension&utm_medium=install
• no_developer_name store developer_name is empty string — no 'Offered by' identity.
• no_csp manifest content_security_policy is null; csp_present=false on MV3.
• dom_xss_sink crx innerHTML assigned from variable in js/calendar.js without sanitization.
• privacy_policy_scope api Policy fetched; scope_extension=true, data_collection=true, retention=true, third_party_sharing=true.
• low_installs_newtab store Only 48 installs with newtab+search override — low-visibility monetization shell.

Permissions Breakdown

• search medium Allows overriding search behavior; combined with newtab override raises monetization concern.
• host_permissions: https://api.gameograf.com/* low Scoped to developer's own API domain only.
• chrome_url_overrides.newtab medium Replaces new tab page — primary vector for traffic monetization and search hijacking.
