Top Risks

• NewTab override on every new tab; search permission enables query interception for monetization.
• Uninstall and install URL hijacks route users to gameograf.com tracking URLs.
• No CSP (csp_present=false) with innerHTML DOM-XSS sink in calendar.js increases XSS risk.
• No developer name listed; anime-theme shell pattern with newtab override is common in adware clusters.
• Privacy policy admits third-party sharing; extension contacts 12 JS external hosts including Google services.

Evidence

• newtab_override manifest chrome_url_overrides.newtab set to newtab.html — replaces every new tab page.
• uninstall_url_hijack crx setUninstallURL targets gameograf.com with UTM tracking params.
• install_url_hijack crx onInstalled opens gameograf.com with UTM tracking params.
• no_csp manifest content_security_policy is null; MV3 default applies but no explicit CSP hardening.
• dom_xss_sink crx innerHTML assigned from variable in js/calendar.js without sanitization.
• privacy_policy_third_party api Policy fetched; scope_extension=true, data_collection=true, third_party_sharing=true.
• verified_publisher store gameograf.com verified publisher; domain resolves, not throwaway.
• search_engine_count_1 api Only google.com seen as search engine; no multi-engine aggregator pattern.

Permissions Breakdown

• search medium Can read/override search queries; core risk for NewTab monetization.
• alarms low Schedules background tasks; low standalone risk.
• storage low Local data persistence; low risk.
• chrome_url_overrides.newtab medium Replaces every new tab; high reach, monetization surface.
• host_permissions: https://api.gameograf.com/* low Scoped to own API domain only.
