Top Risks

• NewTab override with uninstall/install URL hijack — classic traffic-monetization shell pattern.
• Privacy policy is Google's own account policy — not scoped to this extension; admits data collection & 3rd-party sharing.
• No CSP declared (MV3 default only) + innerHTML sinks in popup and calendar JS — DOM-XSS exposure.
• Developer name is empty; verified publisher status partially discounted by monetization-adjacent URL hijack pattern.
• New-tab replacement reaches every user session; combined with missing developer name raises accountability gap.

Evidence

• newtab_override manifest chrome_url_overrides.newtab present — replaces every new tab page.
• uninstall_url_hijack crx setUninstallURL → https://gameograf.com/?utm_source=gameograf&utm_content=uninstall
• install_url_hijack crx onInstalled opens https://gameograf.com/?utm_source=install&utm_content=install
• generic_privacy_policy api Policy is Google account-level 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 to mitigate.
• no_csp manifest content_security_policy is null; MV3 default applies but no explicit hardening.
• verified_publisher store Verified publisher badge present; discount capped at -1.0 due to monetization URL pattern (v3.5 invariant 0c).
• developer_name_missing store developer_name is empty string — no 'Offered by' accountability signal.

Permissions Breakdown

• search medium Allows reading and potentially manipulating search queries/providers.
• 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 — persistent high-reach surface for monetization.
