Top Risks

• Newtab override with uninstall/install URL hijack — classic traffic-monetization shell pattern.
• No CSP declared (MV3 null CSP) with innerHTML DOM-XSS sink in popup.js.
• Developer name absent; no 'Offered by' display name increases accountability gap.
• 15 months since last update — moderate staleness for an active newtab extension.
• Verified publisher but no sibling extensions and no developer name raises thin-identity concern.

Evidence

• newtab_override manifest chrome_url_overrides.newtab set to newtab.html — replaces new tab page.
• uninstall_url_hijack crx setUninstallURL targets https://gameograf.com/?utm_source=gameograf&utm_campaign=bg — 3rd-party UTM redirect.
• install_url_hijack crx onInstalled opens https://gameograf.com/?utm_source=install&utm_campaign=bg — traffic monetization on install.
• dom_sink_innerhtml_userctrl crx js/popup.js: innerHTML assigned from variable without sanitization; no CSP to mitigate.
• no_csp manifest content_security_policy is null; MV3 default applies but no explicit hardening declared.
• no_developer_name store developer_name is empty string; no 'Offered by' identity visible to users.
• verified_publisher store Extension carries verified publisher badge from Google — partial accountability.
• privacy_policy api Policy fetched; scope_extension=true, data_collection=true, retention=true, third_party_sharing=true — adequate.

Permissions Breakdown

• search medium Can read and manipulate search queries; paired with newtab override raises risk.
• chrome_url_overrides.newtab medium Replaces browser new tab page — primary monetization surface for this category.
• host_permissions: https://api.gameograf.com/* low Scoped to developer-controlled API domain only.
