Top Risks

• NewTab override combined with uninstall/install URL hijack signals ad-monetization shell pattern.
• No developer name listed; verified publisher discount partially mitigated by 15-month staleness.
• innerHTML DOM-XSS sink in popup.js with no CSP present (MV3 default applies but no explicit policy).
• Uninstall URL hijack to gameograf.com UTM link — classic traffic-monetization signal.
• Install URL hijack to gameograf.com UTM link — confirms monetization-oriented lifecycle hooks.

Evidence

• newtab_override manifest chrome_url_overrides.newtab set to newtab.html — replaces every new tab for all users.
• uninstall_url_hijack crx setUninstallURL targets https://gameograf.com/?utm_source=gameograf&utm_medium=link&utm_campaign=bg&utm_content=uninstall
• install_url_hijack crx onInstalled opens https://gameograf.com/?utm_source=install&utm_medium=link&utm_campaign=bg&utm_content=install
• dom_xss_sink crx innerHTML assigned from variable in js/popup.js; no CSP to mitigate DOM-XSS.
• verified_publisher store Verified publisher badge present; discount capped at -1.0 due to months_since_update=15 (>12mo stale threshold).
• maintenance_stale store Last updated June 2025; 15 months since update falls in 12-24mo band (+6.0 maintenance score).
• no_developer_name store developer_name is empty string; reduces accountability.
• privacy_policy_adequate api Policy fetched; scope_extension, data_collection, retention, third_party_sharing all true — fully scoped.

Permissions Breakdown

• search medium Allows querying browser search settings; paired with newtab override raises monetization risk.
• 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 ad-tech monetization in this category.
