Top Risks

• NewTab override + uninstall/install URL hijack to gameograf.com — traffic-monetization shell pattern.
• No CSP on MV3 extension with innerHTML DOM sinks in popup.js and calendar.js (DOM-XSS risk).
• Developer name blank; verified publisher but no human attribution raises accountability gap.
• Uninstall URL hijack redirects to gameograf.com with UTM params — classic monetization fingerprint.
• Install URL hijack opens gameograf.com on install — onInstalled 3rd-party redirect.

Evidence

• newtab_override manifest chrome_url_overrides.newtab set to newtab.html — full new-tab replacement.
• uninstall_url_hijack crx setUninstallURL → 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_csp manifest content_security_policy is null; MV3 default CSP applies but no explicit hardening.
• dom_xss_sink crx innerHTML assigned from variable in popup.js and calendar.js — DOM-XSS sinks with no CSP.
• developer_name_missing store developer_name is empty string; verified publisher but no displayed human/org name.
• privacy_policy_scoped api Policy fetched; scope_extension=true, data_collection=true, retention=true, third_party_sharing=true.
• low_install_newtab store Only 209 installs for a NewTab theme with monetization URL hijacks — tail risk surface.

Permissions Breakdown

• search medium Allows querying search provider; expected for NewTab but enables search-monetization.
• host_permissions: https://api.gameograf.com/* low Scoped to developer's own API domain; narrow and expected for wallpaper content fetch.
• chrome_url_overrides.newtab medium Replaces new tab page — core NewTab monetization surface; scored per rule (a).
