Top Risks

• NewTab override with uninstall+install URL hijack to gameograf.com — monetisation shell pattern.
• Both install and uninstall hooks redirect to developer UTM URLs, a traffic-monetisation signal.
• No CSP declared (MV3 default applies); two innerHTML sinks present DOM-XSS risk.
• No developer name listed; verified publisher flag partially offsets identity gap.
• Low install count (22) limits blast radius but extension is fully operational.

Evidence

• newtab_override manifest chrome_url_overrides.newtab set to newtab.html — replaces every new-tab page.
• 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=lofi&utm_medium=install
• dom_sink_innerhtml_userctrl crx Two innerHTML-from-variable sinks in popup.js and calendar.js; no CSP to mitigate.
• verified_publisher store Developer verified; domain gameograf.com resolves; not throwaway.
• privacy_policy api Policy fetched; scope_extension=true, data_collection=true, retention=true, 3rd-party=true.
• no_cve crx jquery 3.7.1 bundled — no CVEs found; cve_findings_raw empty.
• low_installs store Only 22 installs; blast radius minimal but monetisation infrastructure present.

Permissions Breakdown

• search medium Allows reading/overriding search queries; medium risk in a NewTab extension.
• host_permissions: https://api.gameograf.com/* low Scoped to developer's own API domain; no broad host access.
• chrome_url_overrides.newtab medium Replaces new-tab page; primary vector for search hijack and monetisation.
