Top Risks

• Uninstall and install URL hijack: both redirect to gameograf.com with tracking params on every install/uninstall.
• NewTab override gives persistent reach on every browser new-tab; monetization shape is present.
• No developer name listed; low install count (914) with perfect 5-star rating is unverifiable.
• months_since_update=15 triggers stale-maintenance penalty; extension last touched mid-2023.
• innerHTML DOM-XSS sink in popup.js without CSP guard, though no exfil path confirmed.

Evidence

• uninstall_url_hijack manifest setUninstallURL → https://gameograf.com/?utm_source=gameograf&utm_medium=link&utm_campaign=bg&utm_content=uninstall
• install_url_hijack manifest onInstalled opens https://gameograf.com/?utm_source=install&utm_medium=link&utm_campaign=bg&utm_content=install
• newtab_override manifest chrome_url_overrides.newtab = newtab.html; persistent reach on every new tab.
• no_developer_name store developer_name is empty string; reduces accountability.
• dom_sink_innerhtml crx js/popup.js: innerHTML assigned from variable with no CSP — DOM-XSS risk.
• csp_absent manifest content_security_policy is null; MV3 default applies but no explicit hardening.
• stale_maintenance store months_since_update=15; falls in 12-24mo band (+6.0 maintenance).
• verified_publisher store Verified publisher badge present; discount applied but capped due to staleness >12mo.

Permissions Breakdown

• search medium Allows reading and manipulating search queries; medium risk in NewTab context.
• host_permission: https://api.gameograf.com/* low Scoped to developer's own API domain; limited blast radius.
• chrome_url_overrides.newtab medium Replaces new-tab page; monetization vector and persistent reach on every new tab.
