Top Risks

• NewTab override + search permission: classic search-monetization shell pattern
• Privacy policy is Google's own policy (scope_extension=false, data_collection=true, third_party_sharing=true) — completely inadequate
• Uninstall URL hijack routes to gameograf.com UTM campaign — user tracking on removal
• Install URL hijack opens gameograf.com on install — affiliate/monetization trigger
• No CSP declared (MV3 so no +2 Network penalty, but innerHTML sink without CSP raises DOM-XSS risk)

Evidence

• newtab_override manifest chrome_url_overrides.newtab = newtab.html; replaces every new tab with extension page.
• uninstall_url_hijack crx setUninstallURL to 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
• privacy_policy_generic store Privacy policy is Google's account policy (scope_extension=false, admits data_collection+third_party_sharing).
• dom_xss_sink crx innerHTML assigned from variable in js/popup.js with no CSP; DOM-XSS risk.
• no_developer_name store developer_name field is empty; accountability gap.
• maintenance_stale store 15 months since last update; in 6-24mo band (+6.0 maintenance).
• verified_publisher store Verified publisher badge present; partially mitigates reputation, but monetization pattern limits discount (0c cap applies).

Permissions Breakdown

• search medium Allows manipulation of the browser's search provider — combined with newtab override is a monetization vector.
• host_permissions: 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 and search-hijack surface.
