Top Risks

• THREAT FEED: extension ID independently confirmed malicious by TPCI chrome-mal-ids — Saber Live Wallpaper [adware] + malext.io malicious_extension_sentry (+2.5, capped).
• NewTab override installs on every browser tab open — high reach monetization/search-injection surface.
• Uninstall and install URL hijacks redirect to gameograf.com with UTM tracking on every install/remove.
• Privacy policy URL (haberikra.com) is unreachable — no enforceable data handling disclosure.
• No CSP declared (MV3) combined with innerHTML DOM-XSS sink in popup.js.

Evidence

• newtab_override manifest chrome_url_overrides.newtab set to newtab.html — replaces every new tab for all users.
• uninstall_url_hijack crx setUninstallURL -> 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_unreachable api Fetch error (HTTPError) for https://haberikra.com/privacy-policy/ — policy not evaluable.
• dom_xss_sink crx js/popup.js: innerHTML assigned from variable without sanitization; no CSP to mitigate.
• no_csp manifest content_security_policy is null; MV3 default applies but no explicit CSP hardening.
• stale_newtab_monetization store 15 months since update, newtab override, install/uninstall hijacks — matches monetization shell pattern.
• no_developer_name store developer_name is empty string; identity accountability reduced.
• threat_feed_membership api Extension ID listed by TPCI chrome-mal-ids — Saber Live Wallpaper [adware] + malext.io malicious_extension_sentry; score 4.43 -> 6.93 (+2.5 cap 2.5).

Permissions Breakdown

• search medium Allows overriding or querying search provider; medium risk on its own.
• host_permissions: https://api.gameograf.com/* low Scoped to developer's own API domain; limited blast radius.
• chrome_url_overrides.newtab medium Replaces every new tab; high reach, potential for monetization/search injection.
