Top Risks

• THREAT FEED: extension ID independently confirmed malicious by TPCI chrome-mal-ids — Nissan Skyline Live Wallpaper New Tab [adware] + malext.io malicious_extension_sentry (+2.5, capped).
• NewTab override replaces every new tab — primary monetization/tracking surface with no privacy policy accessible.
• Uninstall and install URL hijacks both fire to gameograf.com tracking URLs, indicating monetization intent.
• Privacy policy fetch failed; policy cannot be evaluated — scored as non-fetched (+10 privacy).
• No developer name listed; reputation accountability gap.

Evidence

• newtab_override manifest chrome_url_overrides.newtab set to newtab.html — captures every new tab session.
• uninstall_url_hijack crx setUninstallURL targets https://gameograf.com/?p=6172?utm_source=extension&utm_medium=uninstall
• install_url_hijack crx onInstalled opens https://gameograf.com/?p=6172?utm_source=extension&utm_medium=install
• privacy_policy_fetch_failed api fetch_error:HTTPError on https://gameograf.com/privacy-policy/ — policy unverifiable, scored +10.
• no_developer_name store developer_name is empty string; no verified publisher badge; accountability gap.
• dom_sink_innerhtml_userctrl crx js/calendar.js assigns user-controlled HTML to innerHTML with no CSP — DOM-XSS sink.
• csp_absent manifest content_security_policy is null on MV3 extension; no mitigation for XSS findings.
• search_permission_newtab_combo manifest 'search' permission + newtab override allows passive capture of all search queries entered.
• threat_feed_membership api Extension ID listed by TPCI chrome-mal-ids — Nissan Skyline Live Wallpaper New Tab [adware] + malext.io malicious_extension_sentry; score 5.47 -> 7.97 (+2.5 cap 2.5).
