Top Risks

• THREAT FEED: extension ID independently confirmed malicious by TPCI chrome-mal-ids — Satoru Gojo Night Time Live Wallpaper [adware] + malext.io malicious_extension_sentry (+2.5, capped).
• NewTab override with uninstall+install URL hijacking to gameograf.com — monetization shell pattern.
• No developer name listed; low-install (198) extension with search permission and newtab override.
• DOM-XSS sink (innerHTML from variable) in popup.js with no CSP present.
• Stale 15 months; newtab override remains active on all user browsers with no updates.

Evidence

• uninstall_url_hijack crx setUninstallURL → https://gameograf.com/?utm_source=gameograf&utm_medium=uninstall; 3rd-party redirect.
• install_url_hijack crx onInstalled opens https://gameograf.com/?utm_source=install; monetization install funnel.
• newtab_override manifest chrome_url_overrides.newtab = newtab.html; intercepts every new tab for 198 users.
• no_csp manifest content_security_policy is null; MV3 default applies but DOM-XSS sink unmitigated.
• dom_sink_innerhtml crx popup.js: innerHTML assigned from variable — DOM-XSS risk without CSP mitigation.
• no_developer_name store developer_name is empty string; accountability gap despite verified_publisher=true.
• stale_extension store 15 months since last update; newtab override active long-term with no patch cadence.
• verified_publisher_capability_gate api Verified publisher discount capped at -1.0: newtab+search are HIGH-impact capabilities per v2 cap rule.
• threat_feed_membership api Extension ID listed by TPCI chrome-mal-ids — Satoru Gojo Night Time Live Wallpaper [adware] + malext.io malicious_extension_sentry; score 4.39 -> 6.89 (+2.5 cap 2.5).

Permissions Breakdown

• search medium Allows read access to search queries; elevated in NewTab context with search override.
• 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; prime monetization surface, intercepts every new tab.
