Top Risks

• THREAT FEED: extension ID independently confirmed malicious by TPCI chrome-mal-ids — Billie Eilish Wallpapers New Tab Experience [adware] + malext.io malicious_extension_sentry (+2.5, capped).
• Privacy policy is Google's generic account policy — not scoped to this extension at all; admits data collection and 3rd-party sharing.
• Uninstall and install URL hijacks route users to gameograf.com for traffic/monetization tracking.
• NewTab override with 10 external JS hosts including mlionltd.github.io (unrecognised 3rd-party CDN).
• Extension is 19 months stale with no CSP and a newtab override — elevated supply-chain risk.

• newtab_override manifest chrome_url_overrides.newtab set to index.html; every new tab controlled by extension.
• external_js_hosts crx 10 external JS hosts including mlionltd.github.io (unverified GitHub Pages CDN) and major platforms.
• stale_extension store 19 months since last update; no CSP; newtab override — elevated future-compromise risk.
• no_csp manifest content_security_policy is null; MV3 has strict default but external host list amplifies risk.
• verified_publisher_cap_triggered store months_since_update=19 >18 → v3.5 invariant 0c caps verified-publisher discount at -1.0.
• threat_feed_membership api Extension ID listed by TPCI chrome-mal-ids — Billie Eilish Wallpapers New Tab Experience [adware] + malext.io malicious_extension_sentry; score 5.61 -> 8.11 (+2.5 cap 2.5).
