Top Risks

• THREAT FEED: extension ID independently confirmed malicious by TPCI chrome-mal-ids — One Piece Poster Live Wallpaper [adware] + malext.io malicious_extension_sentry (+2.5, capped).
• Uninstall URL hijack to owhit.com and install URL hijack — classic low-effort traffic-monetization shell pattern.
• Privacy policy is Google's generic account policy — not scoped to this extension, admits data collection and 3rd-party sharing.
• Free-webmail developer (gokturksener476@gmail.com) with no verified business identity; developer name 'Newtab' is generic.
• NewTab override with search permission enables full control of new-tab search traffic for ad monetization.

• js_external_hosts_broad crx 8 external JS hosts including owhit.com, instagram.com, netflix.com, x.com, youtube.com — broad reach beyond stated function.
• no_csp manifest content_security_policy is null; no CSP protection despite external host references.
• new_tab_monetization_shape store NewTab override + install/uninstall URL hijack + free-webmail dev = low-effort traffic-monetization cluster.
• threat_feed_membership api Extension ID listed by TPCI chrome-mal-ids — One Piece Poster Live Wallpaper [adware] + malext.io malicious_extension_sentry; score 5.46 -> 7.96 (+2.5 cap 2.5).
