Top Risks

• THREAT FEED: extension ID independently confirmed malicious by TPCI chrome-mal-ids — Tung Tung Tung Sahur Live Wallpaper [adware] + malext.io malicious_extension_sentry (+2.5, capped).
• NewTab override hijacks every new tab; uninstall+install URL both redirect to owhit.com (monetization shell pattern).
• Privacy policy is Google's own account policy — not scoped to this extension; admits data collection and 3rd-party sharing.
• Free-webmail dev (dostkayalar@gmail.com), no verified publisher, no business website — identity unverifiable.
• 5 sibling extensions share the same uninstall-URL domain (owhit.com), indicating an organised wallpaper-shell operator.
