Top Risks

• THREAT FEED: extension ID independently confirmed malicious by TPCI chrome-mal-ids — Networthy [adware] [divergent] + malext.io malicious_extension_sentry (+2.5, capped).
• NewTab override replaces every new tab with arcade game; prime monetization/injection surface.
• Privacy policy is Google's generic policy — not scoped to this extension, admits data collection & 3rd-party sharing → +10.0 privacy pillar.
• 34 months without update (>24mo stale) on an active newtab extension is a takeover risk.
• Developer uses free webmail (proton.me), no business website, no verified publisher badge.
