Top Risks

• THREAT FEED: extension ID independently confirmed malicious by TPCI chrome-mal-ids — jecdgiaibpgdhnbmmafjlnleoihbigbd [adware] + malext.io malicious_extension_sentry (+2.5, capped).
• Uninstall URL hijack to yowgames.com — classic game-portal monetization shell pattern.
• Install URL hijack opens yowgames.com on install — forced traffic to third-party site.
• Privacy policy is Google's own policy, not scoped to this extension; admits data collection and third-party sharing.
• New-tab override combined with 'search' permission and free-webmail dev — high monetization risk.
