Top Risks

• THREAT FEED: extension ID independently confirmed malicious by TPCI chrome-mal-ids — AliExpress Deals Countdown - Flash Sale Timer [adware] [divergent] + malext.io malicious_extension_sentry (+2.5, capped).
• Privacy policy admits data collection AND third-party sharing without scoping to this extension (v3.5 D → +10.0 privacy).
• Uninstall-URL hijack routes users to saxsos.xyz on removal — classic monetization/tracking shell pattern (+3.0 webstore).
• Free-webmail developer (gmail) with no verified business identity; saxsos.xyz is the sole infra domain (+1.5 reputation).
• JS external host saxsos.xyz also serves the privacy policy and uninstall page — single throwaway-looking domain controls all telemetry surface.

• threat_feed_membership api Extension ID listed by TPCI chrome-mal-ids — AliExpress Deals Countdown - Flash Sale Timer [adware] [divergent] + malext.io malicious_extension_sentry; score 5.02 -> 7.52 (+2.5 cap 2.5).
