Top Risks

• THREAT FEED: extension ID independently confirmed malicious by TPCI chrome-mal-ids — Sunlit Spring Cat on a Flowered Fence Live Wallpaperr [adware] + malext.io malicious_extension_sentry (+2.5, capped).
• New-tab override with uninstall+install URL hijack to gameograf.com — monetization shell pattern.
• Privacy policy is Google's own policy (scope_extension=false, data_collection=true, third_party_sharing=true) — scores max 10.0.
• Two innerHTML DOM-XSS sinks with no CSP present — elevated XSS risk on new-tab page.
• No developer name listed; verified publisher but missing 'Offered by' identity field.

• no_developer_name store developer_name is empty string; 'Offered by' field missing despite verified_publisher=true.
• verified_publisher store verified_publisher=true; developer domain gameograf.com resolves and is not throwaway.
• low_installs_newtab store Only 183 installs for a NewTab override with search + uninstall/install hijack — tail attack surface.
• threat_feed_membership api Extension ID listed by TPCI chrome-mal-ids — Sunlit Spring Cat on a Flowered Fence Live Wallpaperr [adware] + malext.io malicious_extension_sentry; score 4.59 -> 7.09 (+2.5 cap 2.5).
