Top Risks

• THREAT FEED: extension ID independently confirmed malicious by TPCI chrome-mal-ids — Pink Anime Girl Live Wallpaper [adware] + malext.io malicious_extension_sentry (+2.5, capped).
• NewTab override with uninstall/install URL hijack to gameograf.com — monetization shell pattern.
• Privacy policy is Google's own policy (not scoped to this extension) and admits data collection + 3rd-party sharing → +10 privacy score.
• No CSP declared (MV3 default applies, but csp_present==false noted); innerHTML DOM-XSS sinks in popup.js and calendar.js.
• Developer name field empty; verified publisher but policy points to unrelated Google domain.

• maintenance_stale store months_since_update=7; falls in 3-6 month band (+1.5 maintenance).
• threat_feed_membership api Extension ID listed by TPCI chrome-mal-ids — Pink Anime Girl Live Wallpaper [adware] + malext.io malicious_extension_sentry; score 5.44 -> 7.94 (+2.5 cap 2.5).
