Top Risks

• THREAT FEED: extension ID independently confirmed malicious by TPCI chrome-mal-ids — Anime Girl Night Coffee Break Live Wallpaper [adware] + malext.io malicious_extension_sentry (+2.5, capped).
• Privacy policy is Google's own policy — not scoped to this extension; admits data collection and third-party sharing (Privacy +10).
• Uninstall and install URL hijacks redirect to gameograf.com UTM tracking pages — classic monetization shell signal.
• NewTab override + search permission = search monetization surface; new-tab override with monetization shape.
• Maintenance gap of 13 months with verified publisher status — stale but publisher identity confirmed.

Evidence

• dom_sink_innerhtml crx dom_sink_innerhtml_userctrl in popup.js and calendar.js. No CSP → +2.0 Code Quality (FIX B).
• verified_publisher store Verified publisher badge present; discount capped at -1.0 due to months_since_update=13 (>12, not >18) — cap not triggered by stale rule (needs >18).
• developer_name_missing store developer_name is empty string; reputation starts at 5.0 with +1.0 for no 'Offered by' name.
• maintenance_stale store months_since_update=13 falls in 12-24 month band → +6.0 Maintenance.
• threat_feed_membership api Extension ID listed by TPCI chrome-mal-ids — Anime Girl Night Coffee Break Live Wallpaper [adware] + malext.io malicious_extension_sentry; score 5.34 -> 7.84 (+2.5 cap 2.5).

Permissions Breakdown

• search medium Allows manipulating search provider; paired with newtab override this enables search monetization.
• host_permissions: https://api.gameograf.com/* low Scoped to developer's own API domain; limited blast radius.
• chrome_url_overrides: newtab medium Replaces new-tab page; primary monetization vector for this category.
