Top Risks

• THREAT FEED: extension ID independently confirmed malicious by TPCI chrome-mal-ids — Neko Anime Girl In The Rain Live Wallpaper [adware] + malext.io malicious_extension_sentry (+2.5, capped).
• Privacy policy is Google's generic account policy — not scoped to this extension, admits data collection and third-party sharing.
• NewTab override combined with search permission and uninstall/install URL hijacks signal monetization-shell pattern.
• Install and uninstall URL hijacks redirect to developer's own UTM-tracked marketing page.
• No developer name listed; verified-publisher status provides limited assurance given monetization signals.

• uninstall_url_hijack crx setUninstallURL to gameograf.com UTM tracking URL; +3.0 Webstore.
• install_url_hijack crx onInstalled opens gameograf.com UTM tracking URL; +2.0 Webstore.
• dom_sink_innerhtml_userctrl crx Two innerHTML sinks in popup.js and calendar.js; no CSP present → elevated DOM-XSS risk.
• no_developer_name store developer_name is empty; verified_publisher=true but no displayed name.
• csp_absent_mv3 manifest content_security_policy is null; MV3 has strict default but no explicit CSP set.
• verified_publisher store verified_publisher=true; discount applied but capped given monetization URL signals.
• threat_feed_membership api Extension ID listed by TPCI chrome-mal-ids — Neko Anime Girl In The Rain Live Wallpaper [adware] + malext.io malicious_extension_sentry; score 4.92 -> 7.42 (+2.5 cap 2.5).
