Top Risks

• THREAT FEED: extension ID independently confirmed malicious by TPCI chrome-mal-ids — Anime Girl Live Wallpaper - New Tab Theme [adware] + malext.io malicious_extension_sentry (+2.5, capped).
• NewTab override with uninstall/install URL hijack — classic traffic-monetization shell pattern.
• Uninstall and install URL both redirected to gameograf.com with UTM tracking.
• No CSP declared (MV3 so no +2 penalty but innerHTML sinks are unmitigated).
• Developer name missing from listing — reduced accountability.

• dom_xss_sink crx innerHTML assigned from variable in popup.js and calendar.js — DOM-XSS risk.
• developer_name_missing store developer_name is empty string; reduced publisher accountability.
