Top Risks

• THREAT FEED: extension ID independently confirmed malicious by TPCI chrome-mal-ids — White Hair Anime Girl Live Wallpaper - New Tab Theme [adware] + malext.io malicious_extension_sentry (+2.5, capped).
• NewTab override replaces every new tab — prime monetization/redirect surface with only 46 installs.
• Uninstall and install URL hijack to gameograf.com — unsolicited traffic-routing on lifecycle events.
• No CSP (csp_present=false) on MV3 extension with innerHTML sinks — DOM-XSS risk elevated.
• No developer name listed despite verified publisher; low install count limits visibility into behaviour.
