Top Risks

• THREAT FEED: extension ID independently confirmed malicious by TPCI chrome-mal-ids — Maserati Live Wallpaper New Tab [adware] + malext.io malicious_extension_sentry (+2.5, capped).
• NewTab override replaces every new tab — high-reach search monetization surface.
• Uninstall and install URL hijack both set to gameograf.com tracking URLs.
• No developer name listed; low installs (205) with rating of 3 raises credibility concern.
• dom_sink_innerhtml_userctrl in calendar.js with no CSP present — DOM-XSS risk.
