Top Risks

• THREAT FEED: extension ID independently confirmed malicious by TPCI chrome-mal-ids — Red Smoke Sports Car Live Wallpaper [adware] + malext.io malicious_extension_sentry (+2.5, capped).
• NewTab override with search permission creates monetization/redirect surface on every new tab.
• Uninstall and install URL hijacks redirect users to gameograf.com tracking URL.
• No CSP present (MV3 default applies) combined with innerHTML sinks creates DOM-XSS risk.
• No developer name listed despite verified publisher status reduces accountability.

• broad_js_hosts crx 12 external JS hosts contacted including chat.openai.com, mail.google.com, etc.

Permissions Breakdown

• search medium Allows reading/modifying search provider; medium risk paired with newtab override.
• host_permissions: https://api.gameograf.com/* low Scoped to own API domain; low breadth.
• chrome_url_overrides.newtab medium Replaces new-tab page; high-reach surface for monetization/redirect.
