Top Risks

• THREAT FEED: extension ID independently confirmed malicious by TPCI chrome-mal-ids — Skull AI Live Wallpaper New Tab [adware] + malext.io malicious_extension_sentry (+2.5, capped).
• Privacy policy is Google's own policy (not scoped to this extension) — admits data collection and 3rd-party sharing without extension-specific disclosure.
• Uninstall URL hijack and install URL hijack to gameograf.com — classic monetization shell behaviour.
• NewTab override with search permission — primary monetization vector; no search-redirect probe possible.
• Two innerHTML DOM-XSS sinks with no CSP in place, increasing XSS risk from api.gameograf.com content.

Permissions Breakdown

• chrome_url_overrides.newtab medium Replaces every new tab; primary vector for search monetization.
