Top Risks

• THREAT FEED: extension ID independently confirmed malicious by TPCI chrome-mal-ids — Lamborghini Egypt Live Wallpaper New Tab [adware] + malext.io malicious_extension_sentry (+2.5, capped).
• NewTab override with uninstall/install URL hijack — classic traffic-monetization shell pattern.
• Two unmitigated innerHTML DOM-XSS sinks with no CSP to contain exploitation.
• No CSP on MV3 extension amplifies DOM-sink risk; any injected content can run freely.
• No developer name listed despite verified publisher status; accountability gap.

Evidence

• newtab_override manifest chrome_url_overrides.newtab set to newtab.html — controls every new tab session.
• uninstall_url_hijack crx setUninstallURL to gameograf.com with UTM tracking — webstore +3.0 signal.
• install_url_hijack crx onInstalled opens gameograf.com with UTM tracking — webstore +2.0 signal.
• no_csp manifest content_security_policy is null on MV3 extension with innerHTML sinks.
• dom_xss_sinks crx innerHTML from variable in popup.js and calendar.js — unmitigated DOM-XSS surface.
• privacy_third_party_sharing api Privacy policy confirms data collection, retention, and third-party sharing.
• verified_publisher store Verified publisher badge present; domain resolves; not throwaway.
• no_developer_name store developer_name is empty string despite verified publisher claim.
• threat_feed_membership api Extension ID listed by TPCI chrome-mal-ids — Lamborghini Egypt Live Wallpaper New Tab [adware] + malext.io malicious_extension_sentry; score 4.29 -> 6.79 (+2.5 cap 2.5).

Permissions Breakdown

• search medium Allows querying search engine; low standalone risk but pairs with newtab override.
• chrome_url_overrides.newtab medium Replaces new-tab page; primary monetization surface for this extension type.
• host_permissions: https://api.gameograf.com/* low Scoped to developer's own API domain only; contained surface.
