Top Risks

• THREAT FEED: extension ID independently confirmed malicious by TPCI chrome-mal-ids — Lamborghini Aventador Live Wallpaper New Tab [adware] + malext.io malicious_extension_sentry (+2.5, capped).
• NewTab override + search permission: classic search-monetization shell pattern.
• Uninstall and install URL hijacks redirect to developer domain with UTM tracking.
• No CSP defined (csp_present=false) on MV3 extension with innerHTML DOM sinks.
• No developer name listed; verified publisher but anonymous display identity.

Evidence

• newtab_override manifest chrome_url_overrides.newtab=newtab.html replaces new-tab page; combined with search permission = monetization pattern.
• uninstall_url_hijack crx setUninstallURL targets gameograf.com with UTM params; install URL hijack also present.
• no_csp manifest content_security_policy is null; MV3 default applies but no explicit CSP hardening with innerHTML sinks present.
• dom_sink_innerhtml crx Two innerHTML assignments from variables in popup.js and calendar.js — DOM-XSS sinks without CSP.
• verified_publisher store Verified publisher badge present; domain resolves, not throwaway, no bad hosts.
• third_party_sharing api Privacy policy: fetched, scoped, data_collection=true, retention=true, third_party_sharing=true.
• no_developer_name store developer_name is empty string; reduces accountability despite verified publisher status.
• search_engine_count_ok api Only 1 search engine seen (google.com); no multi-engine monetization aggregator pattern detected.
• threat_feed_membership api Extension ID listed by TPCI chrome-mal-ids — Lamborghini Aventador Live Wallpaper New Tab [adware] + malext.io malicious_extension_sentry; score 3.06 -> 5.56 (+2.5 cap 2.5).

Permissions Breakdown

• search medium Allows reading/modifying search provider; combined with newtab override raises monetization concern.
• chrome_url_overrides.newtab medium Replaces new-tab page; primary vector for search monetization in this extension category.
• host_permissions: https://api.gameograf.com/* low Scoped to developer's own API domain; narrow reach.
