Top Risks

• THREAT FEED: extension ID independently confirmed malicious by TPCI chrome-mal-ids — Cyberpunk Son Goku Live Wallpaper [adware] + malext.io malicious_extension_sentry (+2.5, capped).
• Privacy policy is Google's generic policy — not scoped to this extension; data collection and 3rd-party sharing admitted without extension-specific context.
• NewTab override replaces every new tab; combined with 'search' permission and uninstall/install URL hijacks this is a monetization shell pattern.
• Uninstall and install URL hijacks redirect to developer's site — traffic-capture pattern.
• Two innerHTML sinks without CSP present — DOM-XSS risk on the new tab page exposed to all users.

Evidence

• newtab_override manifest chrome_url_overrides.newtab = newtab.html; replaces every new tab for all 1,000 users.
• uninstall_url_hijack crx setUninstallURL → https://gameograf.com/cyberpunk-son-goku-live-wallpaper/; traffic-capture on removal.
• install_url_hijack crx onInstalled opens https://gameograf.com/cyberpunk-son-goku-live-wallpaper/; typical monetization shell.
• generic_privacy_policy store Policy URL is myaccount.google.com/privacypolicy — Google's own policy, scope_extension=false, data_collection=true, third_party_sharing=true.
• dom_xss_sink_no_csp crx innerHTML sinks in popup.js and calendar.js with csp_present=false; DOM-XSS exposure on new tab.
• no_developer_name store developer_name is empty string; reduces accountability.
• verified_publisher store verified_publisher=true for gameograf.com (resolves, not throwaway, age 2050 days); partial reputation credit.
• search_override_plus_newtab manifest 'search' permission + newtab override + 1 search engine (google.com) — monetization-adjacent pattern.
• threat_feed_membership api Extension ID listed by TPCI chrome-mal-ids — Cyberpunk Son Goku Live Wallpaper [adware] + malext.io malicious_extension_sentry; score 5.49 -> 7.99 (+2.5 cap 2.5).

Permissions Breakdown

• search medium Allows reading/modifying search provider; paired with newtab override raises monetization concern.
• host_permissions: https://api.gameograf.com/* low Scoped to developer's own API domain; limited blast radius.
• chrome_url_overrides: newtab medium Replaces every new tab page; high-reach surface for ad monetization or search hijack.
