Top Risks

• THREAT FEED: extension ID independently confirmed malicious by TPCI chrome-mal-ids — Radiant Christ | Jesus Live Wallpaper [adware] + malext.io malicious_extension_sentry (+2.5, capped).
• NewTab override hijacks every new tab for a wallpaper/search monetization shell.
• Privacy policy is Google's own policy — not scoped to this extension; admits data collection & third-party sharing.
• Uninstall and install URL hijacks redirect to gameograf.com marketing pages.
• No CSP declared (MV3 exemption applies but no explicit policy) with innerHTML DOM-XSS sinks present.

Evidence

• newtab_override manifest chrome_url_overrides.newtab set to newtab.html — replaces every new tab for this theme/wallpaper extension.
• uninstall_url_hijack crx setUninstallURL targets https://gameograf.com/?utm_campaign=bg&utm_content=uninstall — 3rd-party redirect.
• install_url_hijack crx onInstalled opens https://gameograf.com/stranger-things-5-live-wallpaper/ — unrelated product, monetization pattern.
• generic_privacy_policy store Privacy policy URL is Google's own account policy; scope_extension=false, data_collection=true, third_party_sharing=true.
• dom_xss_sink crx Two innerHTML assignments from variables in popup.js and calendar.js; csp_present=false amplifies risk.
• no_developer_name store developer_name is empty string despite verified_publisher=true.
• search_override_plus_newtab manifest 'search' permission combined with newtab override signals search-monetization shell pattern.
• maintenance_stale store months_since_update=7 (3-6mo boundary exceeded); scores +3.5 maintenance penalty.
• threat_feed_membership api Extension ID listed by TPCI chrome-mal-ids — Radiant Christ | Jesus Live Wallpaper [adware] + malext.io malicious_extension_sentry; score 5.44 -> 7.94 (+2.5 cap 2.5).

Permissions Breakdown

• search medium Allows overriding search provider; paired with newtab override amplifies search-monetization risk.
• 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 — prime real estate for ad monetization and data collection.
