Top Risks

• THREAT FEED: extension ID independently confirmed malicious by TPCI chrome-mal-ids — Clone Trooper Star Wars Live Wallpaper [adware] + malext.io malicious_extension_sentry (+2.5, capped).
• NewTab override with uninstall+install URL hijack to gameograf.com — monetization shell pattern.
• No developer name listed; reduces accountability for a newtab override extension.
• No CSP declared (MV3 default applies but no explicit policy); innerHTML sinks in popup.js and calendar.js.
• search permission combined with newtab override enables search-query capture.

Evidence

• newtab_override manifest chrome_url_overrides.newtab set to newtab.html — replaces new tab for all users.
• uninstall_url_hijack crx setUninstallURL targets https://gameograf.com/?utm_source=extension&utm_medium=install
• install_url_hijack crx onInstalled opens https://gameograf.com/?utm_source=extension&utm_medium=install
• no_developer_name store developer_name field is empty string; reduces accountability.
• dom_sink_innerhtml crx innerHTML sinks found in js/popup.js and js/calendar.js; csp_present=false amplifies risk.
• verified_publisher store verified_publisher=true on gameograf.com; domain resolves, not throwaway.
• privacy_policy api Policy fetched, scoped to extension, documents data collection, retention, and 3rd-party sharing.
• search_permission manifest search permission declared; combined with newtab override enables search monetization.
• threat_feed_membership api Extension ID listed by TPCI chrome-mal-ids — Clone Trooper Star Wars Live Wallpaper [adware] + malext.io malicious_extension_sentry; score 3.41 -> 5.91 (+2.5 cap 2.5).

Permissions Breakdown

• search medium Access to search queries; medium risk for a NewTab/wallpaper extension.
• host_permissions: https://api.gameograf.com/* low Scoped to developer's own API domain; matches stated functionality.
• chrome_url_overrides.newtab medium Replaces new tab page; primary vector for search monetization in this category.
