Top Risks

• THREAT FEED: extension ID independently confirmed malicious by TPCI chrome-mal-ids — Woman Running Park Live Wallpaper [adware] + malext.io malicious_extension_sentry (+2.5, capped).
• NewTab override replaces every new-tab page with developer-controlled content — high reach.
• Uninstall and install URL hijack redirect to gameograf.com — traffic monetization pattern.
• No CSP on MV3 extension with DOM-XSS innerHTML sinks in popup.js and calendar.js.
• Developer name field empty; verified publisher but no display name reduces accountability.

Evidence

• newtab_override manifest chrome_url_overrides.newtab = newtab.html — replaces every new-tab for all 13 users.
• uninstall_url_hijack crx setUninstallURL → 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_csp manifest content_security_policy is null; MV3 default CSP applies but no explicit hardening.
• dom_xss_sinks crx innerHTML sinks in js/popup.js and js/calendar.js — DOM-XSS risk without CSP.
• broad_js_external_hosts crx 12 external JS hosts including chat.openai.com, Google suite — broad beyond wallpaper purpose.
• developer_name_empty store developer_name field is empty string despite verified_publisher == true.
• privacy_policy_adequate api Policy fetched; scope_extension, data_collection, retention, third_party_sharing all true.
• threat_feed_membership api Extension ID listed by TPCI chrome-mal-ids — Woman Running Park Live Wallpaper [adware] + malext.io malicious_extension_sentry; score 4.42 -> 6.92 (+2.5 cap 2.5).

Permissions Breakdown

• search medium Allows override of search provider; medium risk for a NewTab extension.
• host_permissions: https://api.gameograf.com/* low Scoped to developer's own API domain; expected for wallpaper/newtab content delivery.
• chrome_url_overrides: newtab medium Replaces new-tab page — high visibility surface, monetization vector.
