Top Risks

• THREAT FEED: extension ID independently confirmed malicious by TPCI chrome-mal-ids — Elsa Frozen Live Wallpaper New Tab [adware] + malext.io malicious_extension_sentry (+2.5, capped).
• NewTab override replaces every new-tab page; uninstall+install URL hijack signals traffic monetization intent.
• Uninstall URL hijack and install URL hijack both active — classic low-effort traffic monetization shell pattern.
• No CSP defined (MV3 with null CSP); innerHTML DOM-XSS sinks in popup.js and calendar.js increase injection risk.
• Developer name empty; verified publisher but no 'Offered by' display name reduces accountability.

Evidence

• uninstall_url_hijack crx setUninstallURL points to gameograf.com with UTM tracking — monetization pattern.
• install_url_hijack crx onInstalled opens gameograf.com with UTM install tracking — install hijack confirmed.
• newtab_override manifest chrome_url_overrides.newtab = newtab.html; replaces all new-tab pages.
• dom_sink_innerhtml_userctrl crx innerHTML assigned from variable in popup.js and calendar.js — DOM-XSS sinks with no CSP.
• csp_absent manifest content_security_policy is null; MV3 default CSP applies but no explicit hardening.
• developer_name_missing store developer_name is empty string; reduces accountability despite verified_publisher=true.
• verified_publisher store verified_publisher=true; domain resolves, not throwaway — partial trust signal.
• privacy_policy_adequate api Policy fetched; scope_extension, data_collection, retention, third_party_sharing all true — adequate.
• threat_feed_membership api Extension ID listed by TPCI chrome-mal-ids — Elsa Frozen 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; expected for NewTab but enables query interception.
• host_permissions: https://api.gameograf.com/* low Scoped to developer's own API domain; narrow host access.
• chrome_url_overrides.newtab medium Replaces every new-tab page; high user-interaction surface, monetization vector.
