Top Risks

• THREAT FEED: extension ID independently confirmed malicious by TPCI chrome-mal-ids — Futuristic Space Station Live Wallpaper [adware] + malext.io malicious_extension_sentry (+2.5, capped).
• NewTab override replaces every new tab; high-reach intercept for search/ad monetization.
• Uninstall and install URL hijacks redirect to gameograf.com tracking URLs.
• No CSP declared (MV3 default mitigates but doesn't eliminate DOM-XSS risk from innerHTML sinks).
• No developer name listed despite verified publisher status; reduces accountability signal.

Evidence

• newtab_override manifest chrome_url_overrides.newtab = newtab.html; replaces every new-tab page.
• 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; csp_present == false.
• dom_xss_sinks crx innerHTML assigned from variables in popup.js and calendar.js; DOM-XSS risk.
• verified_publisher store Publisher verified; caps reputation discount but newtab override triggers capability gate.
• privacy_policy api Policy fetched; scope_extension=true, data_collection=true, retention=true, third_party_sharing=true.
• no_developer_name store developer_name is empty string; reduces accountability despite verified publisher.
• threat_feed_membership api Extension ID listed by TPCI chrome-mal-ids — Futuristic Space Station Live Wallpaper [adware] + malext.io malicious_extension_sentry; score 2.88 -> 5.38 (+2.5 cap 2.5).

Permissions Breakdown

• search medium Allows reading/modifying search provider; medium risk on its own.
• host_permissions: https://api.gameograf.com/* low Scoped to developer's own API domain; low blast radius.
• chrome_url_overrides.newtab medium Replaces new-tab page; high-traffic intercept point for search monetization.
