Top Risks

• THREAT FEED: extension ID independently confirmed malicious by TPCI chrome-mal-ids — Obanai Iguro Live Wallpaper [adware] + malext.io malicious_extension_sentry (+2.5, capped).
• NewTab override replaces every new tab; combined with install/uninstall URL hijacks signals monetization shell pattern.
• Privacy policy is Google's generic account policy — not scoped to this extension; admits data collection and 3rd-party sharing.
• Uninstall and install URL hijacks redirect to gameograf.com tracking URLs (utm parameters).
• Two innerHTML DOM-XSS sinks with no CSP present; elevated DOM-XSS risk.

Evidence

• newtab_override manifest chrome_url_overrides.newtab = newtab.html; replaces every new tab page.
• uninstall_url_hijack crx setUninstallURL to gameograf.com with utm tracking params.
• install_url_hijack crx onInstalled opens gameograf.com with utm install tracking params.
• generic_privacy_policy store Privacy URL is Google's own account policy; scope_extension=false, data_collection=true, third_party_sharing=true.
• no_csp manifest content_security_policy is null; MV3 default applies but no explicit hardening.
• dom_xss_sinks crx innerHTML assigned from variable in popup.js and calendar.js with no CSP.
• no_developer_name store developer_name is empty string; reduces accountability despite verified publisher.
• verified_publisher store verified_publisher=true; partial reputation credit but policy and name gaps remain.
• threat_feed_membership api Extension ID listed by TPCI chrome-mal-ids — Obanai Iguro Live Wallpaper [adware] + malext.io malicious_extension_sentry; score 5.32 -> 7.82 (+2.5 cap 2.5).

Permissions Breakdown

• search medium Can override search provider; medium risk for query interception.
• 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 — high reach, monetization vector.
