Top Risks

• THREAT FEED: extension ID independently confirmed malicious by TPCI chrome-mal-ids — Satoru Gojo With Red and Blue Circles Live Wallpaper [adware] + malext.io malicious_extension_sentry (+2.5, capped).
• NewTab override combined with uninstall/install URL hijack: classic monetization shell pattern.
• Uninstall and install URL hijacks redirect to gameograf.com with UTM tracking on every install/uninstall.
• No CSP declared (MV3 default applies) + innerHTML DOM-XSS sink in popup.js.
• Developer name field empty; extension name is fan-content (anime theme) with newtab override.

Evidence

• newtab_override manifest chrome_url_overrides.newtab = newtab.html — replaces every new tab for all users.
• uninstall_url_hijack manifest setUninstallURL → https://gameograf.com/?utm_source=gameograf&utm_medium=link&utm_campaign=bg&utm_content=uninstall
• install_url_hijack manifest onInstalled opens https://gameograf.com/?utm_source=install&utm_medium=link&utm_campaign=bg&utm_content=install
• dom_xss_sink crx js/popup.js: popupContainer.innerHTML = html — unescaped variable assigned to innerHTML.
• no_csp manifest content_security_policy is null; csp_present=false. MV3 default applies but no explicit hardening.
• developer_name_missing store developer_name is empty string; reduces accountability despite verified_publisher=true.
• stale_newtab store 15 months since last update; NewTab extension with monetization URLs and no dev name.
• verified_publisher store verified_publisher=true, domain resolves, no bad hosts — partially mitigates reputation risk.
• threat_feed_membership api Extension ID listed by TPCI chrome-mal-ids — Satoru Gojo With Red and Blue Circles Live Wallpaper [adware] + malext.io malicious_extension_sentry; score 4.22 -> 6.72 (+2.5 cap 2.5).

Permissions Breakdown

• search medium Allows reading/modifying search provider; medium risk for a NewTab wallpaper extension.
• host_permission: https://api.gameograf.com/* low Scoped to developer's own API domain; limited reach.
• chrome_url_overrides.newtab medium Replaces new-tab page; monetization vector common in this category.
