Top Risks

• THREAT FEED: extension ID independently confirmed malicious by TPCI chrome-mal-ids — Ram And Rem Re:Zero Live Wallpaper [adware] + malext.io malicious_extension_sentry (+2.5, capped).
• NewTab override with uninstall+install URL hijack to gameograf.com — monetization shell pattern.
• Two DOM-XSS innerHTML sinks with no CSP — elevated exploitability if API data is attacker-influenced.
• No developer name listed; verified publisher but missing 'Offered by' display name.
• Search permission + newtab override combo enables full search-traffic capture/redirect.

Evidence

• newtab_override manifest chrome_url_overrides.newtab set to newtab.html — replaces every new-tab page.
• uninstall_url_hijack crx setUninstallURL → https://gameograf.com/?utm_source=gameograf&utm_medium=link&utm_campaign=bg&utm_content=uninstall
• install_url_hijack crx onInstalled opens https://gameograf.com/?utm_source=install&utm_medium=link&utm_campaign=bg&utm_content=install
• dom_xss_sink crx innerHTML assigned from variable in popup.js and calendar.js; no CSP to mitigate.
• no_csp manifest content_security_policy is null; MV3 default applies but no explicit hardening.
• verified_publisher store verified_publisher=true, domain gameograf.com resolves, not throwaway.
• privacy_policy api Policy fetched, scoped to extension, documents collection/retention/third-party sharing.
• no_developer_name store developer_name is empty string; 'Offered by' not populated.
• threat_feed_membership api Extension ID listed by TPCI chrome-mal-ids — Ram And Rem Re:Zero Live Wallpaper [adware] + malext.io malicious_extension_sentry; score 4.07 -> 6.57 (+2.5 cap 2.5).

Permissions Breakdown

• search medium Allows overriding search provider; medium risk in context of NewTab override.
• host_permissions: https://api.gameograf.com/* low Scoped to developer's own API domain only.
• chrome_url_overrides.newtab medium Replaces new-tab page; primary monetization/tracking surface for this category.
