Top Risks

• THREAT FEED: extension ID independently confirmed malicious by TPCI chrome-mal-ids — Gojo vs Sukuna Jujutsu Kaisen Live Wallpaper [adware] + malext.io malicious_extension_sentry (+2.5, capped).
• NewTab override replaces every new tab — persistent high-reach monetization/redirect surface.
• Uninstall URL hijack to developer domain with UTM tracking on every uninstall.
• Install URL hijack opens developer page on every install.
• No CSP declared (MV3 default applies) combined with innerHTML sinks — DOM-XSS risk.

Evidence

• newtab_override manifest chrome_url_overrides.newtab = newtab.html — replaces new-tab on every open.
• uninstall_url_hijack crx setUninstallURL to https://gameograf.com/?utm_source=gameograf&utm_medium=link&utm_campaign=bg
• install_url_hijack crx onInstalled opens https://gameograf.com/?utm_source=install&utm_medium=link&utm_campaign=bg
• dom_xss_sinks crx innerHTML from variable in js/popup.js and js/calendar.js — DOM-XSS sinks without CSP guard.
• no_csp manifest content_security_policy is null; csp_present=false. MV3 default applies but no explicit restriction.
• verified_publisher store Developer verified_publisher=true on gameograf.com domain which resolves.
• no_developer_name store developer_name is empty string; only email provided.
• privacy_policy_adequate api Policy fetched; scope_extension=true, data_collection=true, retention=true, third_party_sharing=true.
• threat_feed_membership api Extension ID listed by TPCI chrome-mal-ids — Gojo vs Sukuna Jujutsu Kaisen Live Wallpaper [adware] + malext.io malicious_extension_sentry; score 4.45 -> 6.95 (+2.5 cap 2.5).

Permissions Breakdown

• search medium Allows reading/overriding search provider; moderate risk for a NewTab extension.
• host_permissions: https://api.gameograf.com/* low Scoped to developer's own API domain; limited surface area.
• chrome_url_overrides.newtab medium Replaces new-tab page — primary monetization vector for this category.
