Top Risks

• THREAT FEED: extension ID independently confirmed malicious by TPCI chrome-mal-ids — Goku in Neon City Live Wallpaper [adware] + malext.io malicious_extension_sentry (+2.5, capped).
• NewTab override with uninstall+install URL hijack — classic monetization shell pattern.
• Uninstall URL hijack to gameograf.com UTM tracking confirmed.
• Install URL hijack to gameograf.com UTM tracking confirmed.
• Two DOM-XSS innerHTML sinks with no CSP; MV3 mitigates but risk remains.

Evidence

• newtab_override manifest chrome_url_overrides.newtab set to newtab.html — replaces every new tab.
• 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 constrain script execution.
• no_csp manifest content_security_policy is null; MV3 provides some default but no explicit hardening.
• verified_publisher store Verified publisher badge present; domain resolves, not throwaway.
• privacy_policy_scope api Policy fetched; scope_extension=true, data_collection=true, retention=true, third_party_sharing=true.
• low_install_newtab store Only 99 installs for a newtab wallpaper extension; minimal blast radius currently.
• threat_feed_membership api Extension ID listed by TPCI chrome-mal-ids — Goku in Neon City Live Wallpaper [adware] + malext.io malicious_extension_sentry; score 4.08 -> 6.58 (+2.5 cap 2.5).

Permissions Breakdown

• search medium Allows reading/modifying search queries; combined with newtab override raises monetization concern.
• host_permissions: https://api.gameograf.com/* low Scoped to developer's own API domain; expected for a wallpaper/newtab extension.
• chrome_url_overrides: newtab medium Replaces new-tab page; primary monetization surface for this category.
