Top Risks

• THREAT FEED: extension ID independently confirmed malicious by TPCI chrome-mal-ids — Kuromi With Friends Live Wallpaper [adware] + malext.io malicious_extension_sentry (+2.5, capped).
• NewTab override with search permission enables traffic and search monetization.
• Privacy policy is Google's generic policy — does NOT disclose what THIS extension collects.
• Uninstall and install URL hijacks redirect users to gameograf.com for campaign tracking.
• No developer name listed; no CSP on MV3 extension with innerHTML DOM-XSS sinks.

Evidence

• newtab_override manifest chrome_url_overrides.newtab = newtab.html; replaces new-tab page for all users.
• 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
• generic_privacy_policy api Privacy URL is Google's own policy (myaccount.google.com/privacypolicy); scope_extension=false, data_collection=true, third_party_sharing=true.
• dom_xss_sink crx innerHTML assigned from variable in popup.js and calendar.js with no CSP — DOM-XSS risk.
• no_developer_name store developer_name is empty string; reduces accountability.
• search_permission_newtab manifest search permission combined with newtab override typical of monetization-shell pattern.
• no_csp manifest content_security_policy is null; csp_present=false despite innerHTML sinks in JS.
• threat_feed_membership api Extension ID listed by TPCI chrome-mal-ids — Kuromi With Friends Live Wallpaper [adware] + malext.io malicious_extension_sentry; score 5.36 -> 7.86 (+2.5 cap 2.5).

Permissions Breakdown

• search medium Allows overriding search provider; medium risk for a NewTab/wallpaper extension.
• host_permission: https://api.gameograf.com/* low Scoped to dev's own API domain; expected for a live-wallpaper extension.
• chrome_url_overrides.newtab medium Replaces new-tab page — primary mechanism for traffic monetization in this category.
