Top Risks

• THREAT FEED: extension ID independently confirmed malicious by TPCI chrome-mal-ids — Deku And Shigaraki Live Wallpaper [adware] + malext.io malicious_extension_sentry (+2.5, capped).
• NewTab override with search permission = search monetization shell; installs/uninstall URL hijack confirmed.
• Privacy policy is Google's generic account policy — not scoped to this extension; data_collection+third_party_sharing admitted.
• Uninstall and install URL hijacks redirect to gameograf.com with UTM tracking on every lifecycle event.
• No CSP declared (MV3 default applies but csp_present==false); innerHTML sink in popup.js raises DOM-XSS risk.

Evidence

• newtab_override manifest chrome_url_overrides.newtab='newtab.html'; search permission declared — classic search-monetization NewTab pattern.
• uninstall_url_hijack crx setUninstallURL targets https://gameograf.com with UTM campaign params on every uninstall.
• install_url_hijack crx onInstalled opens https://gameograf.com with UTM install tracking.
• generic_privacy_policy store Privacy URL is myaccount.google.com/privacypolicy — Google's own policy, not scoped to this extension.
• privacy_policy_classification api scope_extension=false, data_collection=true, third_party_sharing=true — D clause triggers +10.0 privacy score.
• dom_sink_innerhtml crx popup.js assigns innerHTML from variable with no CSP; DOM-XSS risk if content is user/API controlled.
• no_developer_name store developer_name is empty string; reduces accountability.
• stale_extension store 15 months since last update; 199 installs, 0 ratings — low governance and oversight.
• threat_feed_membership api Extension ID listed by TPCI chrome-mal-ids — Deku And Shigaraki Live Wallpaper [adware] + malext.io malicious_extension_sentry; score 5.68 -> 8.18 (+2.5 cap 2.5).

Permissions Breakdown

• search medium Allows reading/overriding search provider; paired with newtab override = search monetization surface.
• host_permissions: https://api.gameograf.com/* low Scoped to developer's own API domain; low breadth.
• chrome_url_overrides.newtab medium Replaces new-tab page; primary monetization vector for this category.
