Top Risks

• THREAT FEED: extension ID independently confirmed malicious by TPCI chrome-mal-ids — Saja Boys with KPop Demon Hunters Live Wallpaper [adware] + malext.io malicious_extension_sentry (+2.5, capped).
• Privacy policy is Google's generic policy (scope_extension=false, data_collection=true, third_party_sharing=true) — no extension-specific disclosure.
• NewTab override with install+uninstall URL hijacks to gameograf.com — classic monetization shell pattern.
• Uninstall URL hijack confirmed: redirects to gameograf.com with UTM tracking on every uninstall.
• innerHTML sinks without CSP in popup.js and calendar.js expose DOM-XSS surface.

Evidence

• newtab_override manifest chrome_url_overrides.newtab = newtab.html — replaces every new tab; monetization surface.
• 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 account policy; scope_extension=false, data_collection=true, third_party_sharing=true.
• dom_xss_sink crx innerHTML sinks in popup.js and calendar.js; csp_present=false amplifies risk.
• no_developer_name store developer_name is empty string; no verified publisher or featured badge.
• newtab_monetization_shape store Wallpaper/theme extension overrides new tab with search permission — traffic monetization pattern.
• domain_established api gameograf.com age ~2050 days, 265 certs; domain resolves, not throwaway.
• threat_feed_membership api Extension ID listed by TPCI chrome-mal-ids — Saja Boys with KPop Demon Hunters Live Wallpaper [adware] + malext.io malicious_extension_sentry; score 5.31 -> 7.81 (+2.5 cap 2.5).

Permissions Breakdown

• search medium Allows reading/manipulating search queries; combined with newtab override increases monetization risk.
• host_permissions: https://api.gameograf.com/* low Scoped to developer's own API domain; limited blast radius.
• chrome_url_overrides.newtab medium Replaces new tab page — primary monetization surface; captures all new-tab navigation intent.
