Top Risks

• THREAT FEED: extension ID independently confirmed malicious by TPCI chrome-mal-ids — Anime Girl Daisy Eyes Live Wallpaper [adware] + malext.io malicious_extension_sentry (+2.5, capped).
• NewTab override replaces every new tab — primary monetization/search-hijack surface.
• Uninstall and install URL hijacks both present, routing users to gameograf.com tracking URLs.
• Two innerHTML DOM-XSS sinks (popup.js, calendar.js) with no CSP to mitigate.
• No developer name listed despite verified publisher status; low install count (108) limits blast radius today.

Evidence

• newtab_override manifest chrome_url_overrides.newtab = newtab.html — replaces every new tab page.
• uninstall_url_hijack crx setUninstallURL -> https://gameograf.com/?utm_source=extension&utm_medium=install
• install_url_hijack crx onInstalled opens https://gameograf.com/?utm_source=lofi&utm_medium=install
• dom_xss_sink crx dom_sink_innerhtml_userctrl in js/popup.js and js/calendar.js; no CSP present.
• no_csp manifest content_security_policy is null; MV3 default applies but no explicit CSP hardening.
• verified_publisher store Developer verified (support@gameograf.com, resolves); -3.0 reputation discount applied.
• privacy_policy_classification api Fetched, scoped, data_collection+retention+third_party_sharing all true; adequate.
• search_permission_newtab manifest 'search' permission paired with newtab override; classic search-monetization fingerprint.
• threat_feed_membership api Extension ID listed by TPCI chrome-mal-ids — Anime Girl Daisy Eyes Live Wallpaper [adware] + malext.io malicious_extension_sentry; score 2.81 -> 5.31 (+2.5 cap 2.5).

Permissions Breakdown

• search medium Allows reading/manipulating search queries; medium risk for a NewTab extension.
• host_permissions: https://api.gameograf.com/* low Scoped to dev-owned domain only; low risk on its own.
• chrome_url_overrides.newtab medium Replaces new-tab page — core monetization surface for search-hijack patterns.
