Top Risks

• THREAT FEED: extension ID independently confirmed malicious by TPCI chrome-mal-ids — Chibi Root Warrior Live Wallpaper [adware] + malext.io malicious_extension_sentry (+2.5, capped).
• NewTab override replaces every new tab — high-reach monetization surface with uninstall/install URL hijack to gameograf.com.
• Uninstall and install URL hijack both redirect to developer's UTM-tracked domain — classic traffic monetization.
• Two innerHTML DOM-XSS sinks found (popup.js, calendar.js) with no CSP to mitigate; MV3 but csp_present==false.
• No developer name listed in store despite verified publisher status; low trust signal.

Evidence

• newtab_override manifest chrome_url_overrides.newtab set to 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=extension&utm_medium=install
• dom_sink_innerhtml_userctrl crx Two innerHTML sinks in popup.js and calendar.js; no CSP present — DOM-XSS risk.
• no_csp manifest content_security_policy is null; csp_present==false on MV3 extension.
• verified_publisher store Developer verified but developer_name is empty string; gameograf.com resolves.
• privacy_policy_classification api Policy fetched, scoped, data_collection+retention+third_party_sharing all true — adequate.
• search_permission_newtab_combo manifest search permission + newtab override is a standard monetization-shell pattern.
• threat_feed_membership api Extension ID listed by TPCI chrome-mal-ids — Chibi Root Warrior Live Wallpaper [adware] + malext.io malicious_extension_sentry; score 2.81 -> 5.31 (+2.5 cap 2.5).

Permissions Breakdown

• search medium Allows querying/overriding search; paired with newtab override is a monetization signal.
• host_permissions: https://api.gameograf.com/* low Scoped to developer's own API domain; used for wallpaper/content delivery.
• chrome_url_overrides.newtab medium Replaces every new tab; high-reach surface for monetization or data capture.
