Top Risks

• THREAT FEED: extension ID independently confirmed malicious by TPCI chrome-mal-ids — Anime Girl Live Wallpaper - New Tab Theme [adware] + malext.io malicious_extension_sentry (+2.5, capped).
• NewTab override replaces new tab page — high-reach monetization surface on every new tab.
• Uninstall and install URL hijack both fire to gameograf.com — lifecycle tracking.
• No CSP declared (MV3): DOM-XSS sinks in popup.js and calendar.js lack CSP protection.
• No developer name listed; verified publisher but anonymous branding reduces accountability.

Evidence

• newtab_override manifest chrome_url_overrides.newtab set to newtab.html; replaces every new tab.
• uninstall_url_hijack crx setUninstallURL targets https://gameograf.com/?utm_source=extension&utm_medium=install
• install_url_hijack crx onInstalled opens https://gameograf.com/?utm_source=extension&utm_medium=install
• no_csp manifest content_security_policy is null; csp_present=false on MV3 extension.
• dom_xss_sink crx innerHTML user-controlled in popup.js and calendar.js without CSP mitigation.
• verified_publisher store Developer verified; domain gameograf.com resolves; not throwaway.
• privacy_policy_adequate api Policy fetched; scoped, data_collection=true, retention=true, third_party_sharing=true.
• low_install_newtab store Only 134 installs; NewTab+search override with tiny audience raises tail-risk flag.
• threat_feed_membership api Extension ID listed by TPCI chrome-mal-ids — Anime Girl Live Wallpaper - New Tab Theme [adware] + malext.io malicious_extension_sentry; score 2.86 -> 5.36 (+2.5 cap 2.5).

Permissions Breakdown

• search medium Allows overriding search provider; medium risk for NewTab extension.
• host_permissions: https://api.gameograf.com/* low Scoped to developer's own API domain; acceptable for content delivery.
• chrome_url_overrides.newtab medium Replaces new tab page; primary attack surface for traffic monetization.
