Top Risks

• THREAT FEED: extension ID independently confirmed malicious by TPCI chrome-mal-ids — Peppa Pig Live Wallpaper [adware] + malext.io malicious_extension_sentry (+2.5, capped).
• NewTab override monetizes every new tab; search override allows provider hijack.
• Uninstall and install URL hijack to gameograf.com with UTM tracking — monetization shell pattern.
• Two innerHTML DOM-XSS sinks with no CSP — elevated XSS risk.
• No developer name listed; verified publisher provides limited accountability.

Evidence

• newtab_override manifest chrome_url_overrides.newtab = newtab.html — every new tab captured.
• 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_sinks crx innerHTML from variable in popup.js and calendar.js; no CSP to mitigate.
• no_csp manifest content_security_policy is null — MV3 default applies but no explicit hardening.
• broad_js_hosts crx 12 external JS hosts including chat.openai.com — wide network surface for a wallpaper.
• no_developer_name store developer_name is empty string; reduces accountability.
• privacy_policy_scoped api Policy fetched; scope_extension=true, data_collection=true, retention=true, third_party_sharing=true.
• threat_feed_membership api Extension ID listed by TPCI chrome-mal-ids — Peppa Pig Live Wallpaper [adware] + malext.io malicious_extension_sentry; score 2.93 -> 5.43 (+2.5 cap 2.5).

Permissions Breakdown

• search medium Allows overriding browser search provider — monetization risk for NewTab extension.
• host_permissions: https://api.gameograf.com/* low Scoped to developer's own API domain; limited blast radius.
• chrome_url_overrides.newtab medium NewTab override gives extension prime browser real estate on every new tab.
