Top Risks

• THREAT FEED: extension ID independently confirmed malicious by TPCI chrome-mal-ids — Fairy Wings Live Wallpaper Theme [adware] + malext.io malicious_extension_sentry (+2.5, capped).
• NewTab override on every new tab combined with uninstall/install URL hijack to gameograf.com — persistent monetization surface.
• Uninstall and install URL hijack both redirect to gameograf.com with UTM tracking on every install/uninstall.
• No CSP present (MV3 default applies but csp_present=false); innerHTML sinks in popup.js and calendar.js increase DOM-XSS risk.
• No developer name listed in store; only email identity; reduces accountability signal.

Evidence

• newtab_override manifest chrome_url_overrides.newtab set to newtab.html — hijacks 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
• dom_xss_sinks crx innerHTML assignments from variables in js/popup.js and js/calendar.js; no CSP to mitigate.
• no_developer_name store developer_name is empty string; only email support@gameograf.com provided.
• verified_publisher store Extension has verified_publisher=true; partial reputation credit applied.
• privacy_policy_adequate api Policy fetched; scope_extension=true, data_collection=true, retention=true, third_party_sharing=true.
• broad_js_hosts crx 12 external JS hosts including api.gameograf.com and multiple Google service domains.
• threat_feed_membership api Extension ID listed by TPCI chrome-mal-ids — Fairy Wings Live Wallpaper Theme [adware] + malext.io malicious_extension_sentry; score 2.88 -> 5.38 (+2.5 cap 2.5).

Permissions Breakdown

• search medium Allows reading/modifying search provider settings; medium risk for a NewTab extension.
• host_permissions: https://api.gameograf.com/* low Scoped to developer's own API domain; low risk on its own.
• chrome_url_overrides.newtab medium NewTab override gives persistent presence on every new tab; monetization risk.
