Top Risks

• THREAT FEED: extension ID independently confirmed malicious by TPCI chrome-mal-ids — Paranormal Scary Faces Live Wallpaper [adware] + malext.io malicious_extension_sentry (+2.5, capped).
• NewTab override with uninstall+install URL hijack to gameograf.com — classic monetization shell pattern.
• Uninstall and install URL hijacks both confirmed, each scoring +2.0+2.0 in webstore signals.
• search permission combined with newtab override creates search-provider monetization surface.
• No developer name listed; low install count (35) with high-impact newtab permission is anomalous.

Evidence

• newtab_override manifest chrome_url_overrides.newtab = newtab.html — replaces new-tab page.
• uninstall_url_hijack crx setUninstallURL to 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 assignments in js/popup.js and js/calendar.js without CSP guard.
• search_permission_newtab manifest search permission + newtab override = search-monetization capability.
• no_developer_name store developer_name is empty string; reduces accountability.
• verified_publisher store verified_publisher=true; partial reputation credit applied.
• threat_feed_membership api Extension ID listed by TPCI chrome-mal-ids — Paranormal Scary Faces Live Wallpaper [adware] + malext.io malicious_extension_sentry; score 4.51 -> 7.01 (+2.5 cap 2.5).

Permissions Breakdown

• search medium Allows querying the search provider; combined with newtab override amplifies search monetization risk.
• host_permissions: https://api.gameograf.com/* low Scoped to developer's own API domain; limited blast radius.
• chrome_url_overrides.newtab high Replaces new-tab page — prime monetization/search-redirect surface per rubric.
