Top Risks

• THREAT FEED: extension ID independently confirmed malicious by TPCI chrome-mal-ids — Frieren blooming [adware] + malext.io malicious_extension_sentry (+2.5, capped).
• NewTab override enables persistent monetization/ad injection on every browser tab.
• Uninstall and install URL hijack both redirect to gameograf.com tracking URL — classic traffic monetization pattern.
• No CSP declared (MV3) combined with innerHTML sinks in popup.js and calendar.js creates DOM-XSS exposure.
• Search permission paired with NewTab override suggests search-provider monetization intent.

Evidence

• newtab_override manifest chrome_url_overrides.newtab set to newtab.html — persistent control of every new tab.
• uninstall_url_hijack crx setUninstallURL → https://gameograf.com/?utm_source=dekuy&utm_medium=dekuy (3rd-party tracking).
• install_url_hijack crx onInstalled opens https://gameograf.com/?utm_source=dekuy&utm_medium=dekuy (3rd-party tracking).
• csp_absent manifest content_security_policy is null; no CSP declared on MV3 extension with innerHTML sinks.
• dom_xss_sink crx innerHTML assignments from variables found in js/popup.js and js/calendar.js — DOM-XSS risk.
• search_permission manifest search permission declared alongside NewTab override — monetization surface for search hijack.
• no_verified_publisher store Developer dekuy.com / support@gameograf.com has no verified publisher badge and 14 installs.
• privacy_policy_scoped api Privacy policy fetched, scoped to extension, discloses collection/retention/3rd-party sharing — adequate.
• threat_feed_membership api Extension ID listed by TPCI chrome-mal-ids — Frieren blooming [adware] + malext.io malicious_extension_sentry; score 4.34 -> 6.84 (+2.5 cap 2.5).

Permissions Breakdown

• search medium Allows modifying search provider; medium risk on its own but paired with NewTab override amplifies monetization risk.
• host_permissions: https://api.gameograf.com/* low Scoped to developer's own API domain; limited blast radius.
• chrome_url_overrides.newtab high NewTab override gives persistent eyeball control and monetization surface on every new tab.
