Top Risks

• THREAT FEED: extension ID independently confirmed malicious by TPCI chrome-mal-ids — Jujutsu Kaisen Satoru Gojo Live Wallpaper [adware] + malext.io malicious_extension_sentry (+2.5, capped).
• NewTab override with search permission — classic monetization/search-hijack surface.
• Uninstall and install URL hijacks redirect to developer tracking endpoints.
• No CSP on MV3 extension with innerHTML DOM-XSS sinks in popup and calendar.
• No developer name listed; verified publisher discount partially offsets opacity.

Evidence

• newtab_override manifest chrome_url_overrides.newtab = newtab.html; paired with 'search' permission — monetization pattern.
• uninstall_url_hijack crx setUninstallURL → gameograf.com with UTM tracking params.
• install_url_hijack crx onInstalled opens gameograf.com with UTM install tracking params.
• csp_absent manifest csp_present=false on MV3 extension with innerHTML sinks; +2.0 webstore stale/CVE not triggered but code risk elevated.
• dom_sink_innerhtml crx Two innerHTML sinks (popup.js, calendar.js) with no CSP — DOM-XSS risk.
• verified_publisher store Verified publisher badge present; discounts reputation pillar.
• privacy_policy api Policy fetched, scoped to extension, discloses data collection, retention, third-party sharing.
• js_external_hosts crx 12 external JS hosts including api.gameograf.com and multiple Google services.
• threat_feed_membership api Extension ID listed by TPCI chrome-mal-ids — Jujutsu Kaisen Satoru Gojo Live Wallpaper [adware] + malext.io malicious_extension_sentry; score 3.15 -> 5.65 (+2.5 cap 2.5).

Permissions Breakdown

• search medium Allows reading/modifying search queries; combined with newtab override raises monetization concern.
• host_permission: https://api.gameograf.com/* low Scoped to developer's own API domain; limited blast radius.
• chrome_url_overrides.newtab medium Replaces new-tab page; primary surface for monetization and search redirection.
