Top Risks

• THREAT FEED: extension ID independently confirmed malicious by TPCI chrome-mal-ids — Unleash the King of Curses with Sukuna Live Wallpaper [adware] + malext.io malicious_extension_sentry (+2.5, capped).
• NewTab override replaces every tab with anime wallpaper page — persistent search monetization surface.
• Uninstall and install URL hijacks track user lifecycle via UTM parameters to gameograf.com.
• No CSP present (MV3 null) with innerHTML DOM-XSS sink in calendar.js.
• Missing developer name reduces accountability; no 'Offered by' field visible.

Evidence

• newtab_override manifest chrome_url_overrides.newtab = newtab.html — replaces every new tab page.
• uninstall_url_hijack crx setUninstallURL targets https://gameograf.com/?p=33449?utm_source=extension&utm_medium=uninstall.
• install_url_hijack crx onInstalled opens https://gameograf.com/?p=33449?utm_source=extension&utm_medium=install.
• no_csp manifest content_security_policy is null; MV3 default CSP applies but no explicit hardening.
• dom_xss_sink crx calendar.js assigns innerHTML from variable; DOM-XSS risk with no CSP.
• developer_name_missing store developer_name is empty string; no 'Offered by' attribution for accountability.
• broad_js_hosts crx 12 external JS hosts including api.gameograf.com and multiple Google service domains.
• verified_publisher store verified_publisher=true; caps reputation discount but newtab+hijack limits its weight.
• threat_feed_membership api Extension ID listed by TPCI chrome-mal-ids — Unleash the King of Curses with Sukuna Live Wallpaper [adware] + malext.io malicious_extension_sentry; score 4.27 -> 6.77 (+2.5 cap 2.5).

Permissions Breakdown

• search medium Can read search queries; combined with newtab override elevates monetization risk.
• alarms low Schedules background tasks; low standalone risk.
• storage low Persists local data; standard utility permission.
• chrome_url_overrides.newtab high Replaces every new tab — prime real estate for search monetization and tracking.
