Top Risks

• THREAT FEED: extension ID independently confirmed malicious by TPCI chrome-mal-ids — Jujutsu Kaisen Sukuna [adware] + malext.io malicious_extension_sentry (+2.5, capped).
• NewTab override with uninstall/install URL hijack — classic monetization shell pattern.
• Privacy policy URL returns fetch error; no enforceable data handling disclosure.
• Operator cluster: 18 sibling extensions under same dev email, 16 sharing install URL pattern.
• DOM-XSS sinks (innerHTML) in popup.js and calendar.js with no CSP guard.

Evidence

• uninstall_url_hijack manifest chrome.runtime.setUninstallURL points to gameograf.com UTM-tracked URL — monetization signal.
• install_url_hijack manifest onInstalled opens gameograf.com UTM-tracked URL — monetization shell pattern.
• operator_cluster api 18 sibling extensions share same dev email; 16 share install URL; compound fingerprint matches 2 others.
• privacy_policy_fetch_error api Privacy policy URL returned HTTPError; policy could not be evaluated — treated as unfetched.
• newtab_override manifest chrome_url_overrides.newtab set to newtab.html — replaces every new tab page.
• dom_xss_sinks crx innerHTML assignments from variables in popup.js and calendar.js; no CSP to mitigate.
• verified_publisher store Verified publisher badge present but discount capped at -1.0 per v3.5 rule E (monetization cluster).
• domain_age api gameograf.com first cert 2021-02-03 (age ~2050d, 265 certs); not new, resolves fine.
• threat_feed_membership api Extension ID listed by TPCI chrome-mal-ids — Jujutsu Kaisen Sukuna [adware] + malext.io malicious_extension_sentry; score 5.49 -> 7.99 (+2.5 cap 2.5).

Permissions Breakdown

• search medium Can alter search provider; medium risk.
• host_permissions: https://api.gameograf.com/* low Scoped to dev's own API domain only.
• chrome_url_overrides.newtab medium Replaces new tab page — primary monetization surface for this category.
