Top Risks

• THREAT FEED: extension ID independently confirmed malicious by TPCI chrome-mal-ids — Kaneki Unleashed Tokyo Ghoul Live Wallpaper [adware] + malext.io malicious_extension_sentry (+2.5, capped).
• Privacy policy is Google's generic policy — does not scope to this extension; admits data collection and third-party sharing (v3.5-D → +10.0 privacy).
• New-tab override with install/uninstall URL hijack to gameograf.com: classic monetization shell pattern.
• Uninstall URL hijack confirmed: redirects to gameograf.com with UTM tracking on removal.
• Two DOM-XSS innerHTML sinks with no CSP present — elevated risk under v3 FIX B.

Evidence

• newtab_override manifest chrome_url_overrides.newtab set to newtab.html — replaces new-tab page for all sessions.
• uninstall_url_hijack crx setUninstallURL → https://gameograf.com/?utm_source=gameograf&utm_medium=link&utm_campaign=bg&utm_content=uninstall
• install_url_hijack crx onInstalled opens https://gameograf.com/?utm_source=install&utm_medium=link&utm_campaign=bg&utm_content=install
• privacy_policy_generic store Policy URL is myaccount.google.com/privacypolicy — Google's own policy, not scoped to this extension; data_collection=true, third_party_sharing=true.
• dom_xss_no_csp crx 2× innerHTML sinks in popup.js and calendar.js; csp_present=false amplifies DOM-XSS risk per v3 FIX B.
• no_developer_name store developer_name is empty string despite verified_publisher=true.
• new_tab_monetization manifest search permission + newtab override + install/uninstall UTM hooks = monetization-shell fingerprint.
• verified_publisher store verified_publisher=true for gameograf.com; domain resolves, not throwaway — partial reputation credit.
• threat_feed_membership api Extension ID listed by TPCI chrome-mal-ids — Kaneki Unleashed Tokyo Ghoul Live Wallpaper [adware] + malext.io malicious_extension_sentry; score 5.44 -> 7.94 (+2.5 cap 2.5).

Permissions Breakdown

• search medium Allows reading/modifying search engine; combined with newtab override is a monetization surface.
• host_permission: https://api.gameograf.com/* low Scoped to developer's own API domain only.
• chrome_url_overrides.newtab medium Replaces new-tab page; high-visibility hijack enabling persistent monetization/tracking.
