Top Risks

• THREAT FEED: extension ID independently confirmed malicious by TPCI chrome-mal-ids — Nissan GT-R Cyberpunk Live Wallpaper [adware] + malext.io malicious_extension_sentry (+2.5, capped).
• Privacy policy is Google's own policy — not scoped to this extension; admits data collection and third-party sharing.
• New-tab override with uninstall URL hijack to gameograf.com and install URL hijack — monetization shell pattern.
• Operator fingerprint matches 44 other extensions by dev_email — large wallpaper/NewTab farm.
• Extension is 15 months stale (>12mo) with newtab override still active on all users.

Evidence

• newtab_override manifest chrome_url_overrides.newtab replaces new-tab page; search permission also declared.
• uninstall_url_hijack crx setUninstallURL → https://gameograf.com/?utm_source=gameograf&utm_medium=link&utm_campaign=bg
• install_url_hijack crx onInstalled opens https://gameograf.com/?utm_source=install&utm_medium=link&utm_campaign=bg
• generic_privacy_policy store Policy URL is Google's own account policy; scope_extension=false, data_collection=true, third_party_sharing=true.
• operator_farm api dev_email fingerprint shared with 44 other extensions; compound sibling_count=0 but large farm.
• maintenance_stale store 15 months since update; 6-12mo band → +3.5 maintenance score.
• dom_xss_sink crx innerHTML from variable in js/popup.js; no CSP present.
• no_developer_name store developer_name field is empty string; reduces accountability.
• threat_feed_membership api Extension ID listed by TPCI chrome-mal-ids — Nissan GT-R Cyberpunk Live Wallpaper [adware] + malext.io malicious_extension_sentry; score 4.84 -> 7.34 (+2.5 cap 2.5).

Permissions Breakdown

• search medium Allows reading/manipulating search queries; common in NewTab override patterns.
• host_permissions: https://api.gameograf.com/* low Scoped to developer's own API domain; limited blast radius.
• chrome_url_overrides.newtab medium Replaces new-tab page; high-touch surface used for wallpaper/search monetization.
