Top Risks

• THREAT FEED: extension ID independently confirmed malicious by TPCI chrome-mal-ids — Dragon Ball Z Live Wallpaper [adware] + malext.io malicious_extension_sentry (+2.5, capped).
• Privacy policy is Google's generic policy — not scoped to this extension, admits data collection and third-party sharing (Privacy: 10.0).
• Uninstall + install URL hijacking to gameograf.com UTM links — classic monetization shell pattern.
• New-tab override enables persistent ad/search monetization on every browser open.
• No CSP (csp_present=false) combined with innerHTML DOM-XSS sinks in popup.js and calendar.js.

Evidence

• uninstall_url_hijack manifest chrome.runtime.setUninstallURL → https://gameograf.com/?utm_source=gameograf&utm_campaign=bg — monetization redirect.
• install_url_hijack manifest onInstalled opens https://gameograf.com/?utm_source=install&utm_campaign=bg — install redirect.
• newtab_override manifest chrome_url_overrides.newtab = newtab.html; every new tab controlled by extension.
• generic_privacy_policy store Privacy policy URL is Google's own policy; scope_extension=false, data_collection=true, third_party_sharing=true.
• no_csp crx content_security_policy is null; MV3 default applies but no explicit CSP with innerHTML sinks present.
• dom_xss_sinks crx innerHTML user-controlled assignments in js/popup.js and js/calendar.js without CSP hardening.
• developer_name_missing store developer_name is empty string; verified_publisher=true but no visible 'Offered by' attribution.
• webstore_monetization_pattern store NewTab + install/uninstall URL hijack + search override = monetization shell cluster.
• threat_feed_membership api Extension ID listed by TPCI chrome-mal-ids — Dragon Ball Z Live Wallpaper [adware] + malext.io malicious_extension_sentry; score 4.90 -> 7.40 (+2.5 cap 2.5).

Permissions Breakdown

• search medium Allows override/query of browser search; medium risk, consistent with NewTab category.
• host_permissions: https://api.gameograf.com/* medium Scoped to developer's own API; acceptable but enables data exfil to dev backend.
• chrome_url_overrides.newtab medium Replaces new-tab page — high user-surface reach, monetization vector.
