Top Risks

• THREAT FEED: extension ID independently confirmed malicious by TPCI chrome-mal-ids — FC Barcelona Emblem Live Wallpaper [adware] + malext.io malicious_extension_sentry (+2.5, capped).
• NewTab override replaces every new tab — persistent high-reach monetization surface with install/uninstall URL hijacks.
• Privacy policy is Google's own account policy; does not scope data collection to this extension at all (+10.0 privacy).
• Uninstall and install URL hijacks redirect to gameograf.com with UTM tracking — monetization shell pattern.
• Two DOM-XSS sinks (innerHTML from variable) with no CSP present elevate code quality risk.

Evidence

• newtab_override manifest chrome_url_overrides.newtab set to newtab.html — replaces new tab page on every open.
• install_url_hijack manifest onInstalled opens https://gameograf.com/?utm_source=Barcelona&utm_medium=install (+2.0 webstore).
• uninstall_url_hijack manifest setUninstallURL points to https://gameograf.com/?utm_source=extension&utm_medium=install (+3.0 webstore).
• generic_privacy_policy api Privacy policy URL is Google Account policy; scope_extension=false, data_collection=true, third_party_sharing=true → +10.0 privacy (D rule).
• no_csp manifest content_security_policy is null; csp_present=false. Elevates innerHTML DOM-XSS sink severity.
• dom_xss_sinks crx Two dom_sink_innerhtml_userctrl findings in popup.js and calendar.js with no CSP → +2.0 code quality.
• no_developer_name store developer_name is empty string; reduces accountability; +1.0 reputation.
• newtab_single_search_engine api search_engine_count=1 (google.com); does not trigger multi-search-engine anomaly.
• threat_feed_membership api Extension ID listed by TPCI chrome-mal-ids — FC Barcelona Emblem Live Wallpaper [adware] + malext.io malicious_extension_sentry; score 5.18 -> 7.68 (+2.5 cap 2.5).
