Top Risks

• THREAT FEED: extension ID independently confirmed malicious by TPCI chrome-mal-ids — Girl With Headphones Working In Room Live Wallpaper [adware] + malext.io malicious_extension_sentry (+2.5, capped).
• NewTab override hijacks every new tab; uninstall+install URL hijack redirects users to gameograf.com on every lifecycle event.
• No developer name listed; low-install (14) unknown operator with monetization-oriented URL tracking parameters.
• Two innerHTML DOM-XSS sinks (popup.js, calendar.js) with no CSP in place — exploitable if API responses are ever compromised.
• Extension contacts 12 external JS hosts including chat.openai.com, Google Workspace apps — broad JS reach beyond stated wallpaper function.

Evidence

• newtab_override manifest chrome_url_overrides.newtab set to newtab.html — every new tab replaced.
• uninstall_url_hijack crx setUninstallURL → https://gameograf.com/?utm_source=extension&utm_medium=install
• install_url_hijack crx onInstalled opens https://gameograf.com/?utm_source=extension&utm_medium=install
• no_developer_name store developer_name is empty string; identity unverified.
• dom_xss_sinks_no_csp crx innerHTML used in popup.js and calendar.js with csp_present==false — DOM-XSS risk.
• broad_js_external_hosts crx 12 external JS hosts contacted including chat.openai.com, Google Workspace — beyond wallpaper function.
• privacy_policy_scoped api Policy fetched; scope_extension=true, data_collection=true, retention=true, third_party_sharing=true.
• low_install_count store Only 14 installs; minimal community vetting, tail-attack-surface candidate.
• threat_feed_membership api Extension ID listed by TPCI chrome-mal-ids — Girl With Headphones Working In Room Live Wallpaper [adware] + malext.io malicious_extension_sentry; score 4.29 -> 6.79 (+2.5 cap 2.5).

Permissions Breakdown

• search medium Allows reading/manipulating search queries; medium risk for a NewTab extension.
• host_permissions: https://api.gameograf.com/* medium Scoped to developer's own API domain; needed for wallpaper/config fetch.
• chrome_url_overrides.newtab medium Replaces every new tab with extension page — high reach, monetization surface.
