Top Risks

• THREAT FEED: extension ID independently confirmed malicious by TPCI chrome-mal-ids — Kpop Demon Hunters Live Wallpaper [adware] + malext.io malicious_extension_sentry (+2.5, capped).
• Privacy policy is Google's generic policy — does not scope to this extension; scores maximum privacy risk.
• Uninstall and install URL hijacks redirect users to developer site via UTM tracking — monetization shell pattern.
• NewTab override with 'search' permission is classic ad-monetization surface for a wallpaper extension.
• No CSP declared (MV3 still benefits from explicit policy); DOM-XSS sinks in popup.js and calendar.js without CSP protection.

Evidence

• uninstall_url_hijack manifest chrome.runtime.setUninstallURL points to gameograf.com with UTM params — monetization/tracking on uninstall.
• install_url_hijack manifest onInstalled opens gameograf.com with UTM params — tracks installs for monetization.
• newtab_override manifest chrome_url_overrides.newtab = newtab.html; wallpaper extension controls every new-tab page.
• generic_privacy_policy store Privacy policy URL is Google's own account policy — scope_extension=false, data_collection=true, third_party_sharing=true.
• no_developer_name store developer_name is empty string; only identifier is email support@gameograf.com.
• dom_xss_sinks_no_csp crx Two innerHTML-from-variable sinks in popup.js and calendar.js; csp_present=false amplifies XSS risk.
• dev_email_sibling_cluster api support@gameograf.com is associated with 7 extensions by dev_email dimension — operator cluster pattern.
• search_permission_newtab_combo manifest 'search' permission + newtab override for a wallpaper extension is a known ad-monetization fingerprint.
• threat_feed_membership api Extension ID listed by TPCI chrome-mal-ids — Kpop Demon Hunters Live Wallpaper [adware] + malext.io malicious_extension_sentry; score 5.47 -> 7.97 (+2.5 cap 2.5).

Permissions Breakdown

• search medium Allows search-provider manipulation; paired with newtab override amplifies monetization risk.
• chrome_url_overrides.newtab medium Replaces new-tab page; core delivery mechanism for this extension's content and monetization.
• host_permissions: https://api.gameograf.com/* low Scoped to developer's own API domain; contained but enables telemetry/data collection.
