Top Risks

• THREAT FEED: extension ID independently confirmed malicious by TPCI chrome-mal-ids — Deadpool Live Wallpaper New Tab [adware] + malext.io malicious_extension_sentry (+2.5, capped).
• Privacy policy URL unreachable (fetch error) — no verifiable data handling disclosure for a NewTab extension.
• Uninstall and install URL hijack to gameograf.com — classic traffic-monetization shell pattern.
• NewTab override replaces every new tab; combined with search permission creates ad-monetization surface.
• Two innerHTML DOM-XSS sinks with no CSP present — elevated DOM-XSS risk on new tab page.

Evidence

• privacy_policy_fetch_failed api Privacy policy URL returns HTTPError; policy cannot be evaluated — treated as unfetched (+10.0 privacy).
• uninstall_url_hijack crx chrome.runtime.setUninstallURL → https://gameograf.com/?utm_source=gameograf&utm_medium=link&utm_campaign=bg&utm_content=uninstall
• install_url_hijack crx onInstalled opens https://gameograf.com/?utm_source=install&utm_medium=link&utm_campaign=bg&utm_content=install
• newtab_override manifest chrome_url_overrides.newtab present — replaces every new tab page for all users.
• dom_xss_no_csp crx Two innerHTML user-ctrl sinks in popup.js and calendar.js; csp_present=false amplifies risk to +2.0 each.
• no_developer_name store developer_name is empty string; no verified publisher badge — reduced accountability.
• search_engine_count_ok api Only 1 search engine (google.com) seen — multi-search-engine anomaly rule not triggered.
• domain_age_ct api gameograf.com first cert 2021-02-03 (age_days=2051, cert_count=265) — not a new/throwaway domain.
• threat_feed_membership api Extension ID listed by TPCI chrome-mal-ids — Deadpool Live Wallpaper New Tab [adware] + malext.io malicious_extension_sentry; score 5.41 -> 7.91 (+2.5 cap 2.5).

Permissions Breakdown

• search medium Allows querying browser search provider; relevant to NewTab monetization pattern.
• host_permissions: https://api.gameograf.com/* low Scoped to dev-owned API domain only.
• chrome_url_overrides.newtab medium Replaces every new tab — high reach, core monetization surface for this category.
