Top Risks

• Privacy policy URL unreachable (fetch_error) — no verifiable data handling disclosure for a NewTab extension.
• NewTab override with search permission = persistent monetization surface on every new tab open.
• Uninstall and install URL hijacking both present — tracks install/uninstall lifecycle to 3rd-party URLs.
• Privacy policy domain (haberikra.com) differs from developer domain (gameograf.com) — suspicious mismatch.
• innerHTML DOM-XSS sink in popup.js with no CSP; elevated risk if input is ever attacker-controlled.

Evidence

• newtab_override manifest chrome_url_overrides.newtab set to newtab.html — replaces every new tab with extension page.
• uninstall_url_hijack crx setUninstallURL points to gameograf.com with UTM tracking params.
• install_url_hijack crx onInstalled opens gameograf.com with UTM tracking params.
• privacy_policy_fetch_failed api Privacy policy at haberikra.com/privacy-policy/ returned HTTPError — cannot be evaluated.
• privacy_policy_domain_mismatch store Developer domain gameograf.com but privacy policy hosted on haberikra.com — unrelated domain.
• no_developer_name store developer_name field is empty string in listing.
• months_since_update_15 store Last updated June 2025, 15 months ago — falls in 12-24mo stale band.
• dom_xss_sink_no_csp crx innerHTML sink in popup.js; csp_present=false on MV3 extension increases DOM-XSS exploitability.

Permissions Breakdown

• search medium Allows querying browser search engine; combined with newtab override raises monetization risk.
• host_permissions: https://api.gameograf.com/* low Scoped to developer's own API domain; limited blast radius.
• chrome_url_overrides.newtab high Replaces new tab — primary vector for search monetization and persistent user exposure.
