Top Risks

• NewTab override with install+uninstall URL hijacks pointing to gameograf.com tracking URLs — monetization shell pattern.
• Uninstall and install URL hijack to 3rd-party tracking URLs (utm_source=extension/lofi).
• Two DOM-XSS innerHTML sinks with no CSP — exploitable if API data is attacker-controlled.
• No developer name listed; verified publisher but anonymous identity.
• Search permission combined with newtab override enables undisclosed search monetization.

Evidence

• newtab_override manifest chrome_url_overrides.newtab set to newtab.html — full new-tab replacement.
• uninstall_url_hijack crx setUninstallURL targets https://gameograf.com/?utm_source=extension&utm_medium=install
• install_url_hijack crx onInstalled opens https://gameograf.com/?utm_source=lofi&utm_medium=install
• dom_xss_sink crx innerHTML assigned from variable in popup.js and calendar.js with csp_present=false.
• no_csp manifest content_security_policy is null; MV3 defaults apply but no explicit hardening.
• verified_publisher store Developer is verified publisher at gameograf.com which resolves and is not throwaway.
• privacy_policy api Policy fetched, scoped to extension, discloses data collection, retention, and 3rd-party sharing.
• low_installs store Only 11 installs; tail-install pattern but no high-tier permissions detected.

Permissions Breakdown

• search medium Can manipulate search queries/provider; relevant for NewTab monetization.
• host_permissions: https://api.gameograf.com/* low Scoped to dev's own API domain; low blast radius.
• chrome_url_overrides.newtab medium Replaces new-tab page; primary vector for search monetization.
