Top Risks

• NewTab override with uninstall URL hijack and install URL hijack — classic monetization/traffic shell pattern.
• Uninstall and install URL hijacking both confirmed, pointing to gameograf.com with tracking params.
• No developer name disclosed; verified publisher but anonymous presentation.
• dom_sink_innerhtml_userctrl in calendar.js with no CSP — DOM-XSS risk.
• Privacy policy discloses third-party data sharing; retention and collection confirmed.

Evidence

• newtab_override manifest chrome_url_overrides.newtab set to newtab.html — replaces every new tab.
• uninstall_url_hijack crx setUninstallURL to gameograf.com with UTM tracking params confirmed.
• install_url_hijack crx onInstalled opens gameograf.com with UTM tracking params.
• no_csp manifest content_security_policy is null; MV3 default applies but no explicit hardening.
• dom_xss_sink crx innerHTML assigned from variable in js/calendar.js without sanitization.
• verified_publisher store verified_publisher == true; domain resolves and is not throwaway.
• privacy_policy_third_party_sharing api Privacy policy confirms data collection, retention, and third-party sharing.
• no_developer_name store developer_name is empty string; reduces accountability signal.

Permissions Breakdown

• search medium Allows reading/modifying search provider; paired with newtab override raises monetization concern.
• alarms low Schedules background tasks; low standalone risk.
• storage low Local data persistence; low risk.
• host_permissions: https://api.gameograf.com/* low Scoped to developer's own API domain; no broad host access.
• chrome_url_overrides: newtab medium Replaces new tab page; primary delivery vector for monetization/data collection.
