Top Risks

• NewTab override replaces every new tab — high-traffic monetization surface with uninstall/install URL hijacks.
• Uninstall and install URL hijacks redirect to developer site with UTM tracking on every install/removal.
• No developer name listed; 'Offered by' field empty increases accountability gap.
• dom_sink_innerhtml_userctrl in calendar.js without CSP creates DOM-XSS risk.
• search permission combined with NewTab override allows interception of user search queries.

Evidence

• newtab_override manifest chrome_url_overrides.newtab set to newtab.html — replaces every new-tab page for all users.
• uninstall_url_hijack crx setUninstallURL targets https://gameograf.com/?p=32976?utm_source=extension&utm_medium=uninstall
• install_url_hijack crx onInstalled opens https://gameograf.com/?p=32976?utm_source=extension&utm_medium=install
• no_csp manifest content_security_policy is null; MV3 provides defaults but no explicit hardening.
• dom_xss_sink crx innerHTML assigned from variable in js/calendar.js without sanitization.
• verified_publisher store Developer has verified publisher badge; domain gameograf.com resolves, no throwaway signals.
• privacy_policy_adequate api Policy scoped to extension, discloses data collection, retention, and third-party sharing.
• no_developer_name store developer_name field is empty string; 'Offered by' attribution missing.

Permissions Breakdown

• search medium Can read search queries; elevated for a NewTab/wallpaper extension.
• alarms low Schedules background tasks; low standalone risk.
• storage low Persists local settings; standard low-risk API.
• chrome_url_overrides.newtab medium Replaces new-tab page; core vector for traffic monetization.
• host_permissions: https://api.gameograf.com/* low Scoped to developer's own API domain; limited reach.
