Top Risks

• NewTab override replaces every new tab — persistent high-reach monetization surface for 302+ users.
• Privacy policy is Google's own account policy, not scoped to this extension; admits data collection and 3rd-party sharing.
• Uninstall and install URL hijacking redirect users to gameograf.com marketing pages.
• No developer name listed; generic email identity reduces accountability.
• innerHTML DOM-XSS sink in popup.js with no CSP, raising exploitation risk.
