Anti-Debugger Bypass

A powerful Chrome extension to bypass common anti-debugging scripts and DevTools traps.

Installation • Features • Usage • Contributing

📖 Overview

Anti-Debugger Bypass is a lightweight Google Chrome extension designed to neutralize common client-side JavaScript anti-debugging techniques. By injecting a script at document_start, this extension intercepts and neutralizes traps designed to crash or halt your browser's Developer Tools (DevTools).

Whether you're a security researcher, a penetration tester, or just trying to inspect elements without being interrupted by infinite debugger statements, this extension ensures a smooth debugging experience.

✨ Features

• 🛑 Eval Debugger Block: Intercepts and neutralizes eval("debugger").
• 🛡️ Safe Function Constructor: Patches window.Function to prevent Function("debugger")() calls cleanly across multiple layers.
• ⏱️ SetInterval Protection: Blocks malicious loops using setInterval that execute debugger or eval.
• 🔗 Redirect Prevention: Prevents aggressive anti-debug scripts from redirecting location.href away from the current page.
• 📴 Console Tamper Protection: Temporarily disables console output clearing (console.clear) and timing checks during page load, restoring them automatically afterward.
• 🔐 CSP Enforcement: Uses a Content-Security-Policy meta tag to help neutralize inline eval payloads.
