SECUREBROWSER EXTENSION

Your browser is the primary gateway to the internet—and consequently, the primary attack vector for numerous security threats. From tracking scripts that monitor your every move to zero-day vulnerabilities targeting browser weaknesses, the modern web experience represents a significant security challenge.

The Lackadaisical SecureBrowser Extension provides comprehensive protection against these threats through a multi-layered security approach that safeguards your privacy, encrypts your data, and shields you from malicious content.

Protection Layers

How It Works: Anti-Fingerprinting

Digital fingerprinting allows websites to identify your browser based on its unique characteristics, even without cookies. Our anti-fingerprinting technology works by:

// Browser fingerprinting protection
function applyFingerprintProtection() {
  // Generate a consistent but unique canvas noise pattern
  const canvasNoise = generateCanvasNoise(getBrowserSeed());
  
  // Apply canvas fingerprint protection
  protectCanvasFingerprint(canvasNoise);
  
  // Normalize font rendering to prevent font fingerprinting
  normalizeFontRendering();
  
  // Spoof screen resolution within reasonable limits
  spoofScreenResolution(
    window.screen.width * randomRange(0.95, 1.05),
    window.screen.height * randomRange(0.95, 1.05)
  );
  
  // Randomize reported browser plugin data
  randomizePluginData();
  
  // Protect against WebRTC leaks
  preventWebRTCLeaks();
  
  // Normalize timezone reporting
  normalizeTimezone();
  
  // Report successful fingerprint protection
  console.log("Fingerprint protection active");
}

Quantum-Resistant Tunnel

While most security extensions rely on outdated cryptographic approaches, SecureBrowser implements cutting-edge post-quantum algorithms to secure your data:

1. Connection Authentication:

   Uses CRYSTALS-Dilithium signatures for quantum-resistant verification of secure endpoints.

2. Key Exchange:

   Implements CRYSTALS-Kyber for quantum-resistant key exchange, ensuring forward secrecy even against quantum attacks.

3. Data Encryption:

   Applies AES-256 with quantum-resistant key derivation to secure all transmitted data.

4. Integrity Verification:

   Uses quantum-resistant hash-based authentication to validate data integrity during transmission.

Script Sanitization

The Script Sanitizer module analyzes JavaScript before execution to identify potential threats:

// Simplified script sanitization implementation
function sanitizeScript(scriptContent) {
  // Check for known malicious patterns
  const maliciousPatterns = [
    /eval\s*\(/gi,
    /document\.cookie/gi,
    /\.innerHTML\s*=/gi,
    /new\s+Function\s*\(/gi,
    /crypto\.getRandomValues/gi,
    /navigator\.sendBeacon/gi
  ];
  
  // Check for cryptocurrency miners
  const minerPatterns = [
    /coinhive/gi,
    /cryptonight/gi,
    /minero/gi,
    /webassembly\.instantiate/gi
  ];
  
  // Check for canvas fingerprinting
  const fingerprintingPatterns = [
    /canvas\.toDataURL/gi,
    /getImageData/gi,
    /createImageData/gi
  ];
  
  // Log and block suspicious scripts
  for (const pattern of [...maliciousPatterns, ...minerPatterns, ...fingerprintingPatterns]) {
    if (pattern.test(scriptContent)) {
      // Report suspicious activity
      reportSuspiciousScript(pattern.toString(), scriptContent.substring(0, 100));
      
      // Return sanitized version or block entirely based on threat level
      return sanitizeOrBlock(scriptContent, pattern);
    }
  }
  
  return scriptContent;
}

Performance Impact

Unlike many security extensions that significantly slow down browsing, SecureBrowser is designed for minimal performance impact:
