Browser Fingerprint Spoofing Explained: How KeLAAX Defeats Detection

Browser fingerprinting is one of the most sophisticated methods websites use to identify and track visitors. Understanding how it works is essential for anyone serious about undetectable traffic generation.

Did You Know? A browser fingerprint can contain over 50 unique data points, making it nearly as unique as a human fingerprint. Over 99% of browsers have a unique fingerprint.


What is Browser Fingerprinting?

Browser fingerprinting collects information about your browser and device to create a unique identifier. Unlike cookies, fingerprints can't be easily cleared and work across sessions.

Major Fingerprint Vectors

Understanding each fingerprint vector is crucial for defeating detection systems.

Canvas Fingerprinting

Websites draw hidden images on an HTML5 canvas element. Due to hardware and software differences, each system renders the image slightly differently, creating a unique hash.

How It Works

  1. Website creates an invisible canvas element
  2. JavaScript draws complex shapes and text
  3. The toDataURL() method extracts pixel data
  4. A hash is generated from the rendering differences

Technical Note: Even identical GPUs can produce different canvas fingerprints due to driver versions, font rendering settings, and anti-aliasing configurations.

How KeLAAX Defeats It

Our canvas spoofing injects subtle, consistent noise into canvas operations. This creates a unique but stable fingerprint that matches our profile database.


WebGL Fingerprinting

Similar to canvas, WebGL fingerprinting analyzes how your GPU renders 3D graphics. It can reveal your graphics card model and driver version.

GPU RendererWEBGL_debug_renderer_info

Shader PrecisiongetShaderPrecisionFormat()

How KeLAAX Defeats It

We spoof WebGL renderer and vendor strings while injecting noise into rendered output. Each profile has consistent WebGL characteristics that match real hardware configurations.


Audio Context Fingerprinting

The Web Audio API can be used to analyze how your system processes audio signals, creating another unique identifier.

The Fingerprinting Process
  1. Create an oscillator with specific frequency
  2. Process through dynamics compressor
  3. Analyze output with AnalyserNode
  4. Hash the frequency data

How KeLAAX Defeats It

KeLAAX modifies audio processing output with imperceptible noise while maintaining profile consistency.


Font Fingerprinting

By measuring which fonts are available on your system, websites can narrow down your operating system and installed applications.

Font Detection: Websites can probe for thousands of fonts in milliseconds using JavaScript. The specific combination of installed fonts creates a unique signature.

How KeLAAX Defeats It

Our profiles include curated font lists that match typical system configurations for each simulated platform.


Hardware Fingerprinting

This includes screen resolution, color depth, device memory, CPU cores, and other hardware characteristics.

How KeLAAX Defeats It

Each profile includes realistic hardware specifications based on real-world device populations. Values are consistent across sessions for the same profile.


The Importance of Consistency

Many fingerprint spoofers fail because they randomize values on every page load. This inconsistency is itself a detection signal.

Critical Insight: Randomization on every page load is a bigger red flag than having a suspicious fingerprint. Real hardware doesn't change between page loads!

KeLAAX Consistency Features

KeLAAX Stealth maintains consistent fingerprints across:

  • ✅ Page navigations within a session
  • ✅ Tab switches and focus changes
  • ✅ Session restarts (when using the same profile)
  • ✅ Form submissions and AJAX requests

Testing Your Fingerprint

Before running campaigns, always test your fingerprint configuration.
