🔍 Native-X Virtualization: Level 3

[Eth3rnit3]

Let’s dive into Level 3: Native-X Virtualization, the most advanced and stealthy configuration designed for scenarios where maximum undetectability is required.

Description:
In Level 3, the browser runs in standard mode (non-headless) within a virtual display server like Xvfb (X Virtual Frame Buffer). This setup allows Chromate to use native mouse and keyboard control via FFI (Foreign Function Interface), bypassing the synthetic JavaScript events generated by CDP. This approach is closer to real user behavior, reducing the risk of detection by sophisticated anti-bot systems.

Configuration Example:
The setup for Level 3 requires running the browser with a virtual display server. You can use Xvfb for this purpose:

# Start Xvfb on display :99
Xvfb :99 -screen 0 1920x1080x24 &

# Set the DISPLAY environment variable
export DISPLAY=:99

In your Ruby script, the configuration remains similar, but native_control is enabled:

require 'chromate'

# Configuration for Level 3: Native-X Virtualization
Chromate.configure do |config|
  config.headless = false
  config.native_control = true # Enables FFI for native input control
end

browser = Chromate::Browser.new
browser.start

# Example of native mouse movement and interaction
browser.navigate_to('https://example.com')
button = browser.find_element('#native-button')
button.click_with_native_control
browser.screenshot_to_file('level3_screenshot.png')

browser.stop

Pros:

• Mimics real user interactions, bypassing CDP events that can trigger detection.
• Best suited for long-term automation tasks where maximum stealth is required.
• Uses native input control, improving the fidelity of mouse and keyboard actions.

Cons:

• Requires a virtual display server setup (e.g., Xvfb), adding complexity to the environment.
• Precise DOM-to-screen mapping can be challenging, especially with different screen resolutions and DPI settings.
• Higher resource usage due to running in non-headless mode.

Discussion Points:

• How do you handle the challenges of screen resolution and DPI mapping in virtual environments?
• Have you experienced issues with native input control via FFI? If so, what workarounds have you used?
• Any suggestions for improving synchronization between the virtual display and browser DOM elements?
