Course 24 - Machine Learning for Red Team Hackers | Episode 1: Building an Automated CAPTCHA-Breaking Bot | CyberCode Academy

In this lesson, you’ll learn about:

How CAPTCHA systems (like Really Simple CAPTCHA for WordPress) are designed to prevent automated abuse
The role of reconnaissance in identifying security mechanisms on web applications (for defensive testing with permission)
How OpenCV is used in computer vision for:
- Grayscale conversion
- Image thresholding
- Noise reduction and morphological operations (e.g., dilation)
- Contour detection and character segmentation
The fundamentals of building a Convolutional Neural Network (CNN) using frameworks like Keras
Why preprocessing (normalization, resizing, padding) is critical for image-based ML accuracy
How browser automation tools such as Selenium function in legitimate contexts (e.g., QA testing, regression testing, accessibility testing)
Why CAPTCHA systems can be vulnerable to ML advances—and how modern defenses evolve in response

Defensive & Ethical Takeaway Instead of bypassing CAPTCHAs, security professionals use this knowledge to:

Strengthen bot mitigation strategies
Implement more resilient human verification systems
Detect automated abuse patterns
Transition toward modern solutions like behavioral analysis and risk-based authentication
