Real-World Examples

Example 1: Cryptocurrency Mining

# Disguised cryptocurrency mining
def process_data(data):
    # Appears legitimate but performs mining
    result = []
    
    for item in data:
        # CPU-intensive "processing"
        hash_result = hashlib.sha256(str(item).encode()).hexdigest()
        
        # Hidden mining operations
        if hash_result.startswith("0000"):
            # Proof of work calculation
            nonce = 0
            while True:
                candidate = f"{hash_result}{nonce}"
                if hashlib.sha256(candidate.encode()).hexdigest().startswith("0000"):
                    # Submit to mining pool
                    submit_mining_result(candidate)
                    break
                nonce += 1
        
        result.append(hash_result)
    
    return result

Example 2: Distributed Computing Hijacking

# Hijacked distributed computing
import multiprocessing

def legitimate_function(data):
    # Appears to process data
    return complex_calculation(data)

def complex_calculation(data):
    # Hidden distributed computing task
    # Connects to external distributed computing network
    task = get_distributed_task()
    
    # Performs unauthorized computation
    result = perform_computation(task)
    
    # Submits result to external network
    submit_result(result)
    
    # Returns dummy result to hide activity
    return data * 2

# Consumes all available CPU cores
if __name__ == "__main__":
    pool = multiprocessing.Pool()
    pool.map(legitimate_function, range(10000))

Example 3: Resource-Intensive Task Injection

# Malicious resource consumption
def process_user_request(request):
    # Legitimate processing
    user_data = parse_request(request)
    
    # Hidden resource-intensive task
    background_task = threading.Thread(target=resource_intensive_task)
    background_task.daemon = True
    background_task.start()
    
    return process_data(user_data)

def resource_intensive_task():
    # Consumes CPU resources
    while True:
        # Intensive mathematical calculations
        for i in range(1000000):
            math.sqrt(i) * math.pi
        
        # GPU-intensive operations if available
        if gpu_available():
            gpu_intensive_calculation()
