Python Ethical Hacking - WEB PENETRATION TESTING(1)

WHAT IS A WEBSITE

• Computer with OS and some servers.
• Apache, MySQL ...etc.
• Cotains web application.
• PHP, Python ...etc.
• Web application is executed here and not on the client's machine.

How to hack a website？

• An application installed on a computer.
• ->web application pentesting
• Computer uses an OS + other applications.
• ->server side attacks.
• Managed by humans.
• ->client side attacks.

 INFORMATION GATHERING

• IP address.
• Domain name info.
• Technologies used.
• Other websites on the same server.
• DNS records.
• Files, sub-domains, directories.

CRAWLING SUBDOMAINS

• Domains before the actual domain name.
• Part of the main domain.

Ex:

• subdomain.target.com
• mail.google.com
• plus.google.com

#!/usr/bin/env python

import requests
url = "baidu.com"
try:
    get_response = requests.get("http://" + url)
    print(get_response)
except requests.exceptions.ConnectionError:
    pass

 Polished Python Code:

#!/usr/bin/env python

import requests


def request(url):
    try:
        return requests.get("http://" + url)
    except requests.exceptions.ConnectionError:
        pass


target_url = "baidu.com"

with open("subdomains.list", "r") as wordlist_file:
    for line in wordlist_file:
        word = line.strip()
        test_url = word + "." + target_url
        response = request(test_url)
        if response:
            print("[+] Discovered subdomain --> " + test_url)
