Lab 01 - Challenge Lab 02 - SSH Brute Forcer - Learn how to build an SSH brute forcer to crack weak passwords. Lab 02 - Challenge Lab 03 — ARP Spoofer - Learn how to build an ARP spoofer to intercept network traffic.

Before any data is exchanged, two hosts must agree to talk. This agreement is called the three-way handshake: A port scanner exploits this: if the server replies with a SYN-ACK, the port is open. If it replies with RST (reset), the port is closed. If there is no reply at all, the port is likely filtered by a firewall. https://teknolabs.net/courses/python/python-ethical-hacking/lab_01_port_scanner_challenges/index.html Mon, 01 Jan 0001 00:00:00 +0000 https://teknolabs.net/courses/python/python-ethical-hacking/lab_01_port_scanner_challenges/index.html ⚠️ Avertissement légal & éthique : exécutez ces exercices uniquement sur vos propres machines/VMs ou sur des environnements dédiés au lab avec autorisation explicite. Le port‑scanning et la collecte d’informations sur des systèmes tiers sans accord sont illégaux. Exercice 1 — Premiers pas avec socket Objectif : créer une connexion TCP simple en Python. Énoncé : Écrivez une fonction tcp_connect(host, port) qui tente d’ouvrir une connexion TCP vers host:port et retourne True si la connexion réussit, False sinon. https://teknolabs.net/courses/python/python-ethical-hacking/lab_02_ssh_brute_forcer/index.html Mon, 01 Jan 0001 00:00:00 +0000 https://teknolabs.net/courses/python/python-ethical-hacking/lab_02_ssh_brute_forcer/index.html Ethical Hacking with Python ⚠️ This tool must only be used against systems you own or have written permission to test. Brute-forcing SSH without permission is a criminal offence. Use Metasploitable 2 in a local VM, or your own machine with SSH enabled. What is a Brute Force Attack? A brute force attack is simple: try many passwords, one after the other, until one works. It succeeds because people choose weak, predictable passwords. https://teknolabs.net/courses/python/python-ethical-hacking/lab_02_ssh_brute_forcer_challenges/index.html Mon, 01 Jan 0001 00:00:00 +0000 https://teknolabs.net/courses/python/python-ethical-hacking/lab_02_ssh_brute_forcer_challenges/index.html ⚠️ Avertissement légal & éthique — Tout essai d’authentification doit être réalisé exclusivement sur vos propres machines/VMs ou un lab explicitement autorisé. Ne lancez jamais ces scripts sur des systèmes tiers. Exercice 1 — Installation & vérification de Paramiko Objectif : vérifier l’environnement Python/Paramiko. Énoncé : Installez Paramiko. Affichez sa version. Indices : pip install paramiko; python3 -c "import paramiko; print(paramiko.__version__)". Exercice 2 — Sonde d’authentification SSH minimaliste Objectif : distinguer success / failure / error. https://teknolabs.net/courses/python/python-ethical-hacking/lab_03_arp_spoofer/index.html Mon, 01 Jan 0001 00:00:00 +0000 https://teknolabs.net/courses/python/python-ethical-hacking/lab_03_arp_spoofer/index.html Ethical Hacking with Python ⚠️ This lab must only be run inside an isolated virtual network you fully control. ARP spoofing on any network you do not own is a criminal offence. Use Host-Only or Internal networking in VirtualBox/VMware — never connect your lab VMs to the internet or a real LAN. What is ARP and Why is it Vulnerable? When your computer wants to send data to another machine on the same network, it needs two things: the destination’s IP address (which you usually know) and its MAC address (the physical hardware address, which you don’t always know). https://teknolabs.net/courses/python/python-ethical-hacking/lab_03_arp_spoofer_challenges/index.html Mon, 01 Jan 0001 00:00:00 +0000 https://teknolabs.net/courses/python/python-ethical-hacking/lab_03_arp_spoofer_challenges/index.html ⚠️ Avertissement légal & éthique — L’ARP spoofing perturbe le réseau et peut intercepter du trafic. N’exécutez ces exercices que sur un réseau de lab isolé (Host‑Only / Internal) que vous contrôlez intégralement. Jamais sur un réseau tiers (université, travail, domicile connecté à Internet). Exercice 1 — OSI (rappel ciblé) Objectif : situer ARP par rapport aux couches 2/3. Énoncé : En 3–5 lignes, expliquez pourquoi ARP « relie » IP (couche 3) et Ethernet (couche 2).
