đŸ’ģ Tools Used for Password Cracking:

  • John the Ripper
  • Hashcat
  • Hydra
  • Medusa
  • Crunch

đŸ”Ĩ Example: Crack Password using Hydra

📌 Hydra āĻŦ্āϝāĻŦāĻšাāϰ āĻ•āϰে āφāĻŽāϰা āϝেāĻ­াāĻŦে āĻŦ্āϰুāϟāĻĢোāϰ্āϏ āĻ…্āϝাāϟাāĻ• āϚাāϞাāχ:

hydra -l admin -P /usr/share/wordlists/rockyou.txt 192.168.0.1 http-get /login

Explanation:

  • -l admin: Target username
  • -P: Password list path
  • 192.168.0.1: Target IP
  • http-get /login: Login form path

đŸ§Ē Practice Task for You:

  1. ✅ Install hydra or john in your Kali Linux.
  2. ✅ Download a password list (e.g., rockyou.txt).
  3. ✅ Setup a local login page (e.g., DVWA).
  4. ✅ Try dictionary & brute-force attacks safely on your own system.

📌 Tips:

  • 🛑 Don’t attack real websites. Practice only in legal lab environments.
  • 🧠 Learn how hashing works (MD5, SHA1, etc.)
  • 💡 Try john --wordlist for password file cracking.
