CLASSROOM CYBER RANGE

Watch a Wi-Fi password get cracked — step by step.

A guided, fully-simulated walkthrough of a WPA2 handshake capture: enable monitor mode, scan the air, knock a device offline, catch the 4-way handshake as it reconnects, then recover the passphrase with a wordlist.

Training use only. No radios are touched and no real network exists — every packet, device, and password on this screen is scripted for teaching how these attacks work and how to defend against them.

Network compromised — in simulation

You just reproduced every stage of an offline WPA2 dictionary attack.

◇ WHAT JUST HAPPENED

  • 01Monitor mode put the adapter into listen-to-everything mode.
  • 02airodump-ng mapped nearby access points and their channels.
  • 03Locking the target revealed the phone connected to it.
  • 04Deauth frames forced the phone off the network.
  • 05On reconnect, the 4-way handshake was captured to a .cap file.
  • 06aircrack-ng tried wordlist guesses offline until one matched.

◇ HOW TO DEFEND

  • Use a long, random passphrase. The attack only works if the password is in a wordlist — 16+ random characters never is.
  • Upgrade to WPA3 (SAE). It kills offline dictionary attacks: a captured handshake can't be brute-forced.
  • Enable 802.11w / Protected Management Frames. This blocks the deauth trick that forces reconnects.
  • Turn off WPS and keep router firmware current.
