WiFi Hacking

  • Today we are looking at how to hack WiFi networks in a (semi) realistic environment
  • We have looked at the different types of security on networks
    • Open, WEP, WPA
  • And some of the different attacks available
    • Recovering passwords, password cracking, deauthentication, etc.
  • Now its your turn to have a go at hacking a network!

aircrack-ng

  • A suite of WiFi hacking tools
  • Usually entire suite in your package manager as 'aircrack-ng'
  • Alternatively download from their site
  • Tools included:
    • airmon-ng: Switch NIC to monitor mode
    • airodump-ng: Capture packets (and save them if requested)
    • aireplay-ng: Inject packets (de-auth, replay)
    • aircrack-ng: Crack password from captured packets

Wireshark

  • GUI application for viewing network traffic and packets
  • Hopefully you will have used this before in network forensics

Setup today

  • We have a WPA2 network running - SSID: cool_secure_afnom_network
  • It's up to you to hack it!
  • There is a device connecting/connected to this network
  • If you are deauthing ONLY DEAUTH THIS DEVICE NOT THE WHOLE NETWORK
    • If you knock over the whole network the finite amount of monkeys will be released to get you!
  • We have some USB NICs if your laptop cannot going into monitor mode but also feel free to work together!

Challenges

  • There aren't any specific challenges for today
  • Have a play around with monitor mode!
  • Try hacking the network we have set up!
  • See if you can crack the password!
  • You could even set up your own hotspot/network if you want to try something specific or at home!

Take a look at the network with monitor mode, try and hack it, and have some fun!

Happy hacking!
