Wireless Hacking

This is just a quick post to provide the presentation I gave tonight at PwnSchool.  If you’d like to review it you can download it here.  Thanks!

Topics covered:

  • Introduction to Radio Frequency
  • Wireless  Hacking (WEP and WPA2)
  • RFID Hacking (HID Prox and MIFARE)
  • Bluetooth Hacking (Bluelog/bluesnarfer/Wireshark/etc)

WPA Handshake Stripping

Many thanks to INIT_SIX for also pointing out a quick way to reduce the size of your WPA handshake captures using pyrit:

pyrit -r /path/to/capture.cap -o /path/to/handshake-only-output.cap strip

Add the “-e” or “-b” switches to filter down to just a single AP by ESSID or BSSID respectively:

pyrit -r capture.cap -o output.cap -b "99:88:77:66:55:44" strip

That’s it! Good hunting!

Wireless Attack: WPA

The following is a quick-hit list of commands for attacking a WPA wireless network. It assumes you are using a 2016 variant of Kali linux with the aircrack-ng suite installed and a wireless network card that can be placed into monitor mode (which should be about 100% of them). It also assumes that there is a WPA network with an associated client that is transmitting, and that you are running as a user with sufficient permissions to execute each of these commands.

For the sake of this tutorial the AP will be assumed to have a MAC address of “99:88:77:66:55:44” and the client will be assumed to have a MAC address of “00:11:22:33:44:55”. The wireless network card we will use will be assumed to be “wlan0”.
