Small tool to capture packets from wlan devices. After capturing, upload the "uncleaned" cap here (https://wpa-sec.stanev.org/?submit) to see if your ap or the client is vulnerable by using common wordlists. Convert the cap to hccapx and/or to WPA-PMKID-PBKDF2 hashline (16800) with hcxpcaptool (hcxtools) and check if wlan-key or plainmasterkey was transmitted unencrypted.

Stand-alone binary - designed to run on Raspberry Pi's with installed Arch Linux. It should work on other Linux systems (notebooks, desktops) and distributions, too.

Simply run:

make
make install (as super user)

or (with GPIO support - hardware mods required)

make GPIOSUPPORT=on
make GPIOSUPPORT=on install (as super user)

• Operatingsystem: Arch Linux (strict), Kernel >= 4.14 (strict). It should work on other Linux systems (notebooks, desktops) and distributions, too (no support for other distributions). Don't use Kernel 4.4 (rt2x00 driver regression)

• libpthread and pthread-dev installed

• Raspberry Pi: additionally libwiringpi and wiringpi dev installed (Raspberry Pi GPIO support)

• Chipset must be able to run in monitor mode (strict by: ip and iw). Recommended: RALINK chipset (good receiver sensitivity), rt2x00 driver (stable and fast)

• Raspberry Pi A, B, A+, B+ (Recommended: A+ = very low power consumption or B+), but notebooks and desktops could work, too.

• GPIO hardware mod recommended

• USB ID 0bda:8189 Realtek Semiconductor Corp. RTL8187B Wireless 802.11g 54Mbps Network Adapter

LED flashes 5 times if hcxdumptool successfully started

LED flashes every 5 seconds if everything is fine

Press push button at least > 5 seconds until LED turns on (LED turns on if hcxdumptool terminates)

Green ACT LED flashes 10 times

Raspberry Pi turned off and can be disconnected from power supply

Do not use hcxdumptool and hcxpioff together!

LED flashes every 10 seconds 2 times if hcxpioff successfully started

Press push button at least > 10 seconds until LED turns on (hcxpioff will shut down Raspberry Pi safely)

Green ACT LED flashes 10 times

Raspberry Pi turned off and can be disconnected from power supply

Do not use hcxdumptool or hcxpioff together!

You must use hcxdumptool only on networks you have permission to do this, because

• hcxdumptool is able to prevent complete wlan traffic

• hcxdumptool is able to capture PMKIDs from access points (only one single PMKID from an access point required)

• hcxdumptool is able to capture handshakes from not connected clients (only one single M2 from the client is required)

• hcxdumptool is able to capture handshakes from 5GHz clients on 2.4GHz (only one single M2 from the client is required)

• hcxdumptool is able to capture extended EAPOL (RADIUS, GSM-SIM, WPS)

• hcxdumptool is able to capture passwords from the wlan traffic

• hcxdumptool is able to capture plainmasterkeys from the wlan traffic

• hcxdumptool is able to capture usernames and identities from the wlan traffic
