hcxdumptool

Small tool to capture packets from wlan devices. After capturing, upload the "uncleaned" pcapng here (https://wpa-sec.stanev.org/?submit) to see if your ACCESS POINT or the CLIENT is vulnerable by using common wordlists. Convert the pcapng file to WPA-PBKDF2-PMKID+EAPOL hashline (22000) with hcxpcapngtool (hcxtools) and check if PreSharedKey or PlainMasterKey was transmitted unencrypted.

Brief description

Stand-alone binaries - designed to run on Raspberry Pi's with installed Arch Linux. It may work on other Linux systems (notebooks, desktops) and distributions, too. Capture format pcapng is compatible to Wireshark and tshark.

Detailed description

Tool Description
hcxdumptool Tool to run several tests to determine if ACCESS POINTs or CLIENTs are vulnerable

Get source

git clone https://github.com/ZerBea/hcxdumptool.git
cd hcxdumptool

Solve dependencies (Debian based distributions: KALI, UBUNTU, ...)

You need to install missing dependencies before running make:

sudo apt-get install libcurl4-openssl-dev
sudo apt-get install libssl-dev

Compile

make
make install (as super user)

Or install via packet manager

Arch Linux

Arch Linux pacman -S hcxtools

Arch Linux ARM

Arch Linux ARM pacman -S hcxtools

Black Arch

Black Arch is an Arch Linux-based penetration testing distribution for penetration testers and security researchers
pacman -S hcxtools

Compile for Android

You need:

  • Android NDK installed in your system and in path variable

  • This repository cloned with all submodules (--recursive flag in git clone or git submodules update command run)

Just run ndk-build - built executables for some architectures should be created inside libs directory. Copy it to your phone and enjoy.

Requirements

  • Operatingsystem: Arch Linux (strict), Kernel >= 5.4 (strict). It may work on other Linux systems (notebooks, desktops) and distributions, too (no support for other distributions, no support for other operating systems).

  • Chipset must be able to run in monitor mode and driver must support monitor mode as well as full packet injection. Recommended: MEDIATEK (MT7601) or RALINK (RT2870, RT3070, RT5370) chipset

  • gcc 10 recommended (deprecated versions are not supported: https://gcc.gnu.org/)

  • libopenssl and openssl-dev installed

  • Raspberry Pi A, B, A+, B+, Zero (WH). (Recommended: Zero (WH) or A+, because of a very low power consumption), but notebooks and desktops may work, too.

  • GPIO hardware mod recommended (push button and LED).

Adapters

hcxdumptool need full (monitor mode and full packet injection running all packet types) and exclusive access to the adapter! Otherwise it will not start!

The driver must support monitor mode and full packet injection, as well as ioctl() system calls!

Virtual Netlink (libnl) interfaces are not supported!

Manufacturers do change chipsets without changing model numbers. Sometimes they add (v)ersion or (rev)vision.

Always verify the actual chipset with 'lsusb' and/or 'lspci'!

Due to a bug in xhci subsystem other devices may not work at the moment: https://bugzilla.kernel.org/show_bug.cgi?id=202541

No support for a third party driver which is not part of the official kernel (https://www.kernel.org/)

No support for a driver which doesn't support monitor and packet injection, native - if you need this features, do a request on www.kernel.org

Not recommended WiFi chipsets:

Intel PRO/Wireless

Broadcom

Realtek (mostly no monitor mode by kernel drivers)

Antennas

The best high frequency amplifier is a good antenna!

It is much better to achieve gain using a good antenna instead of increasing transmitter power.

Useful scripts

Script Description

Hardware mod - see docs gpiowait.odg (hcxdumptool)

LED flashes 5 times if hcxdumptool successfully started

LED flashes every 5 seconds if everything is fine and signals are received

LED flashes twice, if no signal received during the last past 5 seconds

Press push button at least > 5 seconds until LED turns on (also 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!

Hardware mod - see docs gpiowait.odg

LED flashes every 5 seconds 2 times if hcxpioff successfully started

Press push button at least > 5 seconds until LED turns on

Green ACT LED flashes 10 times

Raspberry Pi turned off safely and can be disconnected from power supply

Procedure

first run hcxdumptool -i interface --do_rcascan at least for 30 seconds

to determine that the driver support monitor mode and required ioctl() calls,

to determine that the driver support full packet injection,

to retrieve information about access points and

to determine which access points are in attack range.

Warning

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

  • hcxdumptool is able to prevent complete wlan traffic (depend on selected options)

  • hcxdumptool is able to capture PMKIDs from access points (only one single PMKID from an access point required) (use hcxpcapngtool to convert them to a format hashcat and/Or JtR understand)

  • hcxdumptool is able to capture handshakes from not connected clients (only one single M2 from the client is required) (use hcxpcapngtool to convert them to a format hashcat and/Or JtR understand)

  • hcxdumptool is able to capture handshakes from 5GHz clients on 2.4GHz (only one single M2 from the client is required) (use hcxpcapngtool to to a format hashcat and/Or JtR understand)

  • hcxdumptool is able to capture passwords from the wlan traffic (use hcxpcapngtool -E to save them to file, together with networknames)

  • hcxdumptool is able to request and capture extended EAPOL (RADIUS, GSM-SIM, WPS) (hcxpcapngtool will show you information about them)

  • hcxdumptool is able to capture identities from the wlan traffic (for example: request IMSI numbers from mobile phones - use hcxpcapngtool -I to save them to file)

  • hcxdumptool is able to capture usernames from the wlan traffic (for example: user name of a server authentication - use hcxpcapngtool -U to save them to file)

  • Do not use a logical interface and leave the physical interface in managed mode

  • Do not use hcxdumptool in combination with aircrack-ng, reaver, bully or other tools which take access to the interface

  • Stop all services which take access to the physical interface (NetworkManager, wpa_supplicant,...)

  • Do not use tools like macchanger, as they are useless, because hcxdumptool uses its own random mac address space

You can’t perform that action at this time.
