wpa2own – Use hashcat to crack WPA2 PSK (Pre-Shared Key) passwords!

Crack WPA The goal of this project is to automate the process of capturing packets on a WPA2 protected wireless network, and crack their PSK (pre-shared keys). We know that WPA3 is coming, but most didn’t know that WPA2 was as susceptible to being broken as it is with this recently released Hashcat method.

Requirements

Hardware

  • a 64 bit Linux system with a network card that supports montior mode – see Gotchas
  • a 64 bit Linux system with a GPU (graphics processing unit) for running Hashcat against the pcap – again, see Gotchas. In this example we’re assuming this is a separate machine, but in the case that you have both on one system, we could rework things to account for that.

System utilities

  • bash
  • curl
  • git
  • make
  • rsync
  • sudo

Packages needed to build hcxtools

  • libopenssl and openssl-dev installed
  • librt and librt-dev installed (should be installed by default)
  • zlib and zlib-dev installed (for gzip compressed cap/pcap/pcapng files)
  • libcurl and curl-dev installed (used by whoismac and wlancap2wpasec)
  • libpthread and pthread-dev installed (used by hcxhashcattool)

EXAMPLE: to install all software requirements in Debian Linux, Ubuntu Linux, or Kali Linux:

sudo apt-get -y install libcurl4-openssl-dev libssl-dev zlib1g-dev libpcap-dev libgmp3-dev

TODO: include package list for other Linux distros. LMK if you figure any out!

Tools that the script will download and build

  • hcxdumptool (v4.2.0+)
  • hcxtools (v4.2.0+)
  • hashcat (v4.2.0+)

Gotchas

  1. You need a networking card that supports monitor mode under Linux, from online posts I’ve seen the following NICs listed:
Supported adapters (strict)

USB ID 148f:7601 Ralink Technology, Corp. MT7601U Wireless Adapter
USB ID 148f:3070 Ralink Technology, Corp. RT2870/RT3070 Wireless Adapter
USB ID 148f:5370 Ralink Technology, Corp. RT5370 Wireless Adapter
USB ID 0bda:8187 Realtek Semiconductor Corp. RTL8187 Wireless Adapter
USB ID 0bda:8189 Realtek Semiconductor Corp. RTL8187B Wireless 802.11g 54Mbps Network Adapter

For development and testing, I used the Ralink RT5370 USB wireless plugged into my Mac Book Air (6,1) laptop. The output from lusb is:

$ lsusb | grep Ralink
Bus 001 Device 039: ID 148f:5370 Ralink Technology, Corp. RT5370 Wireless Adapter
  1. The old hashcat-legacy uses the CPU to try and crack hashes, but that code is over 3 years old, and is going to be far too slow to crack what we’re capturing here. I might provide it as an option, but it’s really more of a POC that you could used in canned environments with very simple passwords. To really get the ball rolling you can should use hashcat with the OpenCL headers (we pull those down as part of the build), and that requires a system with a compatible GPU.

TODO: give examples of how this works, with specfic drivers

Usage

After resolving the requirements and understanding the gotchas:

./wpa2own

NOTICE (8/14/2018) currently, once the scan is complete, your output file is saved in the out/ dir, ready to run against hashcat on a system with GPU processors. I’m working to get this bit automated so it will scp the file to a GPU enabled rig, run it there and give you the results. This is a WIP, working to have complete by next week!
