Cracking the password for WPA2 networks has been roughly the same for many years, but a new attack requires less interaction and information than previous techniques and has the added advantage of being able to target access points with no one connected. This new attack against the PMKID uses Hashcat to crack WPA passwords and allows hackers to find networks with weak passwords more easily.
The Old Way to Crack WPA2 Passwords The old way of cracking WPA2 has been along quite some time and involves momentarily from the access point we want to try to crack. This has two downsides which are important for Wi-Fi hackers to understand. The first downside is the requirement that someone is connected to the network to attack it. The network password might be weak and very easy to break, but without a device connected to briefly kick off, there is no opportunity to capture a handshake, thus no chance to try cracking it.

Don't Miss: The second downside of this tactic is that it's noisy and legally troubling in that it forces you to send packets that deliberately disconnect an authorized user for a service they are paying to use. This kind of unauthorized interference is technically a denial-of-service attack and, if sustained, is equivalent to jamming a network. This can get you into trouble and is easily detectable by some of our previous guides.
A New Method of Password Cracking Rather than relying on intercepting two-way communications between Wi-Fi devices to try cracking the password, an attacker can communicate directly with a vulnerable access point using the new method. 4, 2018, a detailed a new technique leveraging an attack against the RSN IE (Robust Security Network Information Element) of a single EAPOL frame to capture the needed information to attempt a brute-force attack. Similar to the previous attacks against WPA, the attacker must be in proximity to the network they wish to attack. The objective will be to use a to capture the information needed from the network to try brute-forcing the password. Rather than using Aireplay-ng or Aircrack-ng, we'll be using a new wireless attack tool to do this. Don't Miss: Using Hcxtools & Hashcat Hcxdumptool and hcxpcaptool are tools written for Wi-Fi auditing and penetration testing, and they allow us to interact with nearby Wi-Fi networks to capture WPA handshakes and PMKID hashes.
It works similar to in that it requires minimal arguments to start an attack from the command line, can be run against either specific targets or targets of convenience, and can be executed easily over SSH on a or another device without a screen. Once the PMKID is captured, the next step is to load the hash into and attempt to crack the password. This is where hcxtools differs from Besside-ng, in that a conversion step is required in order to prepare the file for Hashcat to use. We'll use hcxpcaptool to convert our PCAPNG file into one Hashcat can work with, leaving only the step of selecting a strong list of passwords for your brute-forcing attempts. Don't Miss: It's worth mentioning that not every network is vulnerable to this attack.
Because this is an optional field added by some manufacturers, you should not expect universal success with this technique. Whether you are able to capture the PMKID depends on if the manufacturer of the access point did you the favor of including an element that includes it, and whether you can crack the captured PMKID depends on if the underlying password is contained in your brute-force password list. If either condition is not met, this attack will fail.
What You'll Need To try this attack, you'll need to be running and have access to a that supports monitor mode and packet injection. We have several guides about selecting a compatible wireless network adapter below. Don't Miss: Aside from a, make sure that you've fully updated and upgraded your system.
If you don't, some packages can be out of date and cause issues while capturing. Recommended: Step 1: Install Hxctools & Hashcat First, we'll install the tools we need. To download, type the following into a terminal window. Git clone cd hcxdumptool make make install When this finishes installing, we'll move onto installing hxctools.
To do this, open a terminal window and paste the following line by line. If you get an error, try typing sudo before the command. Cd git clone cd hcxtools make make install Finally, we'll need to install Hashcat. This should be easy, as it's included in the Kali Linux repo by default. Simply type the following to install the latest version of Hashcat. Apt install hashcat With this complete, we can move on to setting up the wireless network adapter.
Step 2: Prepare the Wireless Network Adapter After plugging in your Kali-compatible wireless network adapter, you can find the name by typing or ip a. Typically, it will be named something like wlan0. The first step will be to put the card into wireless monitor mode, allowing us to listen in on Wi-Fi traffic in the immediate area.
To do this, type the following command into a terminal window, substituting the name of your wireless network adapter for wlan0. Airmon-ng start wlan0 Found 3 processes that could cause trouble Kill them using 'airmon-ng check kill' before putting the card in monitor mode, they will interfere by changing channels and sometimes putting the interface back in managed mode PID Name 555 NetworkManager 611 wpasupplicant 6636 dhclient PHY Interface Driver Chipset phy0 wlan0 ath9k Qualcomm Atheros QCA9565 / AR9565 Wireless Network Adapter (rev 01) (mac80211 monitor mode vif enabled for phy0wlan0 on phy0wlan0mon) (mac80211 station mode vif disabled for phy0wlan0) phy1 wlan1 ath9khtc Atheros Communications, Inc. AR9271 802.11n Now, your wireless network adapter should have a name like 'wlan0mon' and be in monitor mode. You can confirm this by running ifconfig again. Step 3: Use Hxcdump to Capture PMKIDs from Local Networks Now we are ready to capture the PMKIDs of devices we want to try attacking.
With our wireless network adapter in monitor mode as 'wlan1mon,' we'll execute the following command to begin the attack. Hcxdumptool -i wlan1mon -o galleria.pcapng -enablestatus=1 Breaking this down, -i tells the program which interface we are using, in this case, wlan1mon. The file name we'll be saving the results to can be specified with the -o flag argument.
The channel we want to scan on can be indicated with the -c flag followed by the number of the channel to scan. In our command above, we're using wlan1mon to save captured PMKIDs to a file called 'galleria.pcapng.' While you can specify another status value, I haven't had success capturing with any value except 1.
Quite unrelated, instead of using brute force, I suggest going to fish 'almost' literally for WPA passphrase. You need quite a bit of luck.
Using a tool like, one can sometimes instead of SSID, get a WPA passphrase in clear. The explanation is that a novice (android?) user inputted the passphrase in the SSID field when trying to connect to an AP. (If you go to 'add a network' in wifi settings instead of taping on the SSID right away) Since then the phone is sending probe requests with the passphrase in clear as the supposedly SSID.
One problem is that it is rather random and rely on user error. You only get the passphrase but as the user fails to complete the connection to the AP, the SSID is never seen in the probe request. So you don't know the SSID associated with the pasphrase you just grabbed. So if you get the passphrase you are looking for with this method, go and play the lottery right away. You are a very lucky (wo)man. Hi, hashcat was working fine and then I pressed 'q' to quit while it was running.
