We’ve all been locked out of our Wi-Fi networks before. Maybe you have a new router installed and the default password sticker is missing. Or, you changed the password last night but you just can’t remember it anymore (Yes, that has actually happened to a lot of people). Whatever it may be, one thing is for sure; you really need to use your Wi-Fi and we’re going to show you exactly how to crack WiFi password in a few easy steps. However, please note that we DO NOT advise, encourage or endorse hacking of someone else’s Wi-Fi network. Therefore, let’s just be civil and nice, shall we?
What is The New Security Exploit?
We’re going to learn how to crack WiFi password using this new security exploit found by a security consultant/researcher. He was analyzing the WPA 3 security standard and found a major flaw in the WPA/WPA2 wireless network protocol. Since most modern home routers use the WPA/WPA2 with PKMID (Pairwise Master Key Identifier), this led him to learn how to crack wifi password easily. WPA2-PSK is Wi-Fi protected access 2-Preshared key and it is a method of protecting your Wi-Fi network using pre-shared key authentication. Moreover, this is used in most home networks and thus is now vulnerable.
How to Crack WiFi Password with WPA/WPA2-PSK?
The newly discovered flaw in the WPA2-PSK protocol allows an attacker to gain access to the pre-shared key login passwords of your Wi-Fi network. This would easily open the gate to the wireless network and thus, allow access to the network. Therefore, this would let anyone know how to crack Wi-Fi password of a targeted network.
All previous hacking methods required a long wait for someone to log into the wireless network and retrieve a 4-way authentication handshake of another authentication protocol called EAPOL. However, with this new exploit, you no longer need another user. It is rather performed on the Robust Security Network Information Element (RSN IE).
Moreover, the Robust Security Network communicates over 802.11 wireless networks and uses PKMID as the key and we all know that PKMID has our targeted exploit.
Let’s Crack Wifi Password using PMKID
Now, to learn how to crack WiFi password using the exploits mentioned above, follow these steps:
- You can use a tool like hcxdumptool in order to retrieve the PMKID from the wireless network and then dump the retrieved frame into a file.
$ ./hcxdumptool -o test.pcapng -i wlp39s0f3u4u5 --enable_status
- Now, use hcxpcaptool tool to convert the output of the frame (in pcapng format) into a hash format that is compatible with a password cracking tool like Hashcat.
$ ./hcxpcaptool -z test.16800 test.pcapng
- Simply download a password cracking tool like Hashcat to retrieve the WPA PSK password and you’re pretty much done.
$ ./hashcat -m 16800 test.16800 -a 3 -w 3 '?l?l?l?l?l?lt!'
And there it is, that would let you find the password of the targeted wireless network. However, cracking this may take some time depending on how much characters it has, how complex the characters are and other factors that may affect complexity. Learning how to crack WiFi password wasn’t that hard, was it?
This Wi-Fi cracking method only works against the 802.11i/p/q/r networks that have roaming functions enabled. Therefore, it will work in most modern Wi-Fi routers. Now you know how to crack a WiFi password and you can have a sigh of relief. You may now go to your router settings and change the Wi-Fi password to one that you can actually remember. However, that is a story for another day. Enjoy access to your Wi-Fi!
