The following would be displayed in the terminal if the command ran successfully: The file path chosen is /root/Desktop/hack in the above command, so the packets captured by airdump-ng will be written to the file named hack in the Desktop or the /root/Desktop directory. The network interface, in the example shown, is wlan0mon. w is the directory where the captured data is written to, which, in this case, is '/root/Desktop/hack' but can be changed to an arbitrary location. c: is the channel of the target Wi-Fi which in this case is 10 (see in the previous screenshot for channel number) bssid: it has been indicated with a red mark in the screenshot.
Įxplanation of the flags (or options) used in the command: The final command in this step will be airodump-ng -c channel -bssid -w wlan0mon. Add some more parameters to the airodump-ng command.Note: Do not close this terminal because it will be used to know whether the WPA handshake has been captured or not. It will also gather data from the wireless packets. This command captures the network packets. Use the command airodump-ng wlan0mon, as shown below, to display all the access points in the computer's proximity, including the clients connected to that access point.Note: Use the wireless interface, which is indicated by the red mark in the above screenshot. Using the interface in the terminal, use wlan0mon. If there are any such errors, the command airmon-ng check kill should be used to kill the process as shown below.Įnable the monitor mode in the Wi-Fi card (wlan0) by using the command airmon-ng start wlan0 (interface of wireless card). If connected to an external wireless card, it may be wlan1 or even wlan2.įor certain wireless cards, some error messages may be shown (for example, enable monitor mode error). In this case, *wlan0* is the name of the wireless adapter, which may vary depending on the system configuration. In the terminal, use the iwconfig to determine the name of the wireless adapter, as there may be multiple wireless network interfaces on the system.Steps to crack Wi-Fi WPA/WPA2 passwords using Aircrack-ng The goal here is to capture the WPA/WPA2 authentication handshake by sending de-authentication packets to crack the pre-shared key using the aircrack-ng tool. It is worthwhile to mention that if no one is connected to the target Wi-Fi network, it won't be possible to crack it, as it won't be possible to perform a WPA/WPA2 handshake without a client being connected to the network. Then it needs to be determined whether the victim is connected to the target Wi-Fi network. Wi-Fi works by transmitting network packets, which can be captured and dumped using airodump-ng, part of aircrack-ng.
HOW TO CRACK WIFI PASSWORDS USING KALI LINUX HOW TO
To understand how to crack Wi-Fi, one needs to know how Wi-Fi works. To crack the Wi-Fi network password, the PC/computer should have an external wireless card capable of running a monitor or injection mode.Kali Linux can be A) installed or B) used in the Live version through a Bootable version or C) installed on a VM using VMWare or Virtual Box.In this post, Aircrack-ng will be used to crack a password-protected WPA/WPA2 Wi-Fi network.
It is capable of monitoring (capturing packets), attacking, and cracking Wi-Fi networks. Aircrack-ng is a set of tools in Kali Linux that can be used to assess Wi-Fi network security.
