As a result it is difficult for state and federal agencies, water purveyors, and consultants to understand the effects of urbanization on the local surface-water, groundwater, and biologic resources or to critique ideas and opportunities for additional groundwater development.

Aircrack-ng is a whole suite of tools for Wireless Security Auditing. It can be used to monitor, test, crack or attack Wireless Security Protocols like WEP, WPA, WPA2. Aircrack-ng is command line based and is available for Windows and Mac OS and other Unix based Operating systems. Aircrack-ng suite contains a lot of tools used for various purposes but here we’ll only look at some important tools that are used more often in Wireless Security testing.Airmon-ngAirmon-ng is used to manage wireless card modes and to kill unnecessary processes while using aircrack-ng. To sniff a wireless connection, you need to change your wireless card from managed mode to monitor mode and airmon-ng is used for that purpose.Airodump-ngAirodump-ng is a wireless sniffer that can capture wireless data from one or more wireless Access Points. It is used to analyze nearby Access Points and to capture handshakes.Aireplay-ngAireplay-ng is used for replay attacks and as packet injector. It can be de-authenticate users from their APs to capture handshakes.Airdecap-ngAirdecap-ng is used to decrypt encrypted WEP, WPA/WPA2 wireless packets with known key.Aircrack-ngAircrack-ng is used to attack WPA/WEP wireless protocols in order to find the key.

InstallationAircrack-ng is easy to install in Ubuntu using APT. Just type the following command and this will install all tools available in Aircrack-ng suite. Ubuntu@ubuntu:$ sudo aireplay-ng -0 100 -a MACADD wlan0mon-a: Specify Access Points MAC for Aireplay-ng-0: Specify number of deauth packets to sendAfter a while, all devices will be disconnected from that Access Point, when they’ll try to reconnect, running airodump-ng will capture the handshake. It’ll appear at the top of running airodump-ng.Handshake is stored in ‘/tmp/’ directory, and contains encrypted password that can be brute forced offline using a dictionary. To crack the password, we’ll be using Aircrack-ng.
