 In this tutorial we are going to show how you can get a WiFi password from any visible APs around you. We will use the Aircrack-ng tool and, because we are going to use [[http://www.kali.org|Kali Linux]] distribution, we haven't given any detail about the installation of this tool. In Kali, every tool wee need is already installed.

   * Try to discover the password using a dictionary attack
-By the moment we will try to discover the WiFi password by dictionary attack. To do that, first, we need a dictionary. Because we are using Kali we can found some dictionaries in the ''/usr/share/wordlists''. For example, in this case, we will use ''rockyou.txt.gz''. You can found other dictionary in some links in [[resources|Resources]]

 As you can see in the example above, it is not very difficult to perform an attack to get a WiFi password if the connection is not properly configured. We must notice the following aspects:
-  * Only select WPA/WPA2-PSK encryption methods
+  * You must select only WPA/WPA2-PSK encryption methods. In this way you can prevent that someone crack your WiFi password
-  * Change default password for a real stronger password. You must use letters, numbers, capital letters and special characters (like !, ., ?). You can check if your password is strong enough in some websites like [[https://password.kaspersky.com|Kaspersky Secure Password Check]]

-  * You also can change the SSID of your Wifi connection. Notice that some companies put similar names to all WiFi routers they provide. In this case, it is easy to know which type of router you have and to look for, for example, an specific vulnerability on it.

An attacker can obtain passwords from an specific password generator that generates them following the same seed that the company of your router.
