Preliminary information
Before getting into the tutorial, there are some important ones preliminary information which is my duty to provide you.
Let's start from a fundamental premise: find out the password of your wireless network it is an absolutely legal and risk-free practice. On the contrary, try to find out the password of other people's wireless networks represents a serious one privacy violation and can even be considered a crime (all, of course, if done without asking for the permesso al rightful owner and without having received explicit consent to the thing).
Based on the above, I invite you to put into practice the instructions contained in this guide only and exclusively to test the security of your wireless network or that of a person you know, who, however, must have been warned in advance and must have agreed to the thing.
It is absolutely not my intention to encourage illegitimate activities, therefore I take no responsibility for the use you may decide to make of the information in the tutorial.
However, contrary to what one might think, if the targeted connection is well protected, steal the password of a Wi-Fi connection it is not at all simple.
More precisely, if the network of your interest uses encryption WPA2-AES (which today constitutes one of the safest standards, unlike WEP, which is now considered obsolete and easily circumvented) and if the WPS is disabled (this is a function that allows you to press a special button on the modem / router to connect various devices to the wireless network generated by the device, without typing any access key; however convenient it may be, it has numerous security flaws ), a few clicks or taps are certainly not enough to succeed. That said, let's take action.
