In order to attempt a WPS violation (again for testing purposes on our network), we will have to use the Reaver program, available within the Kali Linux distribution.ĭownload the Kali Linux ISO image and burn it to a DVD or USB stick in the latter case, we can use Unetbootin to create a Linux USB pen for use on any computer. So, in fact, WPA2 / AES has not been infringed, but it is possible to access a protected network with this protocol using the WPS vulnerability. Unfortunately this PIN is generated by a very weak algorithm (based on a part of the original modem password and/or its MAC Address): for hackers it was a breeze to create a “copy” of this algorithm and insert it at internal specific programs and apps, so you can “guess” most of the WPS PINs (and reflections of WPA passwords) in modems and modern routers. WPS allows you to quickly connect a new wireless device to the modem or router simply by pressing a special button: the connection of the devices is automatic and is based on the exchange of a PIN (generated by the modem or by the router). But hackers have “circumvented the problem” by focusing their efforts on the intrinsic vulnerabilities hidden in the WPS technology.

How to protect yourself from the WPS vulnerabilityĬurrently, the WPA2 protocol is quite secure, species if we choose a new secure password (at least 12 alphanumeric characters) and we use AES encryption (practically impossible to identify).

Obviously we recommend testing these methods only on the networks in our possession or only after asking the owner for explicit consent: we remind you that violating the networks of others without permission is a crime punishable under criminal and civil law, not to mention that nowadays the game is not worth the candle (given the continuous updates and the simple countermeasures that we can adopt to prevent this type of attack). If we want to test the goodness of the password chosen for our network and find out how to defend ourselves, in this guide we will show you the technique used for crack Wi-Fi network passwords with WPA / WPA2 protocol (on paper the safest). Wi-Fi networks are often targeted by highly skilled hackers, who use their knowledge to be able to get the network password on the most vulnerable devices or those that have technologies that simplify the life of users but make it easier to violate the security of our network.
