A wifi network penetration test is an important aspect of any security audit project. Just like individuals, businesses face serious threats from their unsecured wifi network.

By nature, wifi is spread outside the walls of companiesIf your network is not secure, this allows a hacker to have access to your connection history, the emails you have exchanged, your passwords, etc. the confidentiality of your data. Indeed, an unsecured wifi puts all of the company's data at risk.

So businesses and individuals alike should include a WiFi penetration testing process as part of their regular security routine. In this article, we present a tools list which could be very useful during a wifi network intrusion test .


Aircrack-ng is a suite of software whose main use is to crack the WEP and WPA keys of wifi networks. Indeed, it can find the WEP key once enough encrypted packets have been captured.

The tool finds the WEP key using two main methods. The first is via the PTW approach (Pyshkin, Tews, Weinmann) which makes the attack much faster compared to other WEP cracking tools. The second method is the FMS / Korek method. This method incorporates various statistical attacks to discover the WEP key and uses them in combination with brute force.



Kismet is a free network detection software, a sniffer, and an intrusion detection system for 802.11 wireless network.

This tool works on 802.11 wireless networks and it is a different application to others as it does not send any detectable packets. This means that it is able, without itself sending a detectable packet, to detect the presence of both access points and wireless clients, and to associate them respectively.


It works under Linux, FreeBSD, and Mac OS X. Kismet can also work on Windows, but either with external engines, or with the only model of card for which there is a driver capable of doing monitor mode.


NetStumbler is software for Windows that makes it easy to discover 802.11b, 802.11a and 802.11g Wi-Fi networks.

In fact, this tool allowsidentify WiFi access points without protection to reconfigure them. It also makes it possible to ideally position an antenna or to ensure that the Wifi coverage of an area is adequate.



KisMAC is an excellent wireless network discovery tool for Mac OS X. It has many features that surpass NetStumbler.

This tool additionally offers some controversial security-related features. Concretely, in addition to detection, it offers cracking functions which are used to test the security of its wifi and to connect illegally to WiFi networks.

KisMAC is an excellent stumbler, a WiFi network detector with advanced features. Use to find a public WiFi network or to diagnose your own WiFi.

Fern WiFi Cracker

fern wifi cracker is a security audit application written in python and uses the Python Qt graphical library. To crack the protection of a wifi network, the application uses the Aircrak-ng and Reaper tools. Indeed, the program is able to decrypt and recover WEP/WPAWPS keys. It also allows to execute other attacks on wifi or ethernet networks.
