A wifi network penetration test is an important aspect of any security audit project. Just like individuals, businesses face serious threats from their unsecured Wi-Fi network.
By nature, wifi is spread outside the walls of companies. If your network is not secure, this allows a hacker to have access to your connection history, the emails you have exchanged, your passwords, etc., which constitutes serious harm for the confidentiality of your data. Indeed, unsecured Wi-Fi puts all company data at risk.
So businesses and individuals alike should include a WiFi penetration testing process in their regular security procedure. In this article, we present to you a tools list which could be very useful during a intrusion test of a wifi network .
Aircrack-ng
Aircrack-ng is a suite of software whose main use is to crack WEP and WPA keys from wifi networks. This is because 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 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
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 from others because it does not send any detectable packets. This means that it is capable, without sending a detectable packet itself, of detecting both the presence of access points and wireless clients, and associating them respectively.
It runs on Linux, FreeBSD, and Mac OS X. Kismet can also run on Windows, but either with external engines, or with the only card model for which there is a driver capable of monitor mode.
netstumbler
NetStumbler is software for Windows which facilitates the detection of 802.11b, 802.11a and 802.11g Wi-Fi networks.
In fact, this tool allows you toidentify WiFi access points without protection to reconfigure them. It also allows you to ideally position an antenna or to ensure that WiFi coverage in an area is adequate.
KisMAC
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 graphics library. To break the protection of a wifi network, the application uses the Aircrak-ng and Reaper tools. Indeed, the program is capable of decrypting and recovering WEP/WPAWPS keys. It also allows other attacks to be carried out on WiFi or Ethernet networks.
