Today we will continue to explore the application of Kali Linux in depth, this time we will focus on how to use Kali Linux for wireless network penetration testing. Wireless network penetration testing is an important step in evaluating wireless network security, and Kali Linux, as a professional penetration testing distribution, provides a wealth of tools to help you with this task.
1. Preparations
Before starting wireless network penetration testing, some preparations are necessary:
-
Wireless Adapter: Make sure your computer has a wireless adapter suitable for penetration testing to conduct wireless attacks and analysis in Kali Linux.
-
Learn Wireless Security: Learn the basics of wireless network security, including encryption protocols, vulnerabilities, and attack types.
2. Use Aircrack-ng for wireless penetration testing
Aircrack-ng is a commonly used wireless penetration testing tool in Kali Linux. It can help you perform operations such as password cracking, packet sniffing, and vulnerability exploitation. Let's use Aircrack-ng to crack WEP passwords as an example to introduce the steps of wireless penetration testing:
Step 1: Scan for wireless networks
Run the following command in a terminal to scan for nearby wireless networks using the Airodump-ng tool:
airodump-ng wlan0
This will display a list of nearby wireless networks, including their BSSID (the wireless router's MAC address) and signal strength.
Step 2: Select the target network
Select the target wireless network you want to attack and note its BSSID and channel.
Step 3: Start capturing packets
Run the following command to set up Airodump-ng to grab packets of the target network:
airodump-ng --bssid BSSID -c channel -w outputfile wlan0
Replace BSSIDwith the BSSID of the target network, channelwith the channel number of the target network, outputfilewith the filename where the packet is saved.
Step 4: Perform password cracking
Open another terminal window and run the following command to try to crack the WEP password using Aircrack-ng:
aircrack-ng -b BSSID -w wordlist outputfile.cap
Replace BSSIDwith the BSSID of the target network, wordlistwith the path to the password dictionary, and outputfile.capwith the previously captured packet file.
3. Precautions and Code of Ethics
When conducting wireless penetration testing, it is important to follow ethical guidelines and be legally licensed. Unauthorized wireless attacks can be a violation of the law with serious consequences.
