How To Perform A Wireless Penetration Test
What is a wireless penetration test?
Wireless penetration testing identifies and investigates connections between all devices connected to your organization’s wireless network. These devices include laptops, tablets, smartphones, and other Internet of Things (IoT) devices. Penetration testing must be within range of the wireless signal for access, so
wireless penetration testing is typically performed on the customer’s website.
official penetration testing should focus primarily on the most easily exploited vulnerabilities.
This is often referred to as “finding hanging fruit” because these identified vulnerabilities are the highest risk and easiest to exploit. For
- WiFi networks, these vulnerabilities are most commonly found on WiFi access points.
- A common reason for this is poor network access control and lack of MAC filtering.
- If these security controls are not used to effectively increase the security of your WiFi network, malicious hackers will gain great benefits to your organization and use various techniques and WiFi hacking tools to your network. You can get unauthorized access.
Steps to Perform Wireless Penetration Test
As mentioned above, we will focus on the methods and procedures for testing WiFi networks and provide examples of specific attacks and tools to achieve your goals.
Wireless Penetration Steps
Below is a list of steps that can be categorized into different areas of penetration testing.
1. Wireless Reconnaissance
The first step in the penetration testing process is the information-gathering phase before jumping directly into the hacking process.
Due to the nature of Wi-Fi, the information we collect is done via wardriving. This is an intelligence-gathering method that involves driving an area to spy on Wi-Fi signals.
This requires the following equipment:
Car or other means of transportation. Laptop and Wi-Fi antenna. Wireless network adapter. Packet capture and analysis software.
2. Identify the Wireless Network
The next step in the Wi-Fi Penetration Test is to scan or identify the wireless network.
Before this phase, the wireless card must be in “monitoring” mode, packet capture enabled, and the wireless interface configured. Specify the
WiFi interface After the
WiFi card starts listening for WiFi traffic, you can start scanning with airodump to scan for traffic on different channels. Scanning with
airodump An important step to reduce the workload during the
the scanning process is to have airodump capture traffic only on specific channels.
3. Vulnerability Investigation
After a scan detects a wireless access point, the next phase of testing will focus on identifying the access point’s vulnerabilities. The most common vulnerability is in the 4-way handshake process. In this process, the encrypted key is exchanged between the wireless access point and the authentication client.
Use the Airplay NG suite tool to implement the exploit effort in the following ways:
Deauthorize a legitimate client.
Captures the first 4-way handshake when a legitimate client reconnects.
Perform an offline dictionary attack to decrypt the captured key.
We have already started capturing traffic for a specific channel, so let’s move on to the next step.
