WiFi pentesting is the process of assessing the security of a wireless network. It involves identifying vulnerabilities in the network and exploiting them to gain unauthorized access to the network and its resources.
WiFi pentesting is an important part of any cybersecurity strategy, as it can help to identify and fix security weaknesses before they can be exploited by malicious actors.
Steps of WiFi Pentesting
The following are the steps involved in WiFi pentesting:
Step 1: Reconnaissance
The reconnaissance phase involves gathering information about the wireless network that you want to pentest. There are a number of methods that can be used to gather this information, including:
- Open-source intelligence (OSINT): OSINT is the process of gathering information from publicly available sources, such as social media, search engines, and public records. OSINT can be used to identify the network name (SSID), the type of encryption used by the network, and the devices that are connected to the network.
- Social engineering: Social engineering is the process of manipulating people into revealing confidential information. Social engineering can be used to trick network administrators into revealing the network password or other security-sensitive information.
- Physical surveillance: Physical surveillance is the process of observing the target network environment to identify potential vulnerabilities. Physical surveillance can be used to identify the location of access points and other network devices, as well as the physical security of the network.
Once you have gathered as much information as possible about the wireless network, you can begin the scanning phase.
Step 2: Scanning
The scanning phase involves using specialized tools to identify vulnerabilities in the wireless network. Some of the most common WiFi scanning tools include:
- The Wireshark network packet analyzer is capable of capturing and analyzing network traffic. Wireshark can be used to identify vulnerabilities in the wireless network, such as weak encryption and misconfigured access points.
- Aircrack-ng: Aircrack-ng is a suite of tools that can be used to crack wireless encryption keys. Aircrack-ng can be used to gain unauthorized access to wireless networks that are protected with weak encryption.
Once you have identified vulnerabilities in the wireless network, you can begin the vulnerability assessment phase.
Step 3: Vulnerability assessment
The vulnerability assessment phase involves assessing the severity of the vulnerabilities that you have identified and the risk that they pose to the network. Some factors to consider when assessing the severity of a vulnerability include:
- The exploitability of the vulnerability: How easy is it to exploit the vulnerability?
- The impact of the vulnerability: What is the impact to the network if the vulnerability is exploited?
- The likelihood of the vulnerability being exploited: How likely is it that the vulnerability will be exploited by malicious actors?
Once you have assessed the severity of the vulnerabilities, you can begin the exploitation phase.
Step 4: Exploitation
The exploitation phase involves exploiting the vulnerabilities that you have identified to gain unauthorized access to the wireless network. The specific steps involved in exploiting a vulnerability will vary depending on the type of vulnerability.
Once you have gained unauthorized access to the wireless network, you can begin the reporting phase.
Step 5: Reporting
The reporting phase involves generating a report that documents your findings and recommendations. The report should include a description of the vulnerabilities that you identified, the steps you took to exploit the vulnerabilities, and the impact of the vulnerabilities on the network.
The report should also include recommendations for fixing the vulnerabilities that you identified.
WiFi pentesting is an important part of any cybersecurity strategy. By following the steps and approach outlined in this blog post, you can help to identify and fix security weaknesses in your wireless network before they can be exploited by malicious actors.
Here are some additional tips for WiFi pentesting:
- Use a variety of tools and techniques. There are many different tools and techniques that can be used for WiFi pentesting. Using a variety of tools and techniques will help you to identify a wider range of vulnerabilities.
- Keep up to date with the latest vulnerabilities. New vulnerabilities are discovered all the time. It is important to keep up to date with the latest vulnerabilities so that you can test for them.
- Be patient. WiFi pentesting can be time-consuming. It is important to be patient and to take the time to thoroughly test the network.
