What is a Wi-Fi security test?

It is an assessment that checks the robustness of the corporate wireless network against real attacks: WPA2/WPA3 cracking, evil twin, deauthentication, rogue access points and traffic interception. It identifies the vulnerabilities of the wireless configuration.

Are corporate Wi-Fi networks vulnerable?

Often yes. Weak passwords, WPA2 without 802.1X, non-isolated guest networks, access points with outdated firmware and hidden SSIDs (which are not real protection) are common vulnerabilities in corporate wireless networks.

What are the risks of a compromised Wi-Fi network?

An attacker on the Wi-Fi network can intercept traffic, steal credentials, access internal resources, launch man-in-the-middle attacks and use the network as an entry point for lateral movement towards critical servers.

How often should Wi-Fi security be tested?

At least once a year and after every significant change to the wireless infrastructure (new access points, configuration changes, new sites). The test should cover the corporate network as well as guest and IoT networks.

What Wi-Fi Hacking Is.

It is a security analysis aimed at testing the vulnerability of Wi-Fi networks. Testers simulate attacks, such as traffic interception or unauthorized access, to identify weaknesses in configuration, encryption or access credentials.

Why Run a Wi-Fi Hacking Test.

A Wi-Fi test helps identify vulnerabilities in company networks before attackers can exploit them. It assesses the robustness of protection measures and leads to improvements that defend wireless networks from external or internal threats.

Benefits of Wi-Fi Hacking.

Wi-Fi tests improve the security of company networks by detecting weak points that could be exploited. They provide concrete data to implement effective protection measures, reducing the risk of unauthorized access and cyberattacks and strengthening the protection of sensitive data.

What do we detect?

Unprotected entry points in networks that could be exploited to gain unauthorized access.
Weaknesses in encryption protocols such as WEP, WPA and WPA2, which can be easily broken.
Lack of encryption, which allows interception of data transmitted in clear text over the Wi-Fi network.
The possibility of MITM attacks that can expose sensitive traffic between client and router.
Insecure network configurations, such as the use of WEP or a weak WPA password.

How does it work?

We use the deauth attack to force devices to disconnect from the network, useful to capture the 4-way handshake.
Capture of the 4-way handshake to try to crack the Wi-Fi network password through offline attacks.
We test the WPS protocol by trying to exploit vulnerabilities in the Wi-Fi setup feature.
Attackers try to intercept Wi-Fi traffic to collect sensitive data sent in clear text.

Wi-Fi Network Security Audit

Corporate wireless networks are an often underestimated attack vector. Unlike wired networks, which require physical access, a Wi-Fi network is reachable by anyone within range of the radio signal: company car parks, neighboring buildings, public areas. Fidem’s WiFi Hacking service tests the resilience of wireless networks with the same techniques used by real attackers.

Configuration Analysis

The first step is to analyze the configuration of access points and the wireless security policy: encryption protocol (WPA2-Enterprise, WPA3), authentication method (802.1X, PSK), wireless network segmentation, client isolation, SSID management and roaming policy. We identify the misconfigurations that can expose the network to compromise.

Wireless Penetration Testing

We carry out penetration tests specific to wireless networks: cracking WPA2-PSK keys, attacks on the 802.1X protocol (evil twin, relay attack), deauthentication for selective denial of service, rogue AP detection, segmentation tests (pivoting from the wireless VLAN to the core network), and wireless traffic analysis to intercept credentials and sensitive data.

Radio Exposure

We map how far the radio signal extends beyond the organization’s physical perimeter to assess the available attack area. A Wi-Fi signal that reaches the car park or the public street is an invitation to any attacker with a laptop and a directional antenna.

Rogue Device Detection

We identify unauthorized devices connected to the corporate wireless network: rogue access points installed by employees, unmanaged IoT devices, mobile hotspots that bypass security policies and any other device that could pose a risk.

What a Wi-Fi security test is

It is a simulated attack on the corporate wireless network, carried out with written authorization, to check whether someone outside, in the car park or the office next door, can get into the internal network. It is the perimeter almost nobody checks, because it cannot be seen: the Wi-Fi network extends beyond the building much more than people think.

What we check

Strength of authentication: WPA2/WPA3, quality of passphrases, enterprise configuration.
Guest network segregation: it is the most frequent defect, a guest network that reaches the production network.
Unauthorized access points: devices installed by someone in the company “because it was needed”, outside any control.
Impersonation attacks: a fake network with the same name, to see how many devices connect to it by themselves.
What can be reached once inside: the question that really matters; getting into the guest network is little, reaching the servers is another matter.

Is it legal?

Yes, on networks owned by the client and with written authorization that defines scope, timing and limits. Outside this, the same activity is a crime: we do not test third-party networks, nor shared networks without the consent of whoever manages them. In buildings with several companies, the authorization must be extended to whoever administers the infrastructure.

What it does NOT cover

The test concerns the wireless layer: it does not replace assessment of applications or of the Internet perimeter (vulnerability assessment and penetration testing), nor device protection (endpoint protection). Glossary.
