Secure Your Wireless Networks Against Modern Threats
Wireless networks remain one of the most vulnerable entry points into corporate infrastructure. Our WiFi Penetration Testing service identifies security weaknesses in your wireless networks before attackers can exploit them.
Aardwolf Security’s CREST-certified team uses advanced manual testing techniques and automated tools to simulate real-world wireless attacks. We assess your entire wireless infrastructure for vulnerabilities and provide actionable remediation advice.
What Is WiFi Penetration Testing?
WiFi penetration testing is a proactive security assessment that evaluates wireless network security. Our ethical hackers simulate attack techniques used by malicious actors to identify vulnerabilities in your wireless infrastructure.
The assessment examines authentication mechanisms, encryption protocols, access point configurations, and network segmentation. We also test for signal leakage, rogue access points, and client-side vulnerabilities.
Unlike automated scanning, our manual testing approach uncovers complex security issues that tools alone might miss. We analyse how multiple vulnerabilities could be chained together in sophisticated attack scenarios.
Our testing goes beyond simple compliance checking to provide a real-world assessment of your wireless security posture.
Why Your Organisation Needs WiFi Penetration Testing
Wireless networks create unique security challenges compared to wired infrastructure. Modern attackers can target WiFi networks from outside your physical premises without needing direct access.
Many organisations implement robust security for their internal networks but neglect wireless security. This oversight creates an attractive entry point for attackers seeking access to sensitive corporate data.
Recent security research has revealed critical vulnerabilities in WPA2 and even newer WPA3 protocols. These vulnerabilities can allow attackers to decrypt traffic, hijack connections, or gain unauthorised network access.
Regular penetration testing of your wireless infrastructure helps maintain compliance with regulatory standards. Testing supports frameworks like ISO 27001, PCI DSS, and GDPR by demonstrating due diligence in securing personal data.
Most importantly, WiFi penetration testing provides peace of mind that your wireless networks can withstand attack attempts. Identifying and addressing vulnerabilities proactively prevents potential breaches and protects your organisation’s reputation.
Our WiFi Penetration Testing Methodology
Our comprehensive WiFi penetration testing methodology follows industry-standard frameworks while incorporating our proprietary techniques. We align our approach with OSSTMM and SANS methodologies to ensure thorough coverage.
Information Gathering
The assessment begins with passive reconnaissance to identify all wireless networks associated with your organisation. We collect information about:
- SSID broadcasts and naming conventions
- Signal strength and coverage areas
- Authentication methods in use
- Encryption protocols implemented
- Hardware vendors and models
This passive phase helps map your wireless footprint without alerting defensive systems.
Vulnerability Assessment
Once we understand your wireless environment, we conduct systematic testing for common security issues:
- WEP/WPA/WPA2/WPA3 configuration weaknesses
- Pre-shared key strength analysis
- Management interface security
- Default credentials and hardening gaps
- Outdated firmware vulnerabilities
- Misconfigured access points
We use specialised tools and manual techniques to identify potential security flaws.
Exploitation Phase
With your explicit permission, we safely exploit discovered vulnerabilities to validate their severity. This may include:
- Capturing and cracking authentication handshakes
- Conducting evil twin attacks
- Testing client isolation effectiveness
- Attempting network pivoting between segments
- Evaluating post-authentication vulnerabilities
- Bypassing captive portals
All exploitation activities follow strict guidelines to prevent service disruption.
Signal Leakage Assessment
We evaluate how far your wireless signals propagate beyond intended boundaries. Excessive signal leakage can enable attacks from car parks, public areas, or neighbouring buildings.
Our team uses specialised equipment to map signal strength at your perimeter. We identify areas where signals extend beyond secure zones and recommend adjustments to access point placement or power settings.
Rogue Access Point Detection
Unauthorised access points pose significant security risks. We conduct a thorough sweep of your premises to identify:
- Unauthorised employee-deployed access points
- Malicious rogue access points planted by attackers
- Misconfigured legitimate access points
- Forgotten or abandoned wireless devices
Each identified device undergoes security evaluation to determine its risk level.
Comprehensive Reporting
Our detailed reports provide clear, actionable information about discovered vulnerabilities. Each report includes:
- Executive summary for non-technical stakeholders
- Detailed technical findings with risk scores
- Step-by-step exploitation proof-of-concept
- Business impact analysis for each vulnerability
- Practical remediation recommendations
- Comparative analysis against industry benchmarks
We conclude with a debrief session to explain findings and answer questions about remediation steps.
Common WiFi Security Vulnerabilities We Identify
Weak Authentication Mechanisms
Many organisations rely on simple pre-shared keys for wireless authentication. We test password strength and identify implementations vulnerable to:
- Dictionary and brute force attacks
- WPA/WPA2 handshake capture and offline cracking
- WPS PIN vulnerabilities
- Key reinstallation attacks (KRACK)
- Downgrade attacks forcing weaker protocols
We recommend stronger authentication methods based on your organisation’s needs.
Inadequate Network Segmentation
Proper network segmentation prevents lateral movement between wireless networks. Our testing identifies:
- Missing VLAN implementation between networks
- Firewall bypass vulnerabilities
- Routing misconfiguration allowing cross-network access
- Inadequate separation between guest and corporate networks
- Unauthenticated access to sensitive resources
Proper segmentation creates essential security boundaries between network zones.
Client Isolation Failures
Guest networks should prevent communication between connected devices. We test isolation mechanisms to ensure clients cannot:
- Scan other connected devices
- Access shared resources from other clients
- Intercept traffic from neighbouring devices
- Conduct ARP poisoning or MITM attacks
- Exploit vulnerabilities in other client devices
Failed isolation creates attack vectors between wireless clients.
Insecure Access Point Configuration
Default and misconfigured access points create unnecessary risks. We identify:
- Unpatched firmware with known vulnerabilities
- Accessible management interfaces with weak credentials
- Unnecessary services enabled
- Insecure protocols allowed (TFTP, Telnet)
- Missing security hardening measures
These configuration issues can provide attackers with control over your wireless infrastructure.
Case Study: Exploiting WPA2 Enterprise Vulnerabilities
The following scenario demonstrates how we uncovered critical vulnerabilities in a financial services client’s wireless infrastructure:
- During initial scanning, we identified their corporate network used WPA2 Enterprise with PEAP authentication
- We deployed a rogue access point mimicking their legitimate SSID
- When employees’ devices attempted to connect, we observed they had disabled certificate validation
- This allowed our rogue access point to capture authentication credentials
- Using captured credentials, we gained access to the internal network
- Further testing revealed no network segmentation between wireless and sensitive servers
- We demonstrated potential access to financial data through this wireless vulnerability chain
This finding led to immediate implementation of certificate validation enforcement and proper network segmentation.
