Wireless Penetration Test (VAPT)

Wireless VAPT for corporate wireless networks

Your network’s edge, tested where attackers begin

A wireless penetration test — also called wireless vulnerability assessment and penetration testing (VAPT) — places a CREST Registered Penetration Tester (CRT) within signal range of your premises. From inside the building, the tester assesses the wireless network for unauthorised access, weak encryption, and insecure wireless configurations that can increase risk exposure. Unlike a vulnerability assessment, wireless VAPT actively exploits confirmed weaknesses. Swarmnetics’ consultants in Singapore also hold the Offensive Security Certified Professional (OSCP) credential.

When proximity becomes an entry point

Because every signal tells a story—we decode it

In June 2024, the Australian Federal Police charged a man over alleged evil twin Wi-Fi networks used on commercial flights and at Australian airports to harvest credentials from nearby users. The attack depended on physical proximity, a stronger rogue signal, and users trusting a fake service that appeared legitimate. A wireless VAPT would have identified exposure to rogue access points before exploitation.

Organisations often need to validate wireless security alongside broader perimeter and monitoring controls through rigorous testing and annual penetration testing of relevant systems. For organisations across sectors, regular testing helps protect sensitive data, verify access controls, and support regulatory compliance against proximity-based attack paths that could give an attacker a foothold into internal network segments from within your premises.

Testing wireless exposure like an attacker

Seal the air, prove the value — outcomes you can use

Our consultants conduct a wireless pen test from following a testing process built around attacker behaviour rather than a checklist. Reconnaissance begins with airodump-ng to identify wireless networks, map each SSID, record the MAC address of every access point, and note the devices connected in range. We then capture WPA material and use Aircrack-ng and hashcat for dictionary attack and brute force testing against pre-shared keys.

Where automated scans reveal weaknesses, our team validates them manually to identify vulnerabilities, confirm the potential impact, and document identified vulnerabilities that affect overall security posture. We also force reassociation where appropriate, and test whether weak authentication, legacy SSIDs, or poor segmentation could let an attacker capture credentials or move further into the internal network. This shows what someone in physical proximity to your premises could realistically achieve, not just what a scanner can detect.

Yes, we are CREST accredited

Our core team is based in Singapore and consists of CREST certified penetration testers who are also Offensive Security Certified Professional (OSCP) certified. The team has delivered numerous penetration testing projects for customers in Singapore and other locations, from large multinational enterprises to small and medium business, and across various industries.

FAQ

Testing covers every corporate SSID accessible from within your building: authentication and encryption settings, pre-shared key strength, WPS implementation, and segmentation between wireless and wired segments.

Organisations with physical premises typically benefit from a black-box wireless VAPT because it mirrors attacker conditions. For multiple sites or more complex segmented environments, a grey-box approach can suit the scope better. Sharing SSID names and network topology with our team in advance reduces testing time without materially reducing coverage.

An attacker within signal range could crack pre-shared keys, harvest credentials through an evil twin access point, and move laterally into your wired corporate network. Wireless VAPT findings can include access to internal systems and data exfiltration without physical entry. Segmentation weaknesses remain among the most common high-severity findings.

A wireless penetration test from Swarmnetics produces a draft report for your review, followed by a final report upon acceptance. The report includes an executive summary, a detailed technical section with every finding listed by CVSS severity, proof-of-concept evidence demonstrating exploitability, and specific remediation guidance. After you have addressed the findings, we conduct a follow-up retest to confirm adequate remediation.

Any organisation that operates corporate wireless networks should consider a wireless penetration test. It is particularly relevant for organisations subject to regulatory, contractual, or industry security requirements, which requires regular penetration testing of network perimeter security and wireless network systems. A wireless penetration test is also recommended before launching new wireless network systems, after significant changes, and as part of an ongoing security assurance programme. Swarmnetics has conducted wireless penetration tests across all sectors since 2015.

The duration of a wireless penetration test depends on the scope — the number of wireless networks and SSIDs, their complexity, and whether a black-box or grey-box approach is used. A typical wireless security assessment takes three to five business days for the assessment phase, followed by an initial report within five business days for your review.

A wireless penetration test is often required for compliance with applicable regulatory, contractual, or industry security obligations where organisations must demonstrate that wireless network security controls are effective through regular testing, not just scanning. Swarmnetics recommends conducting a wireless penetration test at least annually, after significant changes, and before launching new wireless network systems into production.

Every wireless penetration test follows a three-phase process. In the planning phase, Swarmnetics agrees the scope, testing approach, and schedule with your team. In the assessment phase, our OSCP and CREST-certified consultants conduct manual wireless penetration testing covering authentication, encryption, and access controls to identify and actively exploit vulnerabilities, determining their real-world impact. In the reporting phase, we deliver a draft report for review and a final report with detailed remediation guidance for every finding.

All Swarmnetics penetration tests are conducted by our Singapore-based team of security consultants holding the Offensive Security Certified Professional (OSCP) and CREST Registered Penetration Tester (CRT) credentials. Swarmnetics has been delivering technical security assessments to organisations across Singapore since 2015 and acts as a trusted VAPT delivery partner to service and solution providers, supporting their customers across multiple sectors.

The security assessment report includes specific, actionable remediation guidance for every finding — not generic advice. For each vulnerability, we describe the fix, its priority based on CVSS severity, and any dependencies between remediation steps. Once your team has addressed the findings, Swarmnetics conducts a follow-up retest to verify that each vulnerability has been adequately remediated. The final report confirms closure and provides documented evidence of remediation.
