Wi-Fi Pentesting

Wireless technology remains a weak spot in many infrastructures. A Wi-Fi penetration test, or pentest, will reveal wireless weak points, exploit the vulnerabilities and provide clear advice on how to mitigate the risks to an acceptable level.

WiFi and other wireless technologies such as Bluetooth, 2G/3G/4G and Zigbee or WirelessHart in the industrial domain, remain a weak point in many infrastructures. Some wireless technologies can be easily disrupted or taken over, even remotely. Secura has developed specific testing protocols for such technologies. Combined with physical access testing or site surveys, knowing the susceptibility of your wireless infrastructure to attack is an important aspect of becoming more resilient. Secura will investigate on-site if the Wi-Fi (wireless) networks are adequately secured. For this, Secura will use laptops with IEEE 802.11a/b/g/n/ac/ax-network adapters and test access points.


How We Test

Secura will intercept and analyze traffic of available wireless networks. In this phase, it will be determined if the traffic is encrypted and how it is encrypted. If it is unencrypted, Secura will analyze the content of the traffic to determine if it belongs to the customer’s network and if it contains sensitive and/or useful information.

Only Wi-Fi networks that are positively attributable to our customers are subjected to the tests.

After a Wi-Fi security test, Secura will be able to answer the following questions:

  • Which Wi-Fi networks are available?
  • What security measures are in place and are they sufficient?
  • Is it possible to access internal systems through a public/guest Wi-Fi network?
  • Is it possible to access other guests systems through the public/guest Wi-Fi network?
  • Can traffic be intercepted and decrypted?

When we encounter networks that should be segregated, we will investigate whether they are configured correctly to prevent connections between the networks. Secura will identify vulnerabilities on the access points and attempt to exploit these.

A typical example would be a situation where Secura investigates possibilities of breaking out of a guest network into the office automation network, of if guests can attack each other’s system.

When network traffic is encrypted, Secura will attempt to crack the implemented security technology and recover the Wi-Fi key. Such an attempt is possible for all password-based encryption methods, including WPA3.

If Secura is requested to also check the security of the implemented security measures for authorized users, we should be provided with the correct login credentials. This way we can connect to the Wi-Fi network, just like a normal user would, using passwords and certificates.

Additional tests we can perform:

  • How are users separated from each other?
  • Can information sensitive areas of the office automation network be reached?
