How to tackle the evil twin hotspot threats in public Wi-Fi

The cybercriminals have become more intelligent than ever before. So the IT managers must also devise smart strategies to outsmart these hackers.

The new buzz in public Wi-Fi security is the “evil twin”. The hackers are using this approach to impersonate and logon to the network as a legitimate hotspot. These attacks are on the rise and the access points in restaurants, retail establishments etc. have become an easy target.

The risk of evil twin

The cybercriminals create twin hotspots. So the remote workers are unaware that there exists a legitimate hotspot against their user-name.

These twin hotspots allow the hackers to intercept the corporate data and maliciously use the sensitive information. The hackers can sneak into the network traffic and data conversation. They steal the information before it reaches the destination servers or to the end-users.

How twin evils are created?

The cybercriminals trick the users and entice them to develop connection with illegitimate hotspots. The users are redirected to various phishing sites and their account IDs, passwords are exposed to these interceptors.

In addition, the interceptors on the evil twin can view the data files being shared between the server and mobile worker.



How users are tricked into developing connection?

The cybercriminal use the same network name for the fake hotspot. So the users think that they have established connectivity with the right Wi-Fi access point.

You are unaware that interceptors are stealing your sensitive data, login/passwords and credit card numbers. Nowadays, evil twin challenge has become the biggest nightmare for organizations supporting remote workers.

The solution

Majority of the IT managers go for wireless encryption for these types of attacks, but this approach has not been successful. The reason is that the Wi-Fi protected access will perform encryption after the link has been established between access point and the user’s devices.

So how can we tackle with the evil twin hotspots, when they cannot be easily detected? The best solution is:

  • Two factor verification

This process can be combined with VPN, and the users can block the evil twin attacks.

  • Add an additional level of encryption

This smart strategy makes it more difficult for the interceptors to read the corporate data files.

  • Enforcement of HTTPS connectivity

Ensures secure data transfer and all interception threats can be blocked.


The implementation of VPN and the 2 factor authentication were very expensive in the past, and therefore only the large-budget enterprises used this technique. But nowadays the growing numbers of cloud-based service providers have made VPN highly affordable for small/medium enterprises as well.

These simple techniques can make your remote data access safe, and the mobile workforce can confidently connect to the corporate server without compromising on data integrity.
