That requires us to know more about the attacks and strategies that are in place so that your loss will be minimized. An evil twin attack is one of the network attacks.

Evil twin attackers create a fake Wi-Fi access point that mimics a legitimate network to trick people, and once people connect to this fake network, all information from their network traffic to private login credentials will be available for attackers.

It is hard to identify which network is the real one and most users even have no idea of this attack. When you go to a café for free Wi-Fi, typically, people will ignore its potential danger and this attack can be a success.

This “evil twin” can be created on all Internet-capable devices but the attacks are more common on public Wi-Fi networks which are unsecured and leave your personal data vulnerable.

How Does an Evil Twin Attack Work?

There are five major steps in an evil twin attack.

Step 1: Locate a Wi-Fi Target

Usually, attackers will find the right place with free and popular Wi-Fi, like some public places – café, libraries, restaurants, etc. Those places with high visitor flow can be the best choice to execute this attack and nobody will notice that.

Step 2: Set up a Wi-Fi Access Point

After they have determined the location, they will create a new hotspot using the same Service Set Identifier (SSID) name as the legitimate network, so that users will mistake the access point and fall into the trap.

Step 3: Set up Fake Captive Portal Page

Many users may have ever encountered this situation. When you try to access a public Wi-Fi network, then a page will pop out to ask for some basic information before the connection.

That can’t make you certain of the illegitimacy because many legitimate networks will do so. Hackers can easily replicate them to trick users into sending over their login information. That’s dangerous.

Step 4: Trick People into Using the Evil Twin Wi-Fi

The hackers will move closer to the victims so that the fake network signal will be stronger, attracting people to connect to the fake one over the weaker ones.

Step 5: Steal Victims’ Data

Once the connection success, attackers will monitor the victim’s online activity with a man-in-the-middle attack. In this way, if you input any login credentials and passwords, that information will be exposed in front of attackers. Your privacy cannot be guaranteed.

How to Prevent an Evil Twin Attack?

5. When you are using a public network, make sure you only visit HTTPS websites that have end-to-end encryption.

6. Disable the auto-connect feature. Sometimes, this feature will make your Internet automatically connect to the strongest open Wi-Fi and that can be dangerous.

7. Limit your online activities when you are using a public network. Don’t expose your important information in public. You can do some usual entertainment when accessing an open Wi-Fi but don’t input your password or look through some important data.
