An evil twin attack is a type of Wi-Fi attack where an attacker creates a fake Wi-Fi access point that looks identical to a legitimate one. The attacker then uses this fake access point to trick users into connecting to it, allowing the attacker to eavesdrop on their traffic and even inject malicious content.

There are a few different ways that evil twin attacks can be carried out, but the most common is by setting up a fake access point using a laptop or other portable device. The attacker will choose a name for their fake access point that is similar to a legitimate one in the area, making it more likely that users will connect to it. They will then use special software to route all traffic from the fake access point through their own device, allowing them to monitor or even modify it.

While evil twin attacks can be difficult to detect, there are a few things that you can do to protect yourself. First, make sure that you only connect to Wi-Fi networks that you trust. If you’re not sure if a network is legitimate, ask a staff member or look for other signs that it might be fake.

You can also install a VPN on your device, which will encrypt all of your traffic and make it more difficult for attackers to snoop on your data. Finally, make sure that you have a good antivirus program installed on your device, as this can help to detect and block malicious content that might be injected by an attacker.
