Public Wi-Fi can be convenient, but it can also expose you to risks such as evil twin attacks, where cybercriminals set up a deceptive Wi-Fi network in the hopes that users will connect to the fake Wi-Fi hotspot instead. This can be hard to spot in busy public places, especially if the network has a similar name to a legitimate Wi-Fi connection.<\/p>\n\n\n\n

Luckily, there are ways to stay vigilant. We\u2019ll explain how an evil twin attack works, what information it can expose, how to spot a suspicious network, and what to do if you connect to one. We\u2019ll also cover best practices for reducing the risks of using public Wi-Fi.<\/p>\n\n\n

    Evil Twin Attack Explained<\/h2>\n\n\n\n

    An evil twin attack is a cyberattack in which an attacker creates a fake Wi-Fi network<\/strong> designed to resemble one offered by a nearby public venue to trick users or devices into connecting to the rogue network.<\/p><\/div>\n\n\n\n

    How Does an Evil Twin Attack Work?<\/h2>\n\n\n\n

    While the exact process can vary, here\u2019s one example of how an evil twin attack may unfold:<\/p>\n\n\n\n

      \n
    1. Find a target:<\/strong> The adversary chooses a busy location with public Wi-Fi, such as a hotel or coffee shop, and collects information about the targeted network.<\/li>\n\n\n\n
    2. Create a rogue access point (AP):<\/strong> The adversary configures a wireless device to imitate the network.<\/li>\n\n\n\n
    3. Get a device to connect:<\/strong> Techniques such as using the same or a similar network name (SSID<\/a>) may be used, and they may also attempt to disrupt the legitimate connection to prompt a device to reconnect.<\/li>\n\n\n\n
    4. Present a fake login page:<\/strong> A captive portal that mimics the venue\u2019s real login process may be used to collect data such as usernames and passwords. This is a form of phishing<\/a>.<\/li>\n\n\n\n
    5. Route the traffic:<\/strong> The rogue AP acts as a gateway between the connected device and the internet, allowing the traffic to pass through the attacker\u2019s equipment.<\/li>\n<\/ol>\n\n\n\n

      What Information Can an Evil Twin Attack Expose?<\/h2>\n\n\n\n

      What an attacker can see or interfere with depends on how the network protects its connection and traffic.<\/strong> Encryption, such as from HTTPS or a VPN<\/a>, can limit what is visible to someone operating the rogue network.<\/p>\n\n\n\n

      If protections are lacking, they may be able to monitor network activity or capture information sent over the connection, including unencrypted messages, personal information, account credentials, and financial information such as banking details.<\/p>\n\n\n\n

      How To Spot an Evil Twin Network Attack<\/h2>\n\n\n\n

      Evil twin networks can be difficult to identify, and no single indicator necessarily means that a network is malicious on its own<\/strong>. However, several unusual signs together indicate that a Wi-Fi network may require extra caution:\u00a0<\/p>\n\n\n\n
