WiFi is everywhere nowadays. How do you know if the WiFi network you are on is safe and secure? The truth is it is very hard to tell whether a network is secured when you are connecting to it in a coffee shop, hotel, airport or even your neighbor’s house.
Wireless networks have been subjected to an attack called the “Evil Twin Attack”. An Evil Twin attack is a fraudulent WiFi access point that looks to be a legitimate set up, but it actually eavesdrops on wireless communications. As far as wireless LAN goes, this is the equivalent of an email phishing scam. It is very hard to detect and you need to be on your toes at all times. The Evil Twin attack is designed to steal passwords of unsuspecting users by monitoring connections or phishing, which involves a fake website and luring people to the location.
So, how can this tactic obtain your information?
After you are lured onto the bogus wireless access point, the hacker will prompt you to enter sensitive information, making it look like you need to connect to the wireless internet. Once, your information is entered, the hacker has access to every website you go to that is unsecured (non-HTTPS). For example; when you log into an unsecured bank or email account, the attacker interrupts the transaction and sends it through their equipment, which gives them all the information they need to access your accounts later. This Evil Twin attack can be set up to pass internet traffic through to the legitimate access point while monitoring the victims connection, or it can produce a message that says the system is temporarily unavailable after the hacker obtains a username and password.
