Whether you"re in an airport, in a coffee shop, or a library, không lấy phí Wi-Fi is available almost everywhere these days. Unfortunately, not all không tính tiền Wi-Fi networks are vigilantly protected when it comes lớn their IT security.

That Wi-Fi network you"re using could be open to security threats by hackers & cybercriminals, putting your personal information at risk. Here"s what you need to lớn know about fake Wi-Fi networks.


Public Wi-Fi is often a target for Man in the Middle (MITM) attacks. According lớn SaferVPN, up to 25 percent of all public hotspots are used by hackers to lớn access your personal information.

Besides taking advantage of any insecure Wi-Fi networks lớn steal your identity, two additional Wi-Fi vulnerabilities that hackers can use are Rogue Access Points (AP) và Evil Twins. These are seemingly genuine wireless networks created khổng lồ trick potential victims into giving away their personal information.

They can look and act as what you would expect from a real network. This includes using the same or similar name (think Starbucks Wi-fi versus Starbucks không tính phí Wi-Fi), and the same login screen.

While connected khổng lồ an insecure và unencrypted network, you are at minimum giving the hacker miễn phí access lớn anything you vì while online. This includes grabbing any usernames, passwords & other personal information that you enter.

At most you"ll tải về a vi khuẩn or malware và give them full access to lớn your device even after you disconnect from the insecure "network".

If you connect to lớn a network where a credit card is required for access, lượt thích a hotel, or an airplane "pay per hour" network, the hacker will have copied your credit card info even before you start browsing. In short, any data you upload or download while on the hacker"s Wi-Fi is visible khổng lồ them.

While there are other ways hackers can use public Wi-Fi to lớn steal your identity, we"re going to lớn focus on what Evil Twins and Rogue Access Points are, what khổng lồ look for, and what you should bởi if you connect khổng lồ one.

What Is a Rogue Access Point (AP)?


A Rogue AP, sometimes used interchangeably with Evil Twin, is an insecure device connected lớn a network unbeknownst to lớn the owner. This device will broadcast its own Wi-Fi that will connect you to the genuine network created by the business.

It will seem lượt thích connecting to lớn the Wi-Fi as normal, but your connection will go via the hacker"s access point instead of the intended secure device.

A tin tặc will usually combine this with a Denial of Service attack on the original access point lớn disable it, making theirs the only available signal.

Rogue Access Points are a massive security issue that threaten the security of all the connected users. Any network security features & firewalls that may be enabled on the network will not affect a Rogue APs access khổng lồ your transmitted data.

What Is an Evil Twin Wi-Fi Network?

An Evil Twin is technically a type of Rogue Access Point that can be mix up with any phone or máy tính xách tay with wireless capabilities. It differs in that it"s not strictly connected to the business" Wi-Fi unknowingly. The hacker will mix up a duplicate wireless network that also looks and acts the same way as the original network, down khổng lồ using the same name và seemingly the same security features.

The signal of this Wi-Fi will usually overpower that of the real network, simply by being physically closer to the user. Again, a Denial of Service attack lớn knock out the original access point is not uncommon in this scenario.

Either way, this means that potential victims will connect to the hacker"s signal rather than the genuine network.

How to lớn Spot an Evil Twin Wi-Fi Network

Unfortunately, in real life, evil twins don"t wear goatees lớn make them easy to lớn identify. Don"t assume that because the name of the Wi-Fi is "Starbucks không tính tiền Wi-fi", that it is secure, or even that it belongs to Starbucks.

Oddly enough, the easiest Evil Twins to lớn spot can be those that are password protected. If you purposely enter the wrong password and you don"t get an error message, the access point is likely fake. An Evil Twins will commonly let anyone access it regardless of the password you enter.

Look out for very slow network connections. This could be a sign that the hacker is using mobile internet khổng lồ connect you khổng lồ the web.

Also, pay attention to the address bar of the websites you visit. If your banking trang web shows an unencrypted HTTP version instead of HTTPS, your connection is definitely unsafe. This is called SSL Stripping, & a hacker can get your passwords or banking details as you enter them.

It"s easy for a hacker to redirect you khổng lồ a fake version of any website if you connect through their device, & this way, they can get your login details as soon as you enter them. Using a VPN will not protect you in these cases, as you are entering your information into the hacker"s own website.

However, make sure that the URL is correct, and look out for grammatical errors or language that you would not expect from the website.
