5 Wifi Vulnerabilities Everyone Must Know

There are many vulnerabilities in wifi networks that compromise their security. After reading this article, you might think about using Data Connection or Ethernet instead of using wifi, so keep reading!

The Public Wifi

Who doesn’t like getting connected to the free wifi at the coffee shop? Well, after reading the following facts, you will think again before using public wifi.

Public wifi networks are more vulnerable to wireless attacks. Hackers can easily read or modify the data you are sending or receiving over a wifi network.

Therefore, you should rely on your mobile data connection instead of the lucrative free wifi if you are outside your office. Make sure that you don’t have a shared wifi connection in your office either.

Consider using Ethernet instead of wifi for a securer, faster, and reliable internet connection. You can buy a USB to Ethernet adapter for your laptops and PCs at the UGREEN website.

Evil Twins

Evil Twins is one of the most popular ways of getting your data without your consent over a wifi network. What hackers do is that they set up a fake wifi network and disguise it to make you think that you’re connecting to a legitimate wifi network.

Once you are connected, hackers can get all the information about your device, what websites you are visiting and what data you are sending or receiving.

Avoid using ANY wifi network outside your home unless you are 100% sure about the security of a wifi network.

Packet Sniffing Attacks

A Packet Sniffing attack is another common wifi attack that affects various wifi users around the world. This attack stems from the principle that whatever you send over a wifi network can be intercepted by a third party if there’s not a secure encryption. Packet Sniffing attacks allow the hackers to find all the details you are sharing over a wifi network.

Sadly, there is no way of telling if you are secure from a Packet Sniffer attack or not. The only option you have is avoiding free/public wifi networks at all costs.

File-Sharing Threats

File-Sharing is an option in computers and smartphones that is activated by default most of the time. This feature makes it super easy for a person to share files between different devices.

But the downside is that hackers can easily exploit its functionality and use it for accessing secure files on your device.

If you get connected to an insecure hotspot connection, hackers can make their way to the files stored on your computer and pick whatever they want!

Hackers can even leave infected files/malware on your device if they have access to the files with this File-Sharing feature.


As the name suggests, this type of attack involves the addition of an unauthorized person when you send or receive any data using a wifi network. These attacks can occur over any network but planning and putting them in place is super easy over unprotected wifi networks.

Hackers make their victims think if they are communicating with each other. But in reality, the hacker knows exactly what is being discussed between different users.

Hackers who have adequate knowledge of social engineering can execute such attacks and walk away, stealing anyone’s data over the wifi network.


Always keep in mind that only YOU are responsible for keeping your information safe over the internet. Avoid using public wifi networks, download files over dubious websites and stay informed about the latest developments in technology.
