How to stay safe on public WiFi networks

Public WiFi is popular and can be found in hotels, restaurants, coffee shops - often allowing free access to the internet. We usually don't think twice about connecting to public WiFi, even though we have no idea who is actually supplying the 'Hotspot' or the dangers we are exposed to.

What are the risks of Public WiFi?

Malicious WiFi Hotspot

Just because a WiFi network is called the same name as your favourite coffee shop, doesn’t mean that it is the coffee shop’s WiFi. Anyone can setup a WiFi hotspot with any name and allow anyone to connect for free and without a password. Once connected to a malicious hotspot your internet traffic can be monitored and your internet device hacked!public wifi

Imposter WiFi Hotspot

Very similar to a malicious hotspot, an imposter hotspot is setup with the same WiFi name and password as a genuine public hotspot. Your internet device will only see one WiFi network name and there’s a 50/50 chance that it will connect to the imposter WiFi. 

Man In the Middle Attack

This type of attack is usually based on a vulnerability and happens when your internet device connects to an internet resource, like a website. This type of attack allows the attacker to jump into your connection without you knowing and eavesdrop on all the communication.

Network Sniffing

Using special software and WiFi equipment a hacker can see all wireless internet traffic allowing him to access everything you’re doing online. This includes obtaining information such as passwords, information entered on website forms and even hijack your accounts
All of the above are usually carried out without you even knowing it’s happened. It can be days or even weeks before you find that your online accounts have been compromised or you suddenly start getting unexpected charges on your bank cards or you suddenly receive details of mobile phone contracts you didn’t sign up for!
