The Secret to Staying Safe on Public WiFi Networks

Public WiFi networks can be great. They provide free, easy access to the internet, often with improved speeds and a stable connection. Of course, if you use them, then your data is a lot more vulnerable to hackers and scammers.

With that in mind, there are steps you can take to keep yourself safe when using a public WiFi network. If you’re interested in staying safe online, then keep reading our short guide.

Understanding the Risks of Public WiFi

One major threat posed by public WiFi networks is the use of malicious hotspots. Commonly found in high-traffic areas, like coffee shops and airports, a hacker will set-up an open network with an unassuming name. The hope is that passers by will connect to it, and use that internet connection to access their emails, bank account, or other private information.

This data traffic can all be recorded by the hacker's device, giving them access to your personal information and exposing you to fraud. Even if you use a genuine WiFi network, if it’s unsecured or not password protected, then it’s still vulnerable to hackers and malicious use.

Recognising Real-World Cyber Threats

When we think of cyberattacks, many people tend to think of attacks against companies, where data is stolen and then leaked online. You may be aware of the PlayStation cyber-attack in 2024, which affected 77 million accounts. While that’s an example of a high-profile, targeted attack, untargeted attacks are indiscriminate and far more common. 

There are several types of real-world cyber threats you can face, especially if you’re a business. These are:

• Social Engineering:
  Individuals are tricked into handing over specific information, which is later used to gain unauthorised access.
  
  
• Phishing:
  By pretending to be a trusted person or company, the user will click a link or share personal information.
  
  
• Malware:
  Harmful software, which is often mistakenly downloaded, gives hackers access to your device.
  
  
• Spoofing:
  By changing the appearance of their contact information, scammers can appear as legitimate, tricking users into sharing sensitive information.

Enhancing Security with Virtual Private Networks (VPNs)

While there is no single solution to every online threat, there are various ways you can minimise the risk. VPNs, for instance, provide an added layer of security to your data by encrypting it at two separate points.

So, how does a VPN work? Ultimately, a VPN works by connecting your device to a dedicated server somewhere else in the world. This connection is encrypted, so only that server and your device know what information is being transferred.

This means that if a malicious user is trying to spy on your internet traffic while you’re connected to an open network, they’ll only view the encrypted data, instead of your actual traffic.

By hiding your data under this additional layer, it means you can check your bank accounts, emails, and other private information without fear of it falling into someone else’s hands.
