Danger of Public WiFi: Why You Should Think Twice Before Connecting

The digital era presented us with many challenges, but above all, importance is to stay connected. Public WiFi is a great way to access the internet on the go — but is it safe? But while such innocuous networks seem to be harmless there are real threats to your personal data and security online. 

This article highlights the dangers of public WiFi, explains the methods used by cybercriminals, and provides tips to protect yourself when using these networks.

Understanding Public WiFi Networks

Public WiFi networks are generally a wireless internet connection opened for visitors for free or for a small fee to use in public spaces. Private networks don’t have to be unsecured — meaning they lack the encryption needed to keep your data from prying eyes. While they offer great convenience, they also offer a wide attack surface that is attractive to cybercriminals.

The Risks Associated with Public WiFi

• Man-in-the-Middle (MITM) Attacks

 

The most common threat on public WiFi is the Man-in-the-Middle attack. In such a case, a hacker can intercept the communication between your device and the network. This enables them to intercept sensitive information like login credentials, credit card information, and personal messages.

 

• Evil Twin Networks

Hackers set up fake WiFi networks disguised as legitimate ones. These so-called “evil twin” networks deceive users into connecting to them, giving hackers the ability to spy on and steal their data.

 

• Data Sniffing

One of the data sniffing which detecting and analyzing data packets from the network. On unsecured networks, hackers can use common tools to break into your personal information, including email, passwords and browsing history.

 

• Malware Distribution

Public WiFi networks are a distribution channel for malware. Hackers can take advantage of your device vulnerabilities or infect you with malicious software by getting you to download bogus software update prompts.

 

• Session Hijacking

Session hijacking refers to stealing your session cookies so that the attacker can access your accounts without going back to the login form. This can be on websites you’ve signed into during sessions on public WiFi.

 

• Unencrypted Networks

The data you’re truly vulnerable to be intercepted, as most public WiFi networks are not encrypted. Any information you send or receive without encryption can be intercepted and read by others.

 

Real-World Examples of Public WiFi Threats

• The Coffee Shop Incident

In 2017, a cybersecurity researcher showed how easy it is to get into public WiFi networks. They created a simple rogue access point in a coffee shop, and there, they were able to accumulate personal information for unsuspecting users.

 

• Airport WiFi Hack

Airports are a hotbed of public WiFi usage and, likewise, attempted hacking. In one notorious instance, hackers set up a fraudulent WiFi hotspot in an airport, harvesting information from hundreds of travelers.

 

How to Stay Safe on Public WiFi

• Avoid Accessing Sensitive Accounts

 

Do not sign in to sensitive accounts (online banking, email, etc.) when using public WiFi. If you have to access these accounts, do so with a VPN.

 

• Turn Off Sharing

 

Once connected to the public WiFi, turn off file share and other sharing options on your device. This minimizes the chances of having your files accessed without permission.

 

• Keep Software Updated

 

Make sure your device’s operating system, apps and antivirus software are current. “Upgrades frequently contain security updates to mitigate known vulnerabilities.

 

• Verify the Network

 

Make sure to confirm the name of the network with the establishment providing the WiFi before connecting. Do not connect to networks with strange names.

 

• Use Two-Factor Authentication (2FA)

 

Use two-factor authentication on your accounts. Even if a hacker gets your password, they will need the second authentication factor to sign in.

 

• Log Out When Done

 

When you are finished with public WiFi, always log out of your accounts and disconnect from the network.
