Risks associated with public Wi-Fi

1️⃣ Data piracy

Cybercriminals can intercept data exchanged over an unsecured network. They use tools such as “sniffers” to capture your passwords, e-mails or banking information.  Read our article about passwords to create one that is truly secure.

2️⃣ Identity theft

By accessing your personal information, hackers can impersonate you to carry out fraudulent transactions or gain access to your accounts.

3️⃣ Malicious Wi-Fi networks

Scammers create fake access points that resemble those in public places. Once logged in, you give them direct access to your device.

4️⃣ Malware injection

Hackers can exploit network vulnerabilities to inject malware into your device. These programs can lie dormant or cause immediate damage.

How to protect yourself on public Wi-Fi?

🛡️ 1. Use a VPN (Virtual Private Network)

A VPN encrypts your data, making it unreadable to hackers. It is one of the best solutions for securing your connections. For example, you can use NordVPN or ExpressVPN

🛡️ 2. Avoid sensitive connections

Don't check your bank accounts or make online purchases while connected to public Wi-Fi.

🛡️ 3. Disable automatic connections

Your device may automatically connect to known or similar networks. Deactivate this option to maintain control.

🛡️ 4. Prefer mobile data

For sensitive tasks, prefer your cellular connection, which is generally more secure.

🛡️ 5. Activate two-factor authentication

Even if a password is compromised, a second layer of security can prevent unauthorised access to your accounts. To set up this system, use your telephone number or app like Google Authenticator.
