Risks of Using Public Wi-Fi in Public Places Like Malls and Airports: Your Bank Balance Could Be Stolen

The use of public Wi-Fi in places like malls and airports is becoming increasingly common. While it offers convenience, there are several risks to be aware of. Here are the main risks associated with using public Wi-Fi.

1. Personal Data Security

One of the biggest risks when using public Wi-Fi is the security of personal data. Unencrypted networks allow hackers to access sensitive information such as passwords, credit card numbers, and other personal data. A "man-in-the-middle" attack enables attackers to intercept communication between the user and the server.

2. Malware Attacks

Public Wi-Fi networks are often targets for malware distribution. Attackers can inject malware into devices connected to the network. This can happen through downloaded files or by exploiting security vulnerabilities in devices that are not updated.

3. Phishing

Public Wi-Fi can also be used for phishing attacks. Attackers can create fake hotspots with names similar to legitimate networks to lure users in. Once connected, they can easily harvest login credentials and other sensitive information.

4. Unstable Connections

Public Wi-Fi networks are often unstable, which can cause issues when trying to access important information. Slow or dropped connections can be problematic when performing financial transactions or accessing critical data.

5. Privacy Limitations

When using public Wi-Fi, your online activities can be monitored by other users on the same network. This means that your information, such as the websites you visit or the data you send, can be accessed by others.
 

How to Protect Yourself When Using Public Wi-Fi

Despite the risks, there are steps you can take to protect yourself:

• Use a VPN: A Virtual Private Network (VPN) encrypts your connection, making it more difficult for attackers to access your data.
• Avoid Sensitive Transactions: If possible, avoid conducting financial transactions or entering sensitive information while connected to public Wi-Fi.
• Check Network Security: Ensure that you are connected to the correct network. Verify the network name to avoid connecting to a malicious hotspot.
• Turn Off File Sharing: Disable file sharing settings on your device when connected to public networks.
• Update Your Devices: Keep your software and apps updated to close security vulnerabilities.
