Shopping centers, airports, cafes, shops, libraries, public transportation, and hotel rooms all have free Wi-Fi. Thousands of people often use these networks on a regular basis. As per a recent ITRC survey, three out of every four responders use free public Wi-Fi.
However, most users are unaware that free public Wi-Fi is not secure. Even though you have to enter a password to log in, that doesn’t indicate your online activities are secure. You may enjoy public Wi-Fi, but hackers do as well! So, if you are not using public Wi-Fi security, you are putting your online identity and money at risk.

How can cybercriminals steal your personal information through public Wi-Fi?
There are two types of attacks that cybercriminals can use to get access to personal data and steal your identity through shared public Wi-Fi.
Hackers on the same network
The ultimate goal of a hacker is to connect to a network where several users are already connected, making public Wi-Fi networks great targets. Once he has access to such a network, he can use his strategies to seize control of all data and communications passing through it.
Man in the middle (MITM) is one of the most common techniques used by hackers to intercept data from users on the same network. This is the point at which cyber criminals intercept communications between clients (or public Wi-Fi users) and the public Wi-Fi router. As a result, they can capture and view all entering and outgoing data.
The ability to file share is another risk of being on the same network as the hacker. If you have file-sharing enabled while connected to the network, the hacker can send you malware-infected files. So, it is important for public Wi-Fi security to disable such options.
Hackers who create fake Wi-Fi Hotspot
This is another way for tricking unsuspecting users into joining a fake network set up by the hacker. They can use this to get access to your personal information, such as your social accounts and financial credentials, as well as other sensitive information that is important to your well-being. If you have the file-sharing option enabled on your device, they can also access your files.
Another method is that after you connect to the fake network, hackers can install malware on your device by sending false system upgrade notifications. Instead of upgrading, they install malware that can broadcast your sensitive information in real-time, such as your system’s documents, images, chat logs, and so on.
7 Tips for public Wi-Fi security
If you can’t avoid public Wi-Fi networks, make sure you’re well-protected when you use them. Fortunately, there are several helpful tips you can use to keep yourself safe when using public Wi-Fi networks:
Use a VPN
The most helpful public Wi-Fi security tip is to surf on public networks is to use a VPN (Virtual Private Network). It is one of the most useful tools for assisting users in keeping their information secure while connected to public networks. VPNs encrypt data flow and operate as a secure tunnel between the client (browser) and the server. Hackers will not be able to access your information or your online activity since all data passing through the tunnel will be hidden from them.
Look for HTTPS
If you don’t have access to a VPN, make sure that you only visit encrypted sites that will help protect your data from some of the threats. Look for HTTPS at the start of a website’s URL. This implies that the connection between the browser and the webserver is encrypted, protecting any data submitted to the website from spying or modification. Most browsers additionally provide a padlock icon at the start of the address to show that the site uses encryption.
Protect your password
Hackers could acquire access to your passwords if you use public Wi-Fi. Enabling two-factor authentication, or 2FA, on any services that support it is one option to strengthen your security. When enabled, this added protection assures that even if someone obtains your password while you’re using public Wi-Fi, they won’t be able to access your accounts. Usually, you’ll receive a second log-in step — such as a phone call or a passcode on your smartphone — that you’ll use to access your account. This is the most important tip for public Wi-Fi security.
Consider using a password manager
Another public Wi-Fi security tip is to use a password manager. A password manager can offer an additional layer of security. Password managers are software programs that generate unique, complex passwords for each of your account information and store your usernames and passwords, unlocking them with a fixed strong master password.
This is very useful for public Wi-Fi security. This is because many password managers use secure, high-level encryption, making it impossible for hackers to figure out your login credentials or passwords.
Enable firewall
By enabling the firewall, you can prevent hackers from gaining unauthorized external access to your device. A firewall will not give complete protection, but it is a setting that should be enabled at all times.
A firewall is the best public Wi-Fi security tip that serves as a barrier between your device and data-based malware threats. It regularly monitors network data packets and detects whether they are safe or not. The firewall blocks any harmful data packets it detects. The firewall protects your computer or network and data from threats by blocking specific types of information.
Remember to log out
This is one of the most important tips for public Wi-Fi security. When you’re finished browsing, remember to log out of any services you’ve been using. Check your settings to ensure that your device will ‘forget the network’ and will not automatically reconnect to that network if you are within range without your permission.
Use your mobile data
And last but not least public Wi-Fi security tip. Your mobile data is generally encrypted. If you’re on the go and don’t have access to a secure website or VPN encryption, consider using your mobile data instead of Wi-Fi. This is a smart option for entering personal information into apps because it might be hard to tell if they are encrypted.
Conclusion
Digital security is vital, and users must understand the risks of public Wi-Fi. It can save internet users and their loved ones from being victims of data theft. These public Wi-Fi security tips are simple, easy, and fairly inexpensive, and they could protect you from cybercriminals in any public place.
