Free public Wi-Fi is now available in many places, airports, hotels, cafes, etc.. For many people, free public Wi-Fi seems to be the ideal choice to get access their work emails or sharing documents online for people who are traveling.

However, the risk of using public Wi-Fi hotspots is higher. Most public Wi-fi hotspots do not encrypt the information you send over the Internet. When you connect to the public Wi-fi network, when you are sending your personal information through the website and mobile devices through the Wi-fi network, it is so easy for hackers to invade and damage your information.

One of the most common public cyber threats is called a man-in-the-middle (MitM) attack. When a malicious actor manages to intercept communications between the two parties, a man-in-the-middle (MitM) attack occurs. There are various types of man-in-the-middle attacks, but the most common one is to intercept a user's request to access a website and send a seemingly legitimate fraudulent webpage in response. This can happen on almost any website, from online banking to file sharing and email providers. For example, if ...
... a hacker prepares to intercept communication between your device and an email provider when you try to access your email, he can perform a man-in-the-middle attack to induce you to enter a fake website. If the hacker gets your login name and password, he can use your email to perform more malicious operations, such as sending phishing emails in your contact list.

Another danger is fake hotpot. The hackers can set up fake hotspots with names very similar to that of the public Wi-Fi. For example, when you enter a Starbucks coffee shop, there are three Wi-Fi networks with similar names: Starbucks, Starbucks01 and Starbucks02. It is likely that at least one of them is the fake Wi-Fi built by the hackers. When you are operating in this kind of network, the transmitted data can be monitored by a third party. If you log in to the account, the hackers can find your login information from the data packet and steal information such as personal mailboxes and e-commerce accounts.

Hackers can use special software and devices to monitor Wi-Fi signals, and get all the information you have in your browsing history and fill in, including login authentication or credit card details.

Cookies are files on your computer that are used to store login details for a specific period of time, so you don’t have to enter a user name and password every time you open a website. And stealing this information is easier than you think. By hijacking the browser session, hackers can log in to your account and impersonate you.

Unfortunately, even for an inexperienced hacker, all these techniques are easy, so it is very important to understand the possible threats and learn how to protect yourself.

To protect ourselves on public Wi-Fi, it is advised to turn off any settings that allow your device to automatically connect to available Wi-Fi networks and turn off file sharing and log out of your unused account.

Do not just connect to any WiFi. If you see two WiFi names that look similar, remember that one of them may be fake. Therefore, before joining the free public network, it is best to review with the staff.

If you use public Wi-Fi, avoid entering your bank account and other sensitive accounts including your work email and social networking sites, because people tend to share private information through these channels.

Turn off file sharing and check the firewall. For security reasons, it is best to turn off file sharing on your computer on a public network. If you turn on this feature at home, you can easily share files on your device. However, this means that it is also easy to share them without public Wi-Fi that you know, so remember to turn it off before connecting. When you turn off the sharing option, please continue to check whether your firewall is turned on.

It is better to use password-protected Wi-Fi hotpots whenever possible. If you have no choice but to use a public Wi-Fi network, try not to send or access sensitive information. Or, you can use a VPN.

VPN (Virtual Private Network) is a secure connection established through a public network. VPN mainly uses tunnel technology, encryption and decryption technology, key management technology and user and device identity authentication technology. A secure VPN uses an encrypted tunneling protocol to provide confidentiality by preventing interception and sniffing. It also allows sender authentication to prevent identity forgery, while providing message integrity by preventing information from being modified.

By using a VPN when connected to a public Wi-Fi network, you will be able to effectively use a "dedicated channel" to encrypt all your data through that network. This will help prevent hacker lurking in the network from intercepting your data.

More importantly, VPN allows you to hide your location by replacing your IP address with the IP of your remote VPN server. This not only helps protect your identity from hackers, ISPs and other snoopers, but also allows you to safely access restricted websites. This is especially convenient if you travel abroad and want to access your favorite content and social media services.

After installing the VPN application on your mobile phone, laptop or tablet, all you have to do is connect to a remote VPN server, and you can join any wireless network without risking you becoming a hacker victim.

There are so many VPN services online. It can be confused as to which to choose. If you want to buy a VPN for family use, you should look for a router-based VPN, or one that allows multiple simultaneous connections. If you want to stream movies online, you need a VPN with fast speed, stable connection and unlimited bandwidth. For tourists who rely on public Wi-Fi networks, a VPN that provides high security and servers all over the world is a better choice. Although free VPN is very attractive, it is not recommended. Just like free public Wi-fi, it will not be real “free”. You may pay for it in another way, whether the annoying advertisements, leaky protection, or low speed.

BitVPN is a decentralized VPN developed on the decentralized P2P mesh network. Different from the traditional centralized VPNs, the traffic is distributed to the whole network instead of a single server, so it can do a better job in protecting your online security and privacy on public Wi-Fi network.
