Public Wifi helps you connect to the Internet for free. However, is it safe to use public wifi? Let's find out with Download.vn !
Public wifi is free but potentially dangerous
Have you heard stories like not being able to open PayPal, bank accounts, even emails when using public Wi-Fi ? So what are the real dangers of using public Wifi ?
Home Wi-Fi is usually encrypted, but at cafes, airports, stores... it's the opposite. That means you're risking someone else monitoring your online activities, sometimes worse than that. Here are the dangers you need to know when using public Wifi.
Risks when using public Wifi
Browsing the web publicly
Not protected when using public Wifi
Wi-Fi uses radio waves. They can be anything, except live broadcast. Because it's broadcast wide, it means anyone within range can see everything you're doing online if they're using the right software.
Thus, without protection, anyone can see:
- Every page you visit
- Every message you send
- Login information to different sites
Can infect people who share the Internet with you
Vulnerable to malware from others when using public Wifi
Being tracked isn't the only potential danger when using public Wi-Fi. Malware infection is another risk. Networks are not a one-way connection between you and the Internet. They indirectly connect you to devices that are sharing the same network.
For example, someone's computer or phone is faulty and has no malware protection. They connect the device to the public Wifi you are using. At that time, any malware on their machine can infect your phone or PC.
Wifi networks can be a pitfall
Pitfalls are always hidden in free Wifi
Although public Wifi is becoming more and more popular today, however, if it is not absolutely necessary, you should limit its use. If you must, do not access applications that contain your personal information or sensitive data. Why so?
Connecting to a random network with an unknown provider can be fraught with pitfalls. Scammers often set up fake Wi-Fi networks in public places in hopes of stealing passwords and personal information. If connecting to a network like Free Wi-Fi, which doesn't require a password or welcome screen, can be a pitfall.
Think carefully before connecting to Wi-Fi
Basically, you need to remember the following before using public Wifi if you want to keep yourself safe:
- If online activity is not encrypted, it will be public to anyone who wants to see it.
- Make sure your firewall is turned on and your anti-malware protection is up to date.
- Consider using public Wi-Fi through an encrypted VPN service.
