There are many ways in which you can be targeted. Here we discuss some of them so as to give you an idea about how serious the situation is and why you need to take immediate action.

Hackers/ Snoops:

This is the most common way in which you can be attacked. Hackers or snoops are people who enter your computer system forcibly to steal confidential data.  They jeopardize the security of the computer and leave all files present vulnerable to getting leaked and stolen. They can also hack your email and social media accounts by cracking your passwords. Hackers are also adept at breaking into your Net Banking with the intention of draining out money from your account. Hence, these people are extremely dangerous and will go to any level in order to make you part with your data and money.

Man In The Middle Attacks:

There are times when an attacker intercepts the private conversation that goes on between two individuals and tries to alter it according to his or her wishes. The parties of the conversation don’t realize this and feel that they are having a natural conversation. This is called as active eavesdropping where all the data exchanged is controlled at the whims and fancies of the attacker. As the conversation is intercepted by someone who comes in between the two parties, it is called as a man in the middle attack.


Malware is basically a program that has malicious intent and enters your system with the sole intention of harming your computer. The most common forms of malware include viruses, worms and Trojans that can create havoc in your system. It is very easy for malware to enter your system when you are using a public Wi-Fi. However, using a VPN can protect you from the same as it can keep your identity a secret.

Fake Networks/ Rogue Hotspots:

There are cases where criminals and other nefarious people establish their own hotspots and try to trick you into entering them. These hotspots are called fake networks or rogue hotspots. They appear like genuine hotspots but the moment you enter them, all your personal data is compromised. Hence, you need to be wary of logging on to any suspicious hotspot that may harm your device as well as your identity.


As mentioned earlier, logging on with a VPN will make your system very secure as it will protect you from being targeted by such kinds of people. Hence, you need to make sure to use this service the next time you use public Wi-Fi.

  1. As most of the people I am always connecting to public wifi, and because of the security reasons, I am using Nordvpn app. I disagree just with one point in your article, about free vpns. I do not recommend to try them, because as I know, most of them sell your data to third parties. So that is why I trust just paid vpns with a strict zero log policy.
