These 'WiFi' networks require a 'hotspot' machine. Most of the time, this 'hotspot' machine does not have the ability to withstand the virus. As a result, the virus is inserted in the mobile or laptop connected to this 'hotspot'. In the meantime, there are some viruses whose work is to send all information from the device to the hacker.
Sometimes, there are several warning signboards in the public 'WiFi' zone. So that the WiFi zone is warned to use smartphones or laptops with caution. But most of the time people do not care about these signboards.
In the 'Free WiFi' zone one can read a smartphone user or a laptop user's 'Data Communications'.
Also, if hackers get mobile banking accounts, such as account numbers, debit card numbers, PIN numbers, credit card numbers, pin numbers, then the user may be destitute.
These 'free WiFi' connections do not have any password, even its router is too low. As a result, the 'connected WiFi' hacked smartphone can be easily hacked.
Therefore, experts have advised not to connect mobile or laptop anywhere with protected Wi-Fi zones.
