Skimming

Sometimes, cybercriminals also install malicious programs on the payment pages of electronic commerce websites. These programs are invisible to the user, but the card data is taken as it is introduced.
In this case, there is not much that users can do to be safe, apart from buying only from big brands and websites, which are probably more secure.
"I've been growing there for the last few years. Although it is not something generalized fortuna. The best thing that can be done to know if we have been victims of this technique is to review if it has been done with our non-authorized payment card. This is also valid for the rest of the cases," points out Albors.

Filtrations

Sometimes card data is stolen directly from the companies you do business with. It can be a provider of health services, an electronic commerce store or a travel company. This is a more profitable way of doing things from the cybercriminal's point of view, because in a single attack they can access a large amount of data.

Public WiFi

When you're away from home, it can be tempting to surf the net for free at public WiFi hotspots, airports, hotels, cafeterias and other shared spaces. Although you have to pay to join the network, it may not be safe if the cybercriminals have done the same thing. You can use this access to spy on your data while you introduce them.
