Have you found the ideal card for your profile? Find out now how fraudsters steal credit card data.

Furthermore, card data theft is more common than you might think. The transfer of data from your plastic to another can happen at ATMs or during purchases in physical stores and online in apps.

Did you know that even the CVV number (Card Verification Value), the famous security code behind the card, is the target of fraud. 

We are sure that all this has caused a lot of concern and it is not for less. But, you need to know the possibilities of credit card data theft to be able to protect yourself. Therefore, read our text and check everything on this subject. So let's go!

In science, cloning means “production of genetically identical cells or individuals”. In the financial world, cloning is the theft of credit card data in order to transfer it to another. 

A survey carried out by the company PSafe, leader in cybersecurity solutions, points out that 17% of people have already had a cloned card. Serasa, a Brazilian credit analysis and information company, reveals that Brazilians suffer fraud attempts every 8 seconds. 

So what is the information siphoned off of the cards? Your full name, expiration date, card number and security code are what criminals take to shop and carry out other scams to leave you with the biggest headache. 

In addition, the black magnetic stripe located behind the card, which, although it does not have personal information, but keeps the card's security items, can also be invaded and have its data stolen.

First, if the security code is one of the stolen pieces of information, what should you do to protect it? Before the answer, you need to understand what it is for. 

The security code is on the back of the card. It usually consists of three numbers, however, on American Express cards there are four. The purpose of this code is to prove the ownership of the card, that is, that you are the owner. 

Incidentally, the use of the security code is for online purchases, replacing the password. 

And how can it be stolen? To answer that, we need to explain that there is a world called the dark web. The dark web are “invisible” sites, that is, Google cannot identify them and access is only with specific browsers for this purpose. 

The dark web is heavily used for criminal purposes and your card code can end up on it. Data related to bank cards appears as “fullz”, English slang meaning something like "complete information". The person who stole this information can make money by selling it to another criminal. 

The unanswered question is: how is the security code so exposed as to be captured and taken to a deep layer of the internet? To answer that, we have to talk a little about technology.

The PCI DSS, Payment Card Industry Data Security Standard, in English, Payment Card Industry Data Security is a security standard that protects bank card data. And to accept card payments, you must obey the premise of not storing the security code after the purchase is authorized.

It can happen that a store complies with the PCI requirement on a single day of the year and is unprotected the rest of the year. And if you buy on a day when the establishment is vulnerable, this information can be seen by those who shouldn't. If this happens, whoever has your CPF will easily use the CVV for purchases on the internet.

While the issue of PCI DSS is important, experts say attacks against personal computers are the most concrete way to steal credit card information, particularly the security code. Find out about the 4 most common types of attacks for this purpose, below.
