Card cloning signs
Cybercriminals have tools to be able to steal bank details and clone the card. An example is if they sneak some malware into the browser and manage to record the information that the victim enters. Also through Trojans or Phishing attacks. But they could even clone your card when paying at a physical site. Now, there are signs that can indicate that there is something wrong.
You see strange operations
Undoubtedly one of the most obvious signs is when you see strange operations. Maybe a payment attempt in the bank app or even see a charge that doesn’t match something you’ve done. That is going to set off the alarms and you may think that your bank card has been cloned.
This type of operation can be carried out by a hacker who has obtained the card data. It could go online and make a payment as if it were really you. But of course, today there are more and more security systems and it is easy to find out that there is something strange, but it does not always happen.
You receive an SMS of a supposed payment
Another sign that you can see is that you receive an SMS with information about a supposed payment. For example, that you receive a verification code to put in the payment process and that it can be done. Be careful with this, since there are banking Trojans that can even read the codes you receive by SMS.
This is a security measure that most bank cards use today. It is a way to prevent anyone, even cloning the card, from making a payment on our behalf. You will need to enter that security code to verify the payment.
Enter the app or page of the bank
Of course, another way to see that they have been able to clone your bank card is to directly access the bank app or website. There you can see all the transactions, see the balance and check that everything is fine or there is something strange. If you see declined payments or anything like that, it could be card theft.
Banks generally inform customers as soon as a transaction occurs. Sometimes through the mobile application, by SMS, by email… Activating these notifications is very useful to detect card cloning.
Tips to avoid problems
After explaining some methods to detect card cloning, we are going to give a series of tips to be properly protected. The objective is to prevent this from happening and that they cannot steal our personal data. Normally these attacks will require us to make a mistake.
Most important of all is the common sense. Avoid installing unofficial apps, be careful what files you download from the Internet and where you log into your bank account. Also, of course, be careful where you are going to make a payment on the network, since that is where they could obtain the data.
You should also always have security programs, in order to prevent the entry of malware. Install a good antivirus that analyzes the files you download and warns you if any problems appear. Also, have updated the system It will be essential to correct vulnerabilities.
Another important issue is always to configure the account so that there are no problems. Enable notifications, to know at all times what could have happened, as well as two-step verification. This will help you protect the bank card and avoid problems.
