NFC and RFID Skimming: how to protect yourself from data theft at close range

NFC (Near Field Communication) and RFID (Radio-Frequency Identification) technologies have become an integral part of our daily lives. These technologies allow us to make contactless payments, access services or transfer data conveniently and quickly. However, with their growing popularity come new threats such as NFC and RFID skimming, methods that attackers use to steal data in your vicinity.

What is NFC and RFID skimming?

NFC skimming is a form of data theft in which an attacker uses NFC technology to steal information from your devices, such as credit cards or smartphones. NFC works over a very short distance, usually within a few centimetres, which allows attackers to stealthily approach close to you and capture data without your knowledge.

How does NFC and RFID skimming work?

Unlike other types of skimming, NFC/RFID skimming does not require extensive technical knowledge and the attacker can even make do with his mobile phone if it has an NFC/RFID reader. The reader can also be a physical device, which can be purchased on various online marketplaces. Since in many cases the content of chip cards is stored in plain text, the attacker has no problem reading and further processing the data according to his needs.

Attackers seek out crowded places for this type of attack, such as shopping malls, public transport or concerts, where the victim is exposed to these attacks and is unlikely to notice such an attack.

Jak se chránit před NFC a RFID skimmingem?

There are several effective ways to protect yourself from NFC and RFID skimming. To ensure that cards and chips are protected, the simplest possible protection is to place them in a protective sleeve or use a blocking anti-skimming card. These products are made of materials that block radio signals, making it impossible for attackers to access your data. You can purchase the card here.

For mobile devices, it is best to turn off NFC and RFID technology whenever you are not using it. While the phone itself has software protection, fewer active signals always means less risk.

Conclusion

NFC and RFID technologies bring many benefits and conveniences to our lives, but they also pose a potential security risk. NFC and RFID skimming are real threats that can lead to the loss of sensitive data and money. However, with a bit of caution and the right precautions, you can effectively protect yourself from these types of attacks and continue to safely enjoy all the benefits these technologies offer. Remembering the basic rules of security will allow you to stay one step ahead of potential attackers and protect your valuable information.
