RFID / NFC Attacks

NFC (Near Field Communication) and RFID (Radio Frequency Identification) are both wireless communication technologies that enable data transfer between devices over short distances. While they have similarities, there are some key differences between NFC and RFID:
Communication Range: NFC has a very short-range communication distance, typically within a few centimeters. In contrast, RFID can have a range of several meters, depending on the frequency and power of the RFID system.
Operating Frequency: NFC operates at 13.56 MHz, while RFID can operate at different frequencies, including low frequency (LF), high frequency (HF), and ultra-high frequency (UHF).
Communication Mode: NFC supports two communication modes: read/write and card emulation. It allows devices to read and write data to NFC tags, as well as emulate NFC cards for contactless payments or access control. RFID, on the other hand, typically operates in a read-only mode, where tags transmit data to RFID readers.
Security: NFC includes built-in security features to ensure secure communication between devices. It supports encryption and authentication protocols to protect data during transmission. RFID, especially LF and HF RFID, generally have fewer security features, and security measures may need to be implemented at the application level.
Applications: NFC is commonly used for mobile payments, access control systems, public transportation cards, and data transfer between devices like smartphones and smartwatches. RFID is used in a wide range of applications, including inventory management, asset tracking, contactless payment cards, and electronic toll collection systems.
In terms of security, both NFC and RFID technologies can be vulnerable to certain attacks. For example, unauthorized reading or cloning of NFC or RFID tags can occur if proper security measures are not implemented. Protecting NFC and RFID systems involves using secure communication protocols, encrypting sensitive data, and ensuring that devices and tags are properly authenticated.

The ICopy-X is a powerful portable RFID cloning device, built on top of a Proxmark 3 RDV 4.01 It is an entirely stand-alone device with integrated screen and buttons - unlocking the power of a Proxmark but without the need for an external computer.
It supports the full range of standard high-frequency (13.56MHz) and low-frequency (125KHz) cards supported by the Proxmark 3, and also several other previously impossible tag types.
The Proxmark 3 is a popular open-source RFID/NFC research tool that allows for the exploration, analysis, and manipulation of RFID and NFC systems. It is widely used by security researchers, penetration testers, and enthusiasts to understand the vulnerabilities and weaknesses in RFID and NFC technologies.
The Proxmark 3 provides a wide range of functionalities, including reading and cloning RFID/NFC cards, conducting replay attacks, sniffing and capturing RFID/NFC communication, and even emulating RFID/NFC cards for testing purposes. It supports various RFID and NFC standards, such as EM410x, HID Prox, Mifare Classic, DESFire, and many more.
An RFID field detector, also known as an RFID scanner or RFID reader, is a device used to detect and analyze RFID (Radio Frequency Identification) signals. It helps identify the presence of RFID tags and provides information about the frequency, signal strength, and other parameters related to the RFID communication.
The RFID field detector typically consists of an antenna and a receiver circuit that can detect and process the electromagnetic signals emitted by RFID tags. When the detector is brought near an RFID tag, it captures the radio frequency signals emitted by the tag and interprets the data. It can provide real-time feedback on the presence of RFID tags in the vicinity and their signal characteristics.
The Flipper Zero is a multifunctional hacking device that includes support for RFID (Radio Frequency Identification) and NFC (near-field communication) capabilities. These features allow the Flipper Zero to interact with and manipulate RFID and NFC devices for various purposes.
With its built-in NFC reader and writer, the Flipper Zero can read information from NFC tags, such as contactless payment cards, access cards, or NFC-enabled smartphones. It can also emulate NFC tags and act as a "virtual" NFC card, enabling it to clone or impersonate NFC tags for testing or practical applications.
