RFID Attacks

RFID uses electromagnetic fields to ID & track tags which hold electronically stored information. There are two main types of RFID: passive and active. Passive tags use energy directly from RFID readers while active tags have their own local power sources.

Common attacks against RFID are:

• Silent stealing of RFID information using an RFID reader like Proxmark3.

• RFID cloning to gain unauthorised access to specific locations.

• RFID skimming is when attackers plant a "skimmer" behind a legitimate RFID reader to steal RFID information.

• NFC amplification using amplified antenna to exfiltrate small amounts of data like passwords over relatively long distance.
