Replay Attacks







Risk Rating:


This attack is performed by capturing the session from the tag to reader and can be simply replayed to gain access or to perform other deeds. This attack can be combined with the eavesdropping attacks to capture data. Essentially, the captured session is replayed through software—even over long distances. If an attacker could capture a badge at a remote location and the second attacker could stand in front of the target reader in real-time, the RFID contents may be sent transparently to the reader, thus allowing access.
