Nfc Wristbands
Monthly
Weak cryptography in CasfID NFC wristbands allows attackers with physical access to clone credentials and impersonate attendees. The wristbands use MIFARE Classic technology (FM11RF08S) vulnerable to the Backdoored Nested Attack, enabling full readout and cloning of wallet data. No active exploitation is confirmed, but the attack technique is well-documented and can lead to financial fraud at events.
