CyberRota Analysis
AI-GeneratedThe cashless payment system utilizing NFC wristbands from CasfID Servicios Tecnológicos S.L.U. is vulnerable due to the use of an insecure cryptographic algorithm, specifically in versions deployed at Resurrection Fest 2025. This weakness allows attackers to exploit the authentication mechanism, potentially leading to the cloning of wristbands and unauthorized access to users' balances, resulting in financial losses for both attendees and event organizers. Organizations using this system should prioritize remediation to mitigate the risk of impersonation and fraud.

Original NVD Description
Use of an insecure cryptographic algorithm in the cashless payment system using NFC wristbands from CasfID Servicios Tecnológicos S.L.U. (version used at Resurrection Fest 2025), which employs cards based on MIFARE Classic technology (FM11RF08S). The cryptographic weakness of the authentication algorithm allows an attacker to retrieve access keys using techniques known as Backdoored Nested Attack, read the wristband’s entire contents, and clone its credentials onto a compatible rewritable card. Exploitation of this vulnerability could enable the impersonation of other attendees, the fraudulent use of the balance associated with their wristbands, and financial losses for both the affected users and the event organizers.
