An immediate mitigation solution is available for a security vulnerability associated with both the key derivation algorithm used to generate MIFARE Classic® keys and the secondary encryption algorithm used to secure the underlaying card data. This vulnerability affects Saflok systems (System 6000™, Ambiance™, and Community™).

As soon as we were made aware of the vulnerability by a group of external security researchers, we initiated a comprehensive investigation and prioritized developing and rolling out a mitigation solution. With a mitigation solution available now, customer communication has been initiated.

We are unaware of any reported instances of this issue being exploited. Still, we strongly recommend all customers not already engaged in scheduled security upgrades address this vulnerability as soon as possible.
