AI-suggested

1. Immediately inventory all Sciener Kontrol Lux devices running firmware version 6.5.x within the organization to identify affected units. 2. Restrict physical and wireless access to the vicinity of these locks to prevent attackers from capturing pairing communications or attempting to exploit the reused key. 3. 4. Consider deploying additional physical security controls such as secondary locks or alarms to mitigate risk until a firmware fix is released. 5. For high-security environments, evaluate replacing affected locks with alternative products that follow robust cryptographic standards and do not reuse keys or nonces. 6. Conduct security awareness training for facility management personnel to recognize and report suspicious activity near smart locks. 7. Implement network segmentation and monitoring for any connected smart lock management systems to detect anomalous access attempts. 8. Engage with vendors and security researchers to stay informed about potential exploit developments and mitigation strategies.

Description

The AES key utilized in the pairing process between a lock using Sciener firmware and a wireless keypad is not unique, and can be reused to compromise other locks using the Sciener firmware.
