Security Breach at Dormakaba Saflok Locks and Immediate Actions to Take with Ultralight C Chips.

The Unsaflok incident involved a breach where unauthorized individuals exploited weaknesses in the encryption methods used by hotel cards at Dormakaba Saflok lock systems.. This breach not only jeopardized the security of properties globally but also undermined guests’ confidence in the privacy and safety of their accommodations.

The saga of the Unsaflok Situation commenced with what seemed like a software update deployed across prestigious hotel chains globally. This update aimed to enhance the functionality and security of the hotels key card access systems. However unbeknownst to both the developers and the hotels a sophisticated vulnerability had been deliberately inserted into the code of this update. This vulnerability was not an oversight. This is a calculated move by cybercriminals with an agenda to exploit the prevailing trust in the Saflok hotel lock system.

The cybercriminals had engineered this vulnerability to enable them to generate master keys using an algorithm that replicated encoding procedures. These master keys granted access to any door within hotels utilizing the Saflok system, without leaving any evidence of intrusion.

Immediate Actions for Hotels

Following this incident, there are steps that hotels can and should implement to protect against similar vulnerabilities;

  • Security Assessment: Carry out a thorough assessment of existing key card systems to pinpoint any potential vulnerabilities.
  • Software Upgrades: Ensure that all software linked to card encoding and management is kept current, with the security updates.
  • Staff Training: Improve staff training regarding security procedures, such as handling cards and recognizing behavior.
  • Guest Communication: Maintain communication with guests about the security measures in place and how they can help create a safer environment.

Long-term Security Improvements

In addition to steps, hotels should focus on long-term security enhancements;

  • Advanced Encryption Technologies: Use encryption technologies for key cards to enhance protection against hacking.
  • Multi-factor Authentication: Consider using authentication methods like combining cards with PIN codes or biometric verification for sensitive areas.
  • Regular Security Assessments: Implement security assessments and updates to proactively address threats.
  • Partnerships with Security Experts: Collaborate with cybersecurity firms to stay informed about emerging threats and security advancements.

In response to the Unsaflok Situation and the broader need for enhanced security in the hospitality sector, one significant action taken by many hotels was the migration from MIFARE Classic 1K chips to MIFARE Ultralight C chips in their key card systems. This migration represents a shift towards more secure technology that better protects against unauthorized access and cloning, addressing vulnerabilities highlighted by incidents like Unsaflok.

Understanding MIFARE Classic 1K Chips

MIFARE Classic 1K chips have been widely used in various applications, including hotel key cards, public transportation tickets, and access control systems. They operate at 13.56 MHz frequency and provide 1KB of data storage. While these chips were considered secure at the time of their introduction, advances in technology and cryptographic analysis have exposed vulnerabilities. Specifically, weaknesses in their encryption method (Crypto1) made it possible for hackers with modest resources to clone cards and gain unauthorized access.

Advantages of MIFARE Ultralight C Chips

MIFARE Ultralight C chips are designed with advanced security features to overcome the limitations of the Classic 1K chips. Here are some of the key advantages:

  • Advanced Encryption Standard (AES) Support: Ultralight C chips utilize AES encryption, a significant upgrade from the Crypto1 algorithm used in Classic 1K chips. AES is a more robust encryption standard that provides a higher level of security against cloning and unauthorized access.
  • Tamper Protection: These chips include mechanisms to detect and counteract tampering attempts, making it difficult for unauthorized individuals to alter the chip’s functionality or access its data.
  • Cost-Effective Security: Despite their advanced security features, Ultralight C chips are designed to be cost-effective for widespread deployment in sectors like hospitality, where large volumes of key cards are issued and managed.
  • Compatibility and Integration: MIFARE Ultralight C chips are compatible with existing NFC (Near Field Communication) infrastructure, making it easier for hotels to upgrade their systems without significant investment in new reading hardware.
