Over 3 Million Hotel Doors Worldwide Vulnerable to Hacking

Researchers reveal a flaw in Dormakaba's Saflok locks that allows for quick unauthorized access.

Researchers have disclosed a security flaw in Dormakaba's Saflok electronic RFID locks, affecting over 3 million hotel doors worldwide.
The vulnerability, named Unsaflok, allows hackers to unlock any door within seconds using a pair of forged keycards.
Dormakaba has been informed and is working on mitigations, but as of this month, only 36% of the locks have been updated.
The exploit requires access to any keycard from the hotel and a $300 RFID read-write device.
Hotel guests can use the NFC Taginfo app to check if their room's lock is likely vulnerable based on keycard type.
