Researchers Uncover Security Flaws in Millions of Hotel Room Keycard Locks
-
Researchers discovered vulnerabilities in Saflok keycard locks used in 3 million hotel rooms globally, allowing them to open any door in seconds.
-
The hack involves exploiting weaknesses in MIFARE Classic RFID technology and Dormakaba's encryption to spoof master keys.
-
Dormakaba has worked on fixes since 2022 but only 36% of locks have been updated so far. Full fix will take months or years.
-
Guests can check if their lock is vulnerable using an NFC app to see if keycard uses outdated MIFARE Classic.
-
Researchers took care in revealing details to avoid enabling thieves, unlike previous hotel lock hack revelations.
