A group of savvy hackers has found a way to compromise one of the more popular hotel room lock systems, Vision by VingCard. The Swedish manufactured system is used in 42,000 properties in 166 countries. Zack Whittaker reports at ZDNet:
These electronic lock systems are commonplace in hotels, used by staff to provide granular controls over where a person can go in a hotel — such as their room — and even restricting the floor that the elevator stops at. And these keys can be wiped and reused when guests check-out.
It turns out these key cards aren’t as secure as first thought.
F-Secure’s Tomi Tuominen and Timo Hirvonen, who carried out the work, said they could create a master key “basically out of thin air.”
Any key card will do. Even old and expired, or discarded keys retain enough residual data to be used in the attack. Using a handheld device running custom software, the researchers can steal data off of a key card — either using wireless radio-frequency identification (RFID) or the magnetic stripe. That device then manipulates the stolen key data, which identifies the hotel, to produce an access token with the highest level of privileges, effectively serving as a master key to every room in the building.
