There are may things someone takes i count to select a hotel to stay, the luxury, wifi connection, pool, air conditioner and many others. but something really important is that your stuff remains safe, knowing that no one can enter without your permission, including the cleaning staff.
That is why a new exploit discovered by F-Secure researchers is important, a vulnerability in a popular and widely used electronic lock system (Assa Abloy) that can be exploited to unlock every locked room in a facility
For this hack, the attacker needs access to any target hotel key, even though it isn’t from a room or it has expired. Then he would need a portable programmer with a custome code they created, it is hold near the lock to open and in a minute it will be unlocked.
The researchers, for obvious reasons didn’t released the code for the master key and, in fact, showed the findings to the affected company. With Assa, the worked for over a year to recently release an update that fixes the problem
