--FILE--View of the KK 100 (Kingkey 100) tower where the St. Regis Shenzhen hotel is located from 75th to 100th floors in Shenzhen city, south Chinas Guangdong province, 23 November 2013. A San Francisco-based cybersecurity expert claimed he had hacked and taken control of hundreds of highly automated rooms at a five-star hotel in the southern Chinese city of Shenzhen. Jesus Molina was staying at the St Regis Shenzhen, which provides guests with an iPad and digital butler app to control features of the room including the thermostat, lights, and television. Molina said the KNX automation system the hotel used was also insecure, which made the hack easier. Joost Demarest, a spokesman for the KNX Association, said the most recent version of the standard did feature authentication and encryption and that it was essential that separate Wi-fi networks are used for the purposes of guest internet access and automation. Realising how vulnerable the system was, Molina wrote some code spoofing guest iPads so he could control the room from his laptop. After some investigation, and three room changes, Molina discovered that the network addresses of each room and device within them was sequential, allowing him to write a script to potentially control every one of the hotels more than 250 rooms.
