Hacking Hotel Infrared Systems
A vulnerability in many hotel television infrared systems can allow a hacker to obtain guests’ names and their room numbers from the billing system.
It can also let someone read the e-mail of guests who use web mail through the TV, putting business travelers at risk of corporate espionage. And it can allow an intruder to add or delete charges on a hotel guest’s bill or watch pornographic films and other premium content on their hotel TV without paying for it….
“No one thinks about the security risks of infrared because they think it’s used for minor things like garage doors and TV remotes,” Laurie said. “But infrared uses really simple codes, and they don’t put any kind of authentication (in it)…. If the system was designed properly, I shouldn’t be able to do what I can do.”
