This is an interesting article. It outlines a known vulnerability with a common hotel card lock system. To their credit the manufacturer has quickly released a patch to fix the issue. The question is, will hotels actually deploy the patch in a timely manner? Or worse will they ever deploy the patch?
Have you checked all your devices (printers, access points, switches, etc) recently to see if patches are required? Every company and home should regularly check if their equipment needs these updates.
