The idea is to: Enable the Jura Impressa F90 to communicate with the Internet, via a PC. Download parameters to configure your espresso machine to your own personal taste. If there's a problem, the engineers can run diagnostic tests and advise on the solution without your machine ever leaving the kitchen. Guess what - it can not be patched as far as I can tell ;) It also has a few software vulnerabilities. Fun things you can do with a Jura coffee maker:

  1. Change the preset coffee settings (make weak or strong coffee)
  2. Change the amount of water per cup (say 300ml for a short black) and make a puddle
  3. Break it by engineering settings that are not compatible (and making it require a service) The connectivity kit uses the connectivity of the PC it is running on to connect the coffee machine to the internet. This allows a remote coffee machine engineer to diagnose any problems and to remotely do a preliminary service. Best yet, the software allows a remote attacker to gain access to the Windows XP system it is running on at the level of the user. Source: securityfocus.com/archive/1/493387
