Hack the Jura coffee maker for fun and profit

The Jura F90 has an Internet connectivity kit that allows you to change settings via the Internet. The coolest thing? There’s a huge hole in the software that lets almost anyone login to the coffeemaker and blow out most of the settings, resulting in bad coffee, puddles, and endless service alerts.

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.

The coffeemaker can also allow hackers access to the XP machine its running on. So basically this thing is not just insecure but it can actually piss you off by allowing hackers in before you’ve had your morning coffee.
