If you own a Jura F90 Coffee Maker, you can also buy a Jura Internet Connection Kit, which lets you program and set your coffee prefs via the network: however, its got a bunch of vulnerabilities that allow for remote denial-of-coffee attacks:
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)(via /.)
