Malicious attack on worldwide IT infrastructure !!!
Craig Wright found out, that you can hack into a Jura Impressa F90 coffee machine (apparently not running java). If you have the configuration software for the machine runnning on a PC that is connected to the internet, you could remotley change, amongst others, the ratio of water to coffee.
Now here is a scenario for a denial-of-service-attack on the it admins worldwide. Imagine sysadmins worldwide without their quintuple shot espresso!
