Imagine you’re a secret agent, and you’ve just discovered that the bad guys have a copy of your secrets decoder ring. Not such great news, right? That’s basically what happened to Siemens late last year. A bunch of hackers managed to get their hands on the global private keys for some of Siemens’ industrial devices – and that was quite bad PR, to say the least. If you’re wondering what a private key is, think of it as the secret handshake that lets your devices know you’re one of the good guys.
