That last bit is absolutely infuriating. Medical device manufacturers are cranking out insecure devices that rely on security through obscurity. No, I don't think people should be using Flipper Zeros to hack someone else's insulin pump. It's also unforgivable that someone should make an insulin pump that another can hack with a Flipper Zero.

I use netcat for legitimate things every day. If someone made an IP server that I could hack with netcat, they should be ashamed of themselves. It's not netcat's fault that their security sucks. Well, same with Flipper Zero.
