IoTGoat
IoTGoat is a deliberately insecure firmware created to educate software developers and security professionals with testing commonly found vulnerabilities in IoT devices.
On a related note, check out IoTGoat - it's a deliberately insecure IoT firmware image based on OpenWRT that you can use to explore a lot of common design flaws in embedded Linux devices: https://github.com/OWASP/IoTGoat

All in all, I'm quite happy with it. SmartSet is much more accessible than most of the custom stuff I have around (actually my favorite custom firmware thus far is the very underrated EasyAVR).

Project mention: What should I do if I want to run timers on microseconds instead of the default milliseconds? | /r/raspberrypipico | 2022-10-17
-
Project mention: Upgrading firmware on an i3 Mega using Cura and a USB cable? The screen is unchanged. | /r/anycubic | 2023-05-02
Then I tried the same method with a different firmware from GitHub which is Marlin 1.1.9. This correctly displays I send M115. But the screen is still unchanged.

Project mention: Pimping my Casio with Oddly Specific Objects' alternate motherboard and firmware | news.ycombinator.com | 2022-10-15
Motherboard is sort of a misnomer. There are no other boards being plugged into it. That said, it's a pretty cool project. Nothing beats the good watch[1], though.
