What would be the purpose of such firmware? The ESP32 is a complete SoC, the “firmware”, “OS”, and “application” are all the same binary. So yes you could write a malicious “firmware” without using undocumented commands. But what would be the point? Said firmware already has complete execution privileges on the devices already, with the ability to read any memory it wants to, by virtue of said firmware being literally all the software running on the devices, and owning all of the memory. |
