There's a few issues that have been brought to light in the last couple years at Hackfest and other events related to LoRaWAN / Meshtastic (and derivatives). I think most notably was the failure in entropy generated during the flashing process, detailed here - https://nvd.nist.gov/vuln/detail/CVE-2025-52464
I think we're a bit past the initial AES issues, at least the Meshtastic project promptly alerted people to their crypto issues and encouraged everyone to update firmware asap.
It's not too hard to use, as long as the hardware is flashed and ready. For the end user, it's an app that connects to a bluetooth connection. I think it would very trivial to have a few good LoRaWAN ops in the community, flashing nodes en masse and handing them out to peers.
