I've recently been awarded the pleasure of overseeing the technology upgrade of an HVAC control system from #iLON over to the #BACnet protocol in a large scale building.
Any one in the fediverse have any experiance dealing with the security (or lack there of) in the open protocol. from a quick search I find a few metasploit payloads available, but it seem like there is such low hanging fruit there is no need to exploit. just plug in and own the system.

Am I crazy? (rhetorical question, I am)
