Backdoor risk for QOTOM Mini PC?

Hi all… was looking to build a pfsense on QOTOM Mini PC
What is the risk of this mini pc being backdoored? I’m thinking with a fresh sw install the only backdoors I need to worry about is hw.
Thanks in advance!

Not very likely but not completely impossible


Appreciate the reply! Thanks!

LOL I have three similar boxes ! I’d say there is a “risk” with all hardware though in this situation unless someone with expertise inspects the units you’ll never have any idea.

I’m naive I guess
Attempted some level of due diligence… couldn’t find any hardware vulnerabilities on cvedetails, reddit,etc… so posted here. Eh all good
