For example I don’t know if a cheap mini PC like the GMKtec G5 would be more likely to have firmware/driver related security flaws over a more standard PC like an older Dell Optiplex from Staples.
Maybe there is something else entirely I am overlooking. I’m not sure. Most of the complaints I’ve heard are in regards to mini PCs containing bloat and potentially malicious things installed.
Everyone in this thread focusing on malware put inside the BIOS by the manufacturer.
But the more realistic issue is just a hopelessly outdated BIOS with known vulnerabilities that won’t ever get an update.
