So, I’m trying to setup a honeypot with a old laptop running Ubuntu. I’m also considering giving away root privileges to some default name accounts, I know that it’s possible to mess up the OS installation and file system, but I’m not worried with that. I’m concerned that there is a way to really screw up my laptop hardware with root privileges. I have some candidates like /dev/sys/firmware, cpu microcode, overvoltage, but not knowing for sure if that can be done (not really a thing I can test eh?), I figured that this is the place to ask these kind of questions.
So, how can someone really mess up a computer with Linux and root privileges?
Edit: Just to clarify, I know it’s possible to destroy the installation with dd, but like I said above, I’m not worried with that, I’m concerned with physically bricking the laptop’s hardware.
Edit 2: It’s only considering a remote connection like ssh, so no physical access to the machine therefore, no thermite
