Is there a reason you sre using dhcp instead of assigning ips manually?

Dhcp is great if you don’t care about stuff, in my experiece as soon as you start caring you should do it manually

Just disable it, the “secure” in secure boot is a security for whoever needs to ship signed crap in windows or if your employer needs to spy on you. On a linux gaming laptop its perfectly useless.

I mean, any organization can have a random guy install some crap on their pc. Humans are often the weakest link, I am not a microsoft fanboy and usually despise them, but in this case it looks like they are clearly communicating and performing the right steps.

Hate them when they deserve it, because they usually do. Here nothing points to something nefarious besides the attack itself.
