I guess this would most often happen through supply chain attacks or physical access, the first not being all that common in my understanding and the latter not being a typical threat model for a home computer.

The attacker would require access to your network which would likely mean they’re inside your house so you have other problems besides privilege escalation. permalink fedilink source parent
