as long as you follow the herd (for example, disable password ssh login, only allow ssh key login, use something mind numbingly boring like debian stable, set up unattended updates, update and reboot every night, etc, don't use any exotic packages etc) I suspect you are simply not a worthwhile target even with LLM agents as opposed to humans

Until your VPS provider has its management dashboard breached, allowing an attacker remote console and configuration access to your VMs and everything that enables.
