You always will. Welcome to the Internet. The difference is whether or not you’ve taken steps to secure your stuff. You need to understand what this malware is looking for. It’s explicitly looking for unsecured services. Such as WordPress, SQL, etc. There are inexperienced users out there that inadvertently expose themselves. I see this type of probing at work and at home. Don’t overly stress it. My home server has been running for a decade without issues. Just keep it updated and read before you make any changes if you don’t fully understand the implications.
My home based server is behind a pfsense firewall. Runs Arch. Everything is in a non-root docker container. SELinux is enforced. All domains are routed through Cloudflare. Some use Cloudflare Zero Trust.
