Human hacker maybe not, but AI scanning, finding vulnerabilities which is next writing and executing new created code - yes.
This is automated way to find and exploit PCs in Internet as zombies for DDoS attacks or other activities, like scanning deeper the LAN server lives in.
It's not year 2000 anymore
Other thing is that unprotected server is a subject to inject any malicious code when connecting to it freely without any antimalware scanner up and running
That's why I use NGFW that scans data in motion - on the fly - with WAF, IPS & antimalware, so malicious user won't do SQL injection, cross-site scripting (XSS), and code injection through user input fields.
