Unless you see your server actually doing these things, I wouldn’t worry.

They are scanning your server for vulnerabilities. This happens all day, every day, and the longer you watch the logs, you’ll see this behavior more and more. The easiest option is to block them at the firewall. (ufw deny from THEIR_IP to any)
