Install rkhunter from your distribution's packages (dnf install rkhunter from EPEL on AlmaLinux, Rocky Linux and CloudLinux, or apt install rkhunter on Debian and Ubuntu). Then update its data files with rkhunter --update, record a baseline of your system files with rkhunter --propupd, and scan with rkhunter --check --sk. Set an email address for warnings and let the daily cron job run. Run --propupd again after every system update, or you will get false warnings.
