    That is almost certainly a malware process falsely claiming to be Bash, probably crypto mining. I can see you rebooted about 90 minutes ago. If this was on my laptop, I would shut down immediately, and reboot from my Live DVD to investigate. Feb 9, 2022 at 9:18

This is a malware process falsely claiming to be Bash. I find a ‍‍test directory in /tmp that has a bash script to running unknown scripts. I remove this script and the process don't run again. I don't know how this malware access the server. I will reinstall OS.
