i guess you can install htop (like task manager) and check what proccess is using resources and kill it.
if you are on debian/ubuntu command is

apt install htop

Hey friend!

At the “top” screen press C and watch that name change. I’ll bet the filename of the process looks like someone just smashed their keyboard to name it. I would submit the probability that your server has been compromised, and that this task is masking it’s true nature. The C button will unmask it a bit, typically.

It’s running as root too, so you can’t really save this machine and know you’re safe. You should prepare your backups to create a new droplet, and use this one to investigate how it was compromised. If you find the filename of the running application, you can use the “stat” command to grab some vitals, like this:

stat /path/to/file

The time/date in which it was created will often correlate to a log entry for a running service on the system, allowing you to track it’s origin. I know that’s a bit vague, but that’s because there is no one path to this, it’s very dynamic.
