Occasionally I see the server CPU is 100% higher all the time. Here is a screenshot from later:

top

Oracle user 193 CPU % command SSH

Imitation of SSH

find / – name ssh

The config. Json

The CPU usage recovers

So make your username and password a little bit more complicated

Let alone the Internet.
