Good evening friends.
Happening right now. The server is down.
The server has a problem. looks like a virus. commands are regularly launched from the root ls, top, bash, pwm and so on. . After I kill them, they reappear after a few seconds and load the processor so that the site does not work.
Run from root. example htop joxi.ru/MAj1yX8i4j9ld2 Changed the
password immediately.
Tell me what can be done.
Thanks in advance.
