High CPU LOAD

[karmad]

Hi,

We have a service that is using more than 300% of the cpu,

when we kill it, it comes back with a different name

Any ideas what this can be?

Thank you

What service exactly?

What does "300% of CPU" mean exactly?

[karmad]

The command names changes whenever we kill it,

suvzxlizlh - using 391 of the CPU

That probably means that your system has been hacked and is part of a botnet, or is bitcoin mining.

In these cases we usually recommend backing up your system to an outside device or drive, and formatting and reinstalling your server.

Also, once you have your system back up, be sure you enable the firewall.
