I can't understand why root user take huge CPU load, since there is no special processes running.

top -c

"top -c" command results

If your company has a breach response process, I would invoke that now.

Otherwise:

This looks potentially malicious, I would recommend looking at it closer in /proc.

With a root privilege shell, either via su or sudo -s, change into the directory /proc/{pid}. Changing {pid} for the pid shown by top, 30530 in this case.

There are many things to look at to get a clue about this process, here are a few:

exe : link to executable that started this process. # readlink -f exe
cmdline : command line that started this process. # cat cmdline | tr \\0 \\n
environ : environment variables in this process. # cat environ | tr \\0 \\n
fd : directory of links to open files and sockets.

Unless you can find a reason it's legitimate, I'd kill it via kill -9 {pid} and investigate as a potential breach.
