'/etc/.a/kernelupd /etc/.a/.cf --daemonized' Using 100% CPU

I found this process which uses all CPU Power:

/etc/.a/kernel upc /etc/.a/.cf --daemonized

I have not started this myself, what is this?

It seems to be a kernel update, but as I said. I did not start this. Maybe this is caused by canonical live update?

This seems to be an XMR mining malware. My server was also hacked to run the same program, which has exactly the same file creation date time as yours.
