Hi Hannan

There is no circumstance that tomcat user should be running the sshd
command.  It could be this machine has been compromised.  Unless you have
some strange setup that you are logging in as tomcat user.

Please contact me directly if you want me to check.

Meanwhile you might want to have a look in /tmp directory and tomcat8 home
directory to see if there are any strange files there:

ls -ls /tmp

You might find that there is a rogue sshd program that has been installed
there.  Note that if you are running a very old war file your risk of
compromise is very high.

Bob
