Issue /etc/passwd changed during this night?

[tds]

Hi to all, I set zabbix to notice me every kind of issue coming from plesk.
This night I received an e-mail who notifies me that "/etc/passwd" has been changed without anyone really changing that file.
I'm in trouble or not?

 

[tds]

P.S. I seen that next row has been added to that file:
plesk-ssh-terminal:x:987:986lesk SSH Terminal:/usr/local/psa/var/modules/ssh-terminal:/usr/sbin/nologin

What could it be?

Looks like the line is added for use of the Plesk SSH terminal extension which is being enabled by default since Plesk 18.0.38.

So I don't need to worry?
