Rqst'ing help identifying type of attack


Greetings,
Just logged a brute force attack on our server, but something strange shows up - the Plesk Database appears to be accessed and a query for root password takes place. Here's a few lines from the log - a couple of attempts at guessing the root password, then the strange database access. Can anybody tell me what's going on here, and how the database was accessed via plesk sshd? Thanks in advance.

uuuhhhhh, never mind - it turned out to be my server provider's tech support (I didn't recognize the IP ...). I had provided them with the admin pwd and they were already logged in as admin at that point, thus the ability to run the DB query ...
