We have a website running on an custom Ubuntu server managed and hosted by the client himself, since last two days the website database is getting hacked and someone deletes all the db tables from the database.
Upon checking the Db connection I come to know that database is getting connected with any username and password, is there any configuration issue in mysql? I am not able to find anything on google or stackoverflow.
Any help would be appreciated. TIA.
EDIT: I checked mysql users table and there are three users in the table as listed below,
