How to tell if MySQL was hacked

Hello,

We have a website with apps/DBs running on mySQL.  User feels one of the DBs may have been hacked and certain words put into a table.

Is there a log we can review with activity or a way to tell if this is old or recent?

Thanks

Hi btny,

you should have a backup and then you could find differncies. This could also a way to check if you have been hacked. Another way doesn't exists, because mySql doesn't save any connection.

Kind regards,
Henning

Thanks for your input.
