Finding out who has modified a Stored Procedure on SQL Server?

Question

Looks like somebody has logged in and modified a Stored Procedure on our SQL Server database. Is there a way to find out the credentials of the person that has done that?

You can look at the default trace and figure this out easily. Try the examples from Jonathan Kehayias.

This is to show as an example and you need to look at the ALTER OBJECT event type.
