There are many ways,
One of the more used one seems to be sql injection thru a website, where they basically tell the sql server to create a windows user for them, where the sql server has windows command execution on. Then they log directly into the server thru RDP which is enabled on default port, like always.
Another one is social engineering, where an ex-member sells the files or a sinister guy joins the team with the plan to steal the files.

Theres many-many things. Some of them:
