Even a basically honest employee (or, in this case, the Ph.D. candidate and company intern, Julia) can sometimes be bribed or deceived into revealing information of crucial importance to a social engineering attack, such as where the target computer system is located and—the key to the success of this attack—when they were going to build the new release of the software for distribution. That's important, since a change of this kind made too early has a higher chance of being detected or being nullified if the operating system is rebuilt from a clean source.
