There was something on Reddit about a MS security hole that could have been exploited prior to patch that would give them root access, which is how they were able to take over every computer at the site. I'm not really familiar with how to navigate Reddit, or the legitimacy of the claim, but they claimed that the financial docs alone would be devastating to the company, and some of the password docs are really stupid as the password to access them are in the name of the file...
