The thing with anonymous is that they have no membership, no offices, no spokeperson...
Basically you can blame them for everything and for nothing.
So they might not have been the one that did it but at the same time the act of leaving the file could be considered as an act of declaring membership or sympathy to their cause...
it's kinda easy and cheasy to at the same time not have membership and depending on actions claims responsability or not on what random people are doing, depending on whether you like people reaction to it or not...
And in the unlikely event that they actually did it they would never acknowledge it because the person doing the acknowledgement could be prosecuted by a federal court( or at least would be considered a person of interest in the investigation).( you can't prosecute an organization that doesn't exist but you can prosecute individual people).
