I assumed a simple hack (the interface remains as it is, only the cable going in the opposite direction is cut/​blocked) rather than some more complex reingeneering of the interface. But this is an unwarranted assumption on multiple levels—the way the interface works (a simple cut of cable will block copying in one direction without raising an alarm), the technical skills of the collective (if they are qualified enough to do a simple hack and avoid detection, it is not too unlikely to assume they could do a complex hack, too).
