Given the fact their CEO is former USAF OIS and has handled this event magnificently using ethics and morals as a guide I seriously doubt they’re hiding anything. They discovered the biggest cyber espionage campaign in the 21st century. And took a few punches to the gut in the process. They are setting a model disclosure example. Unlike the other compromised organizations that won’t admit a damn thing until they’re seated in front a legislative board of inquiry or grand jury.
