He made copies of images and videos that he found in the personal accounts without permission, and stored the data at his home.

Once he had access to the Yahoo accounts, Ruiz admitted to compromising the iCloud, Facebook, Gmail, DropBox and other online accounts of the Yahoo users in search of more private images and videos.
