Ruiz admitted to targeting accounts belonging to younger women -- including his personal (and hopefully former) friends and colleagues. Once he had access to their Yahoo accounts, he used password resets on third-party sites to break into Apple iCloud, Facebook, Gmail, DropBox and other accounts.

According to ZDNet, Ruiz worked for Yahoo (which has the same parent company as Engadget) for more than ten years. During that time he held multiple roles, including reliability engineer for Yahoo! Mail. He currently works at another tech company that specializes in single sign-on solutions. Ruiz will be sentenced on February 3rd and could face up to five years in prison.
