Raynaldo Rivera, 20, and Cody Kretsinger, 23, studied together at the University of Advanced Technology in Arizona in 2011. The two students accused of Sony Pictures hack participated in Cyber Defense Competition team exercises at the university. Both men’s grand jury indictments charge them with conspiracy and unauthorized impairment of a protected computer to participate in the Sony breach, which authorities said cost the studio more than $600,000. The attackers used a VPN service in an attempt to mask their activities, and later boasted of having compromised the Sony website.
