A former University of Iowa wrestler has pleaded guilty for a computer hacking scheme to cheat on grades.
Federal prosecutors said 20-year-old Trevor Graves admitted to repeatedly hacking into the university's grading system to give himself and five other students higher grades and to get advanced copies of exams. Prosecutors said the hacking happened from March 2015 to November 2016.
The FBI said Graves secretly installed devices known as keyloggers in university classroom computers. That allowed him to record what his instructors typed, including user names and passwords.
The University said it spent nearly $68,000 investigating and responding to the hacking and making updates to security because of it.
Law officers arrested Graves in Colorado in October 2017. He is scheduled for sentencing in August.
