Former Iowa wrestler Trevor Graves appeared in federal court in Davenport on Monday and pleaded guilty to transmission of a command to damage a protected computer.

Graves was arrested in Denver in October 2017 and appeared in an Iowa court the next month. The charge of transmission of a command to damage a protected computer means Graves faces up to 10 years in prison.

According to a plea agreement, Graves intentionally “caused the transmission of a command that caused damage and impairment to the integrity or availability of certain data, program, system or information” to the Iowa Courses Online system from March 7, 2015, to Nov. 15, 2016. Graves obtained professors’ usernames and passwords via a key logger and used the information to change grades for him and five other students.

The IT costs for security remedies and breach discovery totaled approximately $67,900.

Graves is scheduled for a sentencing hearing in Davenport on Aug. 23.
