Quote:The FBI said 22-year-old Trevor Graves repeatedly hacked into the university's grading system to give himself and others higher grades and to get advanced copies of exams. Agents said the hacking happened from the spring of 2015 to last December.

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.

Law officers arrested Graves in Colorado this week.
