A Texas A&M graduate faces prison time for the computer breach earlier this year that compromised the information of thousands of students and staff.
Luis Castillo was convicted Wednesday in Houston federal court of gaining unauthorized access to A&M's domain controller.
University officials first noticed the domain controller, code named "Ajax", was hacked numerous times.
Federal agents later learned Castillo hacked the computer system capturing the Net IDs and passwords of 133,000 students and university employees.
To date, no misuse of the captured information has been reported.
The university incurred more than $67,000 in losses trying to protect students and staff in the aftermath.
Castillo will be sentenced December 10. He faces up to five years in federal prison and a $250,000 fine.
