Up to 1,200 students, faculty and staff at Webster State University (WSU) in Utah might have had personal information compromised earlier this year and the man suspected of the breach has been nabbed.

Joseph W. Langford was arrested and charged for burglary in connection with the case, according to the Deseret News. A WSU spokeswoman confirmed that Langford hacked into a university computer, likely looking for test materials. She also indicated that personal and financial information wasn’t likely compromised, but the university is still taking precautions.

Campus police began reviewing security footage after a faculty member noticed “unusual activity” on a computer. They found that Langford broke into a lab to gain access to the affected computers.

WSU mailed letters to potential victims recommending that they change their passwords. It is unclear whether Langford is still enrolled as a student.
