Mississippi State University officials are investigating a possible security breach after a computer hacker claimed to break into school computers.
The hacker claims to have access to the user-names, actual names and passwords of 929 students.
A Mississippi State spokesman said steps are being taken to protect the university.
The university reported in a release that no secure data was breached.
It also said the hacker was based in Brazil.
"Cyber-crimes and 'hacking' plague Fortune 500 companies, the federal government, and unfortunately is a reality in higher education as well," said MSU President Mark Keenum.
