The second data compromise involved a server at the Technology Transfer Department, which is part of the University's Innovation Center. FBI officials told the university about that breach on April 21. The server, which contained patent data and intellectual property files, was apparently involved in another incident that the FBI was investigating, Sams said, without providing any further details. The university had no idea that the server had been broken into until the FBI pointed it out, he said.

The FBI is currently investigating both incidents, he said.

Ohio University today started sending out e-mails to those affected by the hack into the alumni database server. "We are sending them at the rate of 10,000 an hour," Sams said. He added that the University has also set up a Web site providing details about the incident and instructing affected individuals on the steps they can take to mitigate the risk of ID theft.
