The hacker, possibly from overseas, gained access Sept. 24-29 to a university server containing Social Security numbers, names and dates of birth, but it was unclear if the intruder stole any information, The (Jacksonville) Florida Times-Union reported.
Potential victims of the data breach attack weren't told until Friday when the extent of the attack became clear to investigators, university spokeswoman Joanna Norris said.
The university has shut down the compromised server and has taken other precautions to prevent future incidents, she said.
"Unfortunately, we are in a day and age where this is something that happens," Norris said. "I've had it happen to me."
That was little comfort to those whose data was compromised.
"I figured they would have better security," UNF student Joshua Brannock said.
He hasn't noticed anything unusual in his records but remains a little nervous despite the notification and the university's corrective measures, Brannock said.
