Personal records for more than 309,000 students and staff were exposed this week in a "sophisticated" database attack at the University of Maryland, the university said Wednesday.
Birth dates, Social Security numbers, names and university ID numbers were compromised for people issued with a school ID and affiliated with the university's College Park and Shady Grove campuses since 1998, the school said.

Financial, academic, health and contact information such as phone numbers were not exposed, according to a statement attributed to Wallace D. Loh, the university's president.
The cause of the breach, which happened Tuesday, is unknown and an investigation is underway by federal and state law enforcement, Loh wrote. The school has 37,000 active students.
"Computer forensic investigators are examining the breached files and logs to determine how our sophisticated, multi-layered security defenses were bypassed," he wrote. "Further, we are initiating steps to ensure there is no repeat of this breach."
Personal records are valuable to cybercriminals, who can compile dossiers on victims for the purposes of financial fraud, such as opening bank accounts or taking out loans. The data may also be valuable for other types of targeted attacks, such as spear phishing.
The incident is the latest in a string of breaches that have affected companies and organizations, including the retailer Target and Neiman Marcus. The attacks against those companies focused on intercepting payment card details from point-of-sale devices.
The university said a specific database of records maintained by its IT division containing 309,079 records was accessed on Tuesday. Loh wrote the university recently doubled the number of IT security engineers and analysts as universities have been increasingly targeted.
"Obviously, we need to do more and better, and we will," he wrote.
Those affected are being contacted. The university is offering a year of free credit monitoring and advised people to be careful when sharing their personal information.
