The U.S. Secret Service and cyber security expert MITRE Corp. are working with the University of Maryland over last week's data breach, university officials said Friday.
In an open letter to students, employees, faculty and alumni, university officials said they have been working "around the clock" to make sure their data systems are protected after losing the personal information of more than 300,000 current and former students, staff and faculty.
Hackers had access to the information early Tuesday. The university said thieves stole names, Social Security numbers, birth dates and the university identification numbers of 309,079 people affiliated with campuses at College Park and Shady Grove since 1998. The university said no financial, academic, health or contact information was stolen in the breach.
