The University of Pennsylvania was among dozens of universities worldwide that were hacked and had student and employee records posted online this week.
Penn officials issued an email Wednesday confirming the breach, which they said was limited in scope.
"Fortunately, no sensitive information that could result in identify theft, such as Social Security numbers, PennKey passwords, bank account numbers or credit card numbers are contained in the database that was compromised," the email said.
Other universities that were hacked include Harvard, Stanford, Duke, Purdue, Rutgers, Cornell, and Johns Hopkins. The University of Tokyo and Cambridge were among the those breached outside the United States.
