The University of Pennsylvania was among dozens of universities worldwide that were hacked and where student and employee records were posted online this week.
Penn officials issued an e-mail Wednesday confirming the breach, which they said was limited.
"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 e-mail said.
Other universities that were hacked included Harvard, Stanford, Duke, Purdue, Rutgers, Cornell, and Johns Hopkins. The Universities of Tokyo and Cambridge were among those breached outside the United States.
