A group of hackers calling themselves Team GhostShell is apparently intent on exposing the vulnerabilities of higher education institutions, according to a Pennsylvania newspaper. The hackers have already posted private information from the University of Pennsylvania and other universities spanning the globe.

Data from 1,764 University of Pennsylvania students and administrators has since been removed from the Internet. The information included names, email addresses, phone numbers and student ID numbers of students, alumni, faculty and administrators. But no sensitive data that could lead to ID theft was included in the hack, the university said.

According to The Daily Pennsylvanian, other universities that were targeted by the hackers include Harvard, Princeton, Stanford and Johns Hopkins universities in the U.S., and the University of Edinburgh, University of Berlin and Osaka University abroad. A total of 100 universities were targeted, said the newspaper.

News network Examiner.Com also reported that other universities involved include the University of Michigan, Tokyo University, New York University, University of Rome, University of Florida and the University of Zurich.
