A data breach at Harvard University appears to have exposed system and email passwords belonging to an unspecified number of faculty, staff, and students from numerous schools. The university discovered the intrusion on June 19 but publicly disclosed it only Thursday while it worked to mitigate the issue. This is the second time in recent months that Harvard has had to deal with an intrusion into its networks. In April, a group of hackers claimed a pro- Palestinian agenda defaced the website of Harvards Institute of Politics.”]
