Lincoln College in Lincoln, Ill., will close its doors following a ransomware attack in December, according to an announcement on the college's website. The decision marks the first higher education institution closure in the U.S. due in part to a cyber attack, as colleges and universities grapple with an increase in ransomware attacks during the COVID-19 pandemic. The website said officials recently notified the Illinois Department of Higher Education and Higher Learning Commission of its permanent closure, effective Friday.
