CHARLESTON, Ill. — Eastern Illinois University says someone outside the school may have broken into files containing personal information from about 9,000 current and former students and applicants. The university on Friday said it found a number of viruses on a server used by the university’s admissions office that could have provided outside access. Technology workers believe someone had such access between Nov. 11 and Nov. 16. But they aren’t sure if any of the files were accessed. The server contained undergraduate electronic admissions applications submitted between March 10, 2000, and Nov. 16, 2009. University officials say they’ve mailed letters to students and applicants whose information is on the server. Copyright 2009 The Associated Press.
