"A hacker broke into a computer server at the University of Colorado
College of Arts and Sciences� Academic Advising Center, exposing the
names and Social Security numbers of nearly 45,000 students, officials
said Tuesday.
University officials were sending letters notifying students
enrolled at CU-Boulder from 2002 until the present that their
information was compromised.
Computer security investigators on May 12 discovered a worm
had entered the server through a vulnerability in its antivirus
software, which had not been properly patched by Arts and Sciences
Advising Center�s IT staff, according to a CU statement."
