In 2004, a graduate student apparently posted a class roster of 601 students, complete with names an social security numbers on the web. (“ODU Graduate Student Posts Student Information on Website, School Investigating,” via Netsec.)
Update: Lyger of Attrition pointed out that the dates in the WAVY-TV story don’t add up. There’s a story in the Virginian Pilot, ”
Social Security numbers of 601 ODU students posted to Web,” which says that the data was up for nearly two years. I suspect that the TV news site made a simple mistake.
