The Iowa Lottery issued an apology after a mistake caused sensitive data to be released.
This time data about 2,967 winners of prizes $600 or more in 2011 were provided to a professor of journalism at the Grand Valley State University in Michigan. Unknown to the professor, a hidden column contain the social security numbers of the winners. The information was posted on a website for about 10 days before someone figured how to unhide the information. The person then contacted the professor who removed the information. There is no telling if anyone had downloaded the posted data.
The lottery has contacted each of the people whose social security numbers were released. They will also spend about $30,000 to help monitor the credits of the affected people.
