During a search I received a link to an Excel spreadsheet on your domain. I was able to open it with no security prompts and see personal information for over 100 survey recipients. The file is located under the http://cuip.uchicago.edu/~stuart/ folder, which is also completely open to the public as a browsable directory structure. I was also able to determine that others folders under your domain are completely open and browsable. I\'d suggest you take your security more seriously as this is a hack and/or significant data breach just waiting to happen.
