In September Juliano Rizzo and Thai Duong unveiled their latest masterpiece: A padding oracle attack on the crypto implementation of the ASP.net framework allowed them to download any file. Their original presentation did not fully unveil how to practically implement the attack. This hands-on presentation is the result of our notes and experience in developing a reliable exploit for the padding oracle attack against ASP.net. It takes you from a simple CAPTCHA crack to a fully optimized padding oracle attack against ASP.net that bypasses all typical workarounds.
