Ralph Langner provides the most detailed presentation of the Stuxnet S7 code. He goes through the key Function Codes and Data Blocks in detail and shows how it matches to the Natanz facility. You see Ralph's teams comments throughout the Stuxnet code, and the level of detailed analysis.

This performance from S4x12 is a great example of the technical detail we look for in a Stage 2: Technical Deep Dive Session. The beauty of Ralph's presentation is he also makes the key points understandable for a less technical viewer.
