Michael T. Raggo , Steganography, Steganalysis and Cryptanalysis
This presentation will present Steganography and techniques for Steganalysis (identifying files with hidden messages). A review of Steganography will provide the basis for identifying and dissecting carrier files. There will also be a demonstration of carrier file analysis and disection. There will also be a demo of my new Steganography detection program, StegSpy. Cracking and reverse-engineering Steganography programs will also be covered. A cryptanalysis case study will review the steps necessary to reverse engineer and reveal a hidden message. Additionally, other steganalysis and password cracking tools will be highlighted.
