New Approach on Steganalysis: Reverse-Engineering based Steganography SW Analysis

Recently, steganography tools for concealing messages in images have been widely used, and internal mechanisms for hiding messages using steganography tools are mostly unknown to public. Therefore, we adopted the reverse engineering for unveiling the information hiding algorithm and operation mechanism applied to 'Steg' steganography software using IDA tool. By reversing the steganography software, we disclosed the internal steganographic mechanism used on 'Steg' software. Therefore, we can propose a new approach for efficiently detecting and automatically extracting hidden messages in stego data using the software reversing technique.
