From Cryptography to Steganography: Detecting Hidden Data in the Digital World

Steganography is a method used to conceal information, while steganalysis focuses on detecting hidden data. In today's digital landscape, steganography is often used across open communication channels, embedding files, videos, messages, and images within other files to obscure their content from unintended viewers. However, cybercriminals exploit these techniques to covertly transmit data to various devices. Traditional endpoint antimalware tools are not typically designed to search for hidden data, making the detection of steganographic content challenging. The ease with which cybercriminals can transmit data using this method highlights its potential threat. This paper reviews various steganalysis tools and explores the integration of antivirus programs for real-time detection to enhance data confidentiality. A proof-of-concept for one of the steganalysis tools is also provided.
