Steganography: The Art and Science of Hiding Things in Other Things – Part 2
Summary
This article, the second part of a series, delves into the art and science of steganography, specifically focusing on the methods of hiding data within images. It builds upon the foundational concepts introduced in the first part regarding how digital bits constitute image data and their implications for concealing information.
IFF Assessment
Steganography is a technique used by adversaries to hide malicious payloads or communications within seemingly innocuous files, making detection more challenging for defenders.
Defender Context
Understanding steganography is crucial for defenders as it represents a sophisticated method for exfiltrating data or embedding malware, often bypassing traditional signature-based detection systems. Defenders should be aware of tools and techniques that can embed data in various file formats and look for unusual file sizes or metadata anomalies.
