Security Challenges and Attack Vectors in Modern Steganography

Steganography, the ancient art of concealing information within innocuous carriers, has evolved into a sophisticated discipline at the intersection of cybersecurity, digital media, and data privacy. This comprehensive review explores the progression of steganographic techniques from historical ciphers to modern digital embedding methods, emphasizing its critical role as an invisible shield for data protection in the digital age. The paper categorizes and examines the primary types of steganography such as text, image, audio, video, and network-based highlighting their methodologies, strengths, and applications. A detailed literature review presents key advancements, current trends, and influential research contributions in the field. Furthermore, the paper evaluates quality metrics used to assess steganographic performance, including imperceptibility, capacity, and robustness. Security challenges and attack vectors such as steganalysis and active adversarial threats are discussed to underscore the ongoing arms race between steganographic methods and detection techniques. Recognizing the importance of empirical research, the review also catalogs widely used datasets tailored to various steganographic domains. The paper concludes by identifying current limitations and proposing future research directions aimed at enhancing security, adaptability, and real-world deployment of steganographic systems. This review serves as a foundational reference for researchers, practitioners, and students seeking to understand and advance the field of steganography
