This paper focuses on the study of steganoprahy as an anti-forensic method. The purpose of steganography techniques is to hide information from individuals unrelated to its content.  Through a systematic review, the objectives of this article are: (I) explore and investigate the importance of steganography in computer forensics; (II) understand and analyze the methodology used to hide information in a file and (III) understand and analyze the methodology used to extract the information. The results summarize the previous research on this topics and we conclude the article with a warning to develpop more studies regarding this thematic as well as and make the security forces aware of this type of digital evidence and, in the same way that the methodology is being developed, the stegananalysis must also seek, at least, to reach the same technological level
