Stegomalware is a type of malware that uses steganography to hinder detection Steganography is the practice of concealing a file, message, image, or video within another file, message, image, video or network traffic

Outguess is a steganographic software It has handlers for image files in the common netpbm and jpeg formats, so it can, for example, specifically alter the frequency coefficients of jpeg files It is written in c and published as free software under the terms of the old bsd license
