Steganography is the process of hiding information, images, or audio messages inside another piece of information, image, or audio. The most common method is by embedding information into digital images. Learn more the various techniques used Usually when organizer gave us Image, Music, Video, Zip, EXE, File System, PDF and other files, it a steganography or forensics challenge. Run file command first. Metadata is important. Checkout the EXIF data of the file by using exiftool [filename] command. Try issuing binwalk [filename] on the file. They may hide another file in the file When an image file is used as the cover medium, it is known as Image steganography. There are a number of techniques employed to hide secret information within an image file but one of the most common technique is known as the Least Significant Bit (LSB). Every byte of an image pixel is made up of 8 bits Understanding how to hide data in an image using steganography, and prevent that data from being corrupted, can prove very helpful for both attack and defense, including forensics. Check out the series of articles to learn image steganography algorithms and techniques, or download free, open-source steganography software in Python from Github
Steganography is useful in situations where sending encrypted messages might raise suspicion, such as in countries where free speech is suppressed. It's also frequently used as a digital watermark to find when images or audio files are stolen. And on a less practical note — it's just cool. More Info: A Beginner's Guide to Steganography Image Steganography is a method of hiding secret data in the image. The main motive of steganography is to hide intended information within any image. Predicting House Prices with Regression Blood Donation Management Syste Palette-based image steganography is basically another sub-type of LSB steganography, in which the communicated data is encoded into least significant bits of the image palette rather than into those of the carrier. The obvious downside to this method is its low data carrying capacity. Use of service fields in data formats Digital steganography is a method of concealing a file, message, image or video within another file, message, image or video. The technique is used by a piece of malware popularly known as Stegoloader (or W32/Gatak), a trojan or downloader for stealing data and delivering ransomware. Lordian Mosuela describes how the malware succesfully uses steganography to hide in image files Steganography, the study of data hiding with the intent of sending a secret message, has become increasingly important over the last few years as the use of digital media, which provides ample space to hide the message, has become more popular.
