Open-source alternatives to StegaToolkit

Aletheia is an open source image steganalysis tool for the detection of hidden messages in images. To achieve its objectives, Aletheia uses state-of-the-art machine learning techniques. It is capable of detecting several different steganographic methods as for example F5, Steghide, LSB…

Aletheia is an open source image steganalysis tool for the detection of hidden messages in images. To achieve its objectives, Aletheia uses state-of-the-art machine learning techniques. It is capable of detecting several different steganographic methods as for example LSB replacement, LSB…

Stegasaurus 2 is a steganography library. Maybe someday it will also be an application which allows non programmers to do steganography. For now though my focus is on making more steganographic methods available so no GUI or web stuff just yet.

cookie-stego: stegnalysis tools

Steganalyse.py is a Python tool that uses SVMs and Logistic Regression to classify image and video files as being either clean or steganographic.

空域编码是指在图像空间域进行编码，也就是直接针对图像像素进行编码 对像素进行编码，如LSB算法，主要有下面两种方式 光栅格式 调色板格式 GIF(graphics interchange format) 一个图像编码标准往往包括多类编码方法，一个图像仅仅是其一类方法的实例。例如，常见的BMP（Bitmap）、 TIFF（ Tagged Image File Format）、 PNG（Portable Network Graphics）均支持光栅格式与调色板格式编码，对这两种格式 编码分别又支持多种具体编码方法…

Detecting whether steganography is present in an image using machine learning. - Least significant bit (LSB) embedding functions using various embedding location sequences. - Generates dataset from set cover images. - Creates feature vectors from statistical moments of autocorrelation and…

CTF'lerde Steganography kategorisindeki bazı sorular steghide aracıyla çözülmektedir, flag dosyası resimden elde edilmektedir. Bazı durumlarda bu işlem belirlenmiş bir parola ile gerçekleşir.

A rich toolkit of steganography solutions to CTF challenges

IStego100K: Large-scale Image Steganalysis Dataset, mixed with various steganographic algorithms, embedding rates, and quality factors.

This repo provides state-of-the-art pre-trained models for steganalysis in the JPEG domain, trained and used to win the ALASKA 1 steganalaysis challenge. Details about the architectures can be found in our paper.
