Security-Robustness Trade-Offs in Diffusion Steganography: A Comparative Analysis of Pixel-Space and VAE-Based Architectures

Current generative steganography research mainly pursues computationally expensive mappings to perfect Gaussian priors within single diffusion model architectures. This work introduces an efficient framework based on approximate Gaussian mapping governed by a scale factor calibrated through...

Stegify - Go Tool For LSB Steganography, Capable Of Hiding Any File Within An Image

stegify is a simple command line tool capable of fully transparent hiding any file within an image. This technique is known as LSB Least Significant Bit steganography. Demonstration Carrier Data Results The Result file contains the Data file hidden in it. And as you can see it is fully transparen...

50m-ctf: CTF write-up: c8889970d9fb722066f31e804e351993

So the CTF starts with this tweet. F434370 The first image is about the 50 million in bounties but the second one looks related to the CTF. The first thing that comes to mind when relating CTFs and images is "steganography". Using the all purpose steg tool zsteg as our first resort, we discover...
