Abstract

Steg Online is an open-source Cybersecurity & Ethical Hacking project. A web-based, accessible and open-source port of StegSolve. A web-based, enhanced and open-source port of StegSolve. Upload any image file, and the relevant options will be displayed. It is built using TypeScript. Key capabilities include: Browse through the 32 bit planes of the image; Extract and Embed data using LSB steganography techniques; Hide images within other image bit planes. The complete source code is publicly available on GitHub under the Do What The F*ck You Want To Public License, making it a useful reference for students building a Cybersecurity & Ethical Hacking mini project or final-year project.

1. Introduction

A web-based, enhanced and open-source port of StegSolve. Upload any image file, and the relevant options will be displayed. View a live demo at http://stegonline.georgeom.net/.

2. Objective
