Writing an OTA loader for ATmega128RFA1 (part of the Smart Response XE device)

Posted on

It all started with the author purchasing an interesting device on the secondary market - Smart Response XE (brief description). It is intended for schools: each student in the class receives a device similar to an electronic notepad or a translator from the nineties, the teacher asks a question, and the students type their answers on the devices' keyboards, which are transmitted via radio channel (802.15.4) to a receiver connected to the teacher's PC.

LSB Steganography

Posted on

A long time ago, I wrote my first post on Habr. This post was dedicated to a quite interesting problem, namely steganography. Of course, the solution proposed in that old topic cannot truly be called steganography in the strict sense of the word. It's just a game with file formats, but nonetheless, quite an interesting game. Today, we will try to delve a little deeper […]

Steganography beyond files: hiding data directly in sectors

Posted on

A Brief Introduction Steganography, if anyone remembers, is the hiding of information within some containers. For example, in images (discussed here and here). You can also hide data in the metadata tables of the file system (this was written about here), and even in the service packets of the TCP protocol. Unfortunately, all these methods have one drawback: to discreetly 'inject' information into […]

In this article, I will describe some theoretical aspects, as well as how this small program was created. Theoretical Part GIF Format GIF (Graphics Interchange […]

TCP steganography or how to hide data transmission on the Internet

Posted on

Polish researchers have proposed a new method of network steganography based on the peculiarities of the widely used TCP transport layer protocol. The authors believe that their scheme could be used, for instance, to send hidden messages in totalitarian countries that impose strict internet censorship. Let’s try to understand what the innovation consists of and how useful it really is. First, we need to define […]

Steganography in file systems

Posted on

Hello, Habr. I would like to introduce you to a small project on steganography that I created in my free time from studying. I made a project on the covert storage of information in the file system (hereafter FS). This can be applied for stealing confidential information for educational purposes. The experimental sample chosen was the rather old Linux file system ext2. Implementation Considerations for Implementation If one can 'really dig deep' […]
