This repository contains the code we developed, along with cover files generated by our approach. It also includes the real development files used in our experiments. Since no public implementation of the English Shellcode method is available, we tried our best to implement this method and provide it in the repository as well.
The code in this reporitory is divided into two part:
- The
prompts: The prompts used in our experiments. - The
decoder: Several decoder implementations, including those described in the paper as well as customized versions that handle padding. The decoders works with block size 2 by default.
Several decoders are provided in Shell, Python, and Perl, along with a customized decoder for padded cover files. You can run
cat poem.txt | ./decoder/decoder.sh | xxd
to verify the correctness of the payload encoded in the poem example shown in the paper in Figure 1.
More details can be found in the directory decoder.
