# RISC-V: #AlphanumericShellcoding

## TL;DR

This paper demonstrates how to create RISC-V shellcodes that are ASCII-readable using only alphanumeric characters and a few special symbols, facilitating stealthy code injection.

## Contribution

It introduces a method for designing RISC-V shellcodes with restricted ASCII characters, enhancing evasion techniques in security contexts.

## Key findings

- Shellcodes can be constructed using only specific ASCII characters.
- The method enables stealthy code execution in RISC-V architectures.
- Potential applications in security and malware development.

## Abstract

We explain how to design RISC-V shellcodes capable of running arbitrary code, whose ASCII binary representation use only letters a-zA-Z, digits 0-9, and either of the three characters: #, /, '.
