# CrystalC2 ## CrystalC2 A command and control framework, mostly to keep myself occupied and out of trouble... ### Highlights CrystalC2's post-exploitation agent is built from modular position-independent code (PIC) parts, weaved together using [Crystal Palace](https://tradecraftgarden.org/). The purpose of the project is to explore the left and right bounds of CPL's [Aspect-Oriented Programming](https://aff-wg.org/2025/11/10/tradecraft-engineering-with-aspect-oriented-programming/) (AOP) and [bin2bin](https://aff-wg.org/2026/01/13/keeping-bin2bin-out-of-the-bin/) paradigms when applied to various aspects of a C2 agent. Challenge areas that come to mind include: * load-time evasion: loading PIC into a process and bootstrapping its execution. * runtime evasion: minimising the indicators of PIC running in memory. * post-exploitation evasion: running 3rd party code/tools. ### Outcomes The long-term goal is to provide users with the flexibility to apply any evasion tradecraft strategies they wish to the Beacon agent and its loader. --- # Agent Instructions: Querying This Documentation If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.
