Nimhawk: Advanced Nim-Based C2 Framework Revolutionizes Red Team Operations

by · Published · Updated

Nimhawk is an advanced command and control (C2) framework that builds upon the exceptional foundation laid by Cas van Cooten (@chvancooten) with his NimPlant project. Cas’s innovative work in developing a lightweight implant written in Nim has been groundbreaking for this project.

This project would not exist without Cas’s technical expertise, dedication to open source, and commitment to knowledge sharing. Nimhawk expands on NimPlant’s original functionality with:
