Empire is a post-exploitation command-and-control (C2) framework designed for red team operations. It deploys and manages agents written in PowerShell, Python, C#, Go, and C across Windows, Linux, and macOS, using encrypted communication channels over HTTP, HTTPS, and SMB. The framework executes over 400 built-in modules for reconnaissance, privilege escalation, credential theft, and lateral movement, and provides a modular engine for authoring custom attack modules. What sets Empire apart is its multi-language agent deployment system, which allows operators to choose implants that suit each

BeEF is a modular security testing environment designed for browser exploitation and web application auditing. It functions as a platform for security professionals to evaluate client-side defenses by injecting persistent scripts into web browsers, establishing a bidirectional communication channel for remote command execution and data exfiltration. The framework distinguishes itself through its ability to use compromised browser sessions as proxies to conduct internal network reconnaissance, effectively bypassing perimeter security controls. It utilizes an event-driven control interface and

A post exploitation framework designed to operate covertly on heavily monitored environments

Sliver is a command and control framework designed for adversary emulation and security assessment operations. It provides a centralized platform for managing remote systems, enabling security professionals to coordinate multi-operator sessions and maintain persistent, secure communication channels across diverse network environments. The framework distinguishes itself through its focus on stealth and infrastructure flexibility. It utilizes dynamic payload obfuscation to generate unique binaries and supports in-memory execution to minimize disk artifacts. Communication is secured through mutu

Pivot into the internal network by deploying HTTP agents. Pivotnacci allows you to create a socks server which communicates with HTTP agents. The architecture looks like the following:

Gcat A stealthy Python based backdoor that uses Gmail as a command and control server

An asynchronous, collaborative post-exploitation agent powered by Python and .NET's DLR

Proof of concept MacOS post exploitation tool written in Swift. Designed as a POC for blue teams to build macOS detections. Author: Cedric Owens

NimPlant - A light first-stage C2 implant written in Nim|Rust and Python

Covenant is a .NET-based command and control framework designed for red team operations and adversary simulation. It serves as a collaborative platform for coordinating security assessments, managing remote implants, and executing tasks on compromised systems through a centralized server. The project is distinguished by its dynamic payload generator, which compiles and obfuscates executable binaries and scripts on the fly to bypass detection. It further separates itself through a collaborative environment that allows multiple authenticated operators to share a synchronized state, track operat

WEASEL is a small in-memory implant using Python 3 with no dependencies. The beacon client sends a small amount of identifying information about its host to a DNS zone you control. WEASEL server can task clients to execute pre-baked or arbitrary commands.

Windows persistence toolkit written in C#. For detailed usage information on each technique, see the Wiki.

p0wny@shell:~# is a very basic, single-file, PHP shell. It can be used to quickly execute commands on a server when pentesting a PHP application. Use it with caution: this script represents a security risk for the server.

PetaQ is a malware which is being developed in .NET Core/Framework to use websockets as Command & Control (C2) channels. It's designed to provide a Proof of Concept (PoC) websocket malware to the adversary simulation exercises (Red & Purple Team exercises).

C3 (Custom Command and Control) is a tool that allows Red Teams to rapidly develop and utilise esoteric command and control channels (C2). It's a framework that extends other red team tooling, such as the commercial Cobalt Strike (CS) product via ExternalC2, which is supported at release. It…

The Discretionary ACL Modification Project: Persistence Through Host-based Security Descriptor Modification.

Havoc is a post-exploitation framework used for red team operations. It provides a centralized command and control system for managing remote agents through persistent network connections and customizable communication profiles. The framework focuses on security evasion and stealth, utilizing indirect syscall execution, return address spoofing, and hardware-breakpoint patching to bypass endpoint detection and response tools. It includes a payload generation workflow to create executable shellcode or DLLs for initial remote access. The system covers a broad range of operational capabilities,

dnscat2 is a DNS tunneling tool and covert command and control server that encapsulates encrypted traffic within DNS queries and responses. It functions as an encrypted DNS proxy designed to bypass network firewalls and establish communication paths when standard outbound ports are blocked. The project enables the creation of covert network channels by acting as an authoritative nameserver. It supports remote command execution through interactive shells and provides a mechanism for tunneling TCP network traffic to reach restricted remote hosts. The system includes capabilities for multiplexe
