Open-source alternatives to APTSimulator

Caldera is an adversary emulation platform and command and control framework designed to simulate cyber attack patterns. It functions as an automated red team tool and threat framework orchestrator, executing attack sequences based on standardized cybersecurity threat frameworks to validate security defenses and detection capabilities. The platform distinguishes itself through the dynamic compilation of customized executable payloads and the use of framework-mapped adversary modeling to structure attack techniques. It manages asynchronous agents on targeted endpoints via a central server acce

Atomic Red Team is an adversary simulation tool and detection validation suite designed to emulate attacker behaviors. It functions as a security control testing framework that uses a library of portable tests to verify if security monitoring and alerting systems correctly identify specific malicious techniques. The project serves as a MITRE ATT&CK emulation framework, mapping individual test executions to a standardized industry taxonomy of adversary behaviors. This mapping allows for the validation of security controls against the MITRE ATT&CK matrix to identify gaps in detection and respon

Empire is a command and control framework and post-exploitation toolkit used for network penetration testing. It serves as a centralized platform for coordinating remote agent communication and automating the delivery of security testing payloads to target systems. The project provides a suite of modules for host reconnaissance, lateral movement, and credential harvesting across corporate environments. It functions as a remote administration tool to maintain persistence and execute commands on compromised hosts. The framework incorporates capabilities for agent orchestration and the executio

PowerSploit is a collection of PowerShell modules designed for security assessment, penetration testing, and red team operations. It provides a framework for auditing Windows system configurations and evaluating the effectiveness of security defenses within an enterprise environment. The framework focuses on techniques that leverage native system administration tools and scripting environments to perform operations. It includes capabilities for executing arbitrary commands, escalating user privileges, and maintaining system persistence through event subscriptions. By utilizing in-memory execu

Monkey is an adversary emulation platform and breach and attack simulation tool designed to test network defenses through automated lateral movement and exploit delivery. It functions as a network security testing system that evaluates security posture by attempting to propagate through vulnerabilities and extract sensitive system credentials. The platform distinguishes itself by simulating specific real-world attacker behaviors, such as ransomware encryption, cryptojacking, and the theft of browser-stored credentials and secure shell keys. It utilizes binary hash randomization to evade antiv

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

Apfell is a red teaming framework and command and control server designed for collaborative adversary simulation. It provides a centralized infrastructure to manage remote agents and distribute tasking across multiple operating systems using a message broker for real-time synchronization. The system functions as a distributed agent orchestrator, allowing teams to coordinate complex attack chains and synchronize container data. It features a multi-platform payload manager that enables the downloading and integration of custom agents and command profiles from remote repositories. The platform

This project is a collection of technical resources, blueprints, and guides for building resilient and stealthy red team infrastructure. It provides a comprehensive framework for designing offensive security environments that resist detection and remain operational throughout security engagements. The repository distinguishes itself through detailed playbooks for adversary simulation and hardening manuals. It covers advanced obfuscation techniques such as domain fronting, the use of platform-as-a-service redirectors, and the leveraging of third-party content sites to inherit domain reputation

Automated Attack Simulation in the Cloud, complete with detection use cases.

TTPForge is a cyber attack simulation platform designed and built by Sam Manzer (@d3sch41n), Alek Straumann (@CrimsonK1ng), and Geoff Pamerleau (@Sy14r), and including subsequent contributions from many good folks in Meta’s Red, Blue, and Purple security teams. Jayson Grace (@l50) migrated the…

Impacket is a collection of Python classes designed for the construction, manipulation, and analysis of low-level network packets and services. It functions as a framework for building custom network tools, providing a programmatic interface to interact with communication protocols and service architectures. The library provides primitives for managing authentication, session state, and remote procedure calls within network environments. By offering a modular class hierarchy, it allows for the assembly of network packets and the implementation of specialized communication stacks. The project
