Heroinn: Open-Source Cross-Platform C2 and Post-Exploitation Framework Built with Rust

Heroinn, an open-source Command and Control (C2) and post-exploitation framework implemented in Rust, has been released for security researchers and red team practitioners. Designed with memory safety and a lightweight runtime footprint in mind, Heroinn delivers a versatile cross-platform architecture that spans Windows, Linux, macOS, and BSD systems.

In contemporary adversary emulation and penetration testing engagements, security teams increasingly require cross-platform C2 toolsets capable of operating seamlessly across diverse enterprise operating systems and infrastructure topologies. Heroinn leverages the core advantages of Rust to provide stable session control, comprehensive telemetry gathering, and post-exploitation primitives within a unified operator workflow.

Cross-Platform Architecture and Multi-OS Compatibility

A central design pillar of Heroinn is its broad operating system support across enterprise endpoints and servers:

  • Supported Platforms: Compatible with Windows 10+ (including Windows Server 2019+), Linux distributions, BSD variants, and macOS (OSX).
  • Rust-Based Foundation: Offers enhanced memory safety over traditional C/C++ implementations while compiling into compact, standalone binaries with minimal runtime dependencies.

This cross-platform foundation allows security operators to maintain a consistent engagement posture across heterogeneous target environments.

GUI Dashboard, Interactive PTY Shell, and Resumable File Management

Heroinn integrates several essential operational tools designed to streamline testing workflows and improve operator efficiency:

  • Graphical User Interface (GUI): Provides an intuitive graphical control interface to monitor connected agent sessions, inspect endpoints, and orchestrate tasks from a single dashboard.
  • Interactive PTY Shell: Delivers full interactive pseudo-terminal (PTY) capabilities beyond basic command execution, enabling rich terminal interactions.
  • System Information Collection: Built-in modules gather essential system metadata, including hardware configuration, OS details, networking state, and active processes.
  • Large-File and Resumable File Transfer: Includes an integrated file manager capable of handling large-scale file transfers with built-in support for resuming interrupted connections.

Multi-Protocol Networking and Research Scope

To adapt to varying network egress restrictions and segmentation policies, Heroinn provides flexible transport layer options:

  • Supported Protocols: Supports communication over standard TCP, web-friendly HTTP, and reliable UDP for resilient packet delivery under varying network conditions.
  • Intended Use and Research Guidelines: Heroinn is developed strictly for educational purposes, defensive validation, authorized penetration testing, and red team simulation. Unauthorized deployment or malicious use against systems without explicit prior consent is strictly prohibited.
