项目说明

![Made-with-Rust]()
![License: MIT]()

A minimal, cross‑platform ransomware implementation in Rust - designed for defenders, security researchers, and educators who want to see exactly how modern ransomware works under the hood, so they can build better detection and mitigation strategies.

🔍 Why Nakitai?

Ransomware remains one of the most sophisticated and damaging threats in cybersecurity today. Nakitai is not intended for malicious use - instead, it serves as:

By stepping through the same cryptographic primitives, file tra techniques, and error handling that real ransomware families use, defenders gain critical insights into:

1. Key management & exchange (x25519 keypairs).
2. File enumeration & selecti.
3. Error‑resilient design for partial data recovery.
4. Integration points for hooking/detecting anomalous behavior.

🚀 Getting Started

Prerequisites

Build & Generate Keys

1. Build the keypair tool & generate:

2. Ensure the public key is tracked so that Nix can access it (it's git‑ignored by default):

Build Binaries

All executables end up in result/bin/:

🛡️ How to Use (Defensi)

1. Run in a sandbox with sample files to observe:

2. Monitor system calls (e.g., via strace, Windows ETW) to capture file‑access patterns.
3. Inspect logs: hook your EDR or filesystem filter driver to see exactly which APIs get invoked.
4. Feed generated traffic into your SIEM or threat‑hunting tools; develop detection rules around:
- Unusual large‑scale file writes
- Consistent use of high‑entropy data blocks
- In-memory key exchange anomalies
