GhostSys is an academic research project that presents a proof-of-concept toolkit showcasing five syscall evasion techniques compliant with CET (Control-Flow Enforcement Technology). This toolkit is designed to effectively bypass advanced endpoint detection and response systems (EDRs) on Windows 11, including leading solutions like SentinelOne Singularity XDR, CrowdStrike Falcon, and Microsoft Defender for Endpoint.

Features

• Demonstrates techniques such as gadget discovery and Spectre-style hook probes.
• Introduces a first-ever in-kernel eBPF JIT abuse method, open-source and reproducible.
• Accompanies a comprehensive academic research paper provided in PDF format, along with the LaTeX source code.

Important Note

The research paper is currently in the publication process and will remain accessible within this repository until published.

This project is intended strictly for educational, academic, and red team research use. The techniques may help enhance system defenses rather than facilitate unauthorized access or exploit vulnerabilities. Users must employ these methods responsibly, ethically, and only in controlled environments or with explicit consent. Users are fully responsible for any implementation of the provided code.

Example Usage
