EDRs facilitates red teaming by compiling a comprehensive list of hooked APIs implemented by various Endpoint Detection and Response (EDR) solutions on Windows. The project aims to provide security professionals with data on how these tools monitor and control system behavior. It achieves this by collecting and organizing lists of APIs hooked by EDRs, offering insights into their detection mechanisms and potential bypass techniques. The primary approach involves gathering information from various sources and presenting it in an easily accessible format.
The project's strength lies in its curated and constantly updated lists of hooked APIs, which are sourced from a variety of EDR solutions. It provides direct links to lists for specific vendors. The inclusion of both Excel and Markdown formats for the hook lists enhances accessibility. The repository is community-driven, allowing for contributions and updates from security researchers.
- API Hook Lists: Provides categorized lists of hooked APIs for major EDR vendors like CrowdStrike, SentinelOne, Cylance, and more. Each list is specifically for ntdll.dll APIs.
- Hook Finder Tool: Offers a command-line utility to identify hooked APIs within a target DLL, simplifying the process of data collection.
- Kernel Mode Hooks: Identifies and flags hooks operating in kernel mode, highlighting potential challenges in unhooking these mechanisms.
- Data Formats: Offers data in both Excel and Markdown formats for easy import into various analysis tools and platforms.
- Community Contributions: Relies on community contributions and shared data, fostering collaborative security research.
The project appears to be actively maintained, with recent commits indicating ongoing updates to the hook lists. The inclusion of contributions from multiple individuals suggests a healthy community. The presence of comprehensive listings for numerous EDR products suggests a mature and well-established effort. The project's reliance on external sources means the data's completeness and accuracy depend on these sources.
Security researchers, penetration testers, and security analysts benefit from EDRs by gaining valuable insights into how EDRs operate and detect malicious activities. It assists in developing evasion techniques, understanding EDR capabilities, and improving security defenses. By providing detailed API hook lists, EDRs offers a more granular understanding compared to general EDR documentation, facilitating targeted analysis and research.
