Huginn Net is a multi-protocol passive fingerprinting library that allows for the identification of operating systems and services through TCP, HTTP, and TLS traffic analysis without active probes. Built in Rust and compliant with open-source specifications, it's designed for high efficiency with minimal latency, providing reliable insights from network traffic.
Huginn Net is a robust multi-protocol passive fingerprinting library designed for the analysis of TCP, HTTP, and TLS traffic, leveraging open-source methodologies. Built entirely in Rust, Huginn Net delivers fast and reliable data extraction from network packets without actively probing the environment. By employing p0f for TCP and JA4 for TLS protocols, it provides unparalleled accuracy and efficiency, with an impressive average processing time of approximately 3.1ms per packet.
Key Features
Huginn Net excels in the following areas:
- Operating System Identification: Utilizing TCP fingerprinting inspired by p0f, Huginn Net can discern the OS type, version, and network stack of remote hosts.
- Application and Browser Detection: By examining HTTP headers and implementing JA4 TLS client fingerprinting, it accurately identifies applications and web browsers.
- Network Infrastructure Insights: The library is capable of detecting intermediary devices such as proxies and load balancers.
- Client Capabilities Profiling: Insights into supported TLS versions, cipher suites, and extensions are provided, enhancing understanding of client capabilities.
