Shadow Hunter
Shadow Hunter is a lightweight network intelligence and OSINT reconnaissance tool designed for investigating internet infrastructure, autonomous systems (ASN), routing activity, and network ownership. The application provides investigators, cybersecurity researchers, and network engineers with rapid visibility into the operational structure of the internet by correlating registry data, routing intelligence, and infrastructure discovery tools.
Modern internet infrastructure is composed of thousands of autonomous systems exchanging routing information through the Border Gateway Protocol (BGP). Investigating these relationships typically requires multiple tools and registry queries across several platforms. Shadow Hunter consolidates these capabilities into a single interface that allows analysts to pivot quickly between IP addresses, ASN ownership records, routing policies, and live network path data.
Network Intelligence & OSINT Reconnaissance
Shadow Hunter is designed specifically for analysts performing infrastructure investigation and internet intelligence research. The tool provides direct access to several critical data sources used in network investigation workflows including IRR route objects, RPKI route authorization records, and active BGP prefix announcements.
These data sources make it possible to determine whether an autonomous system is actively routing traffic, inactive, or operating in a partially hidden state where routing policy exists but no active BGP announcements are visible. This capability is particularly useful when investigating suspicious hosting infrastructure, analyzing threat actor network resources, or identifying unusual routing behavior across the global internet.
By combining IP to ASN resolution, WHOIS registry records, reverse DNS discovery, and traceroute path analysis, Shadow Hunter allows analysts to pivot from a single IP address to the infrastructure responsible for routing that traffic. This approach dramatically speeds up reconnaissance during network investigations and infrastructure analysis.
Core Investigation Capabilities
- Autonomous System (ASN) reconnaissance and routing status classification
- IRR routing policy discovery and route object inspection
- RPKI route authorization analysis
- BGP prefix activity detection
- IP address to ASN ownership mapping
- WHOIS registry intelligence
- Reverse DNS host discovery
- Traceroute network path analysis
Together these capabilities provide a rapid method for investigating network ownership, understanding routing relationships, and identifying anomalies within the global routing ecosystem.
Linux Binary Release
The Linux binary version of Shadow Hunter is compiled as a standalone executable for Linux systems. This version requires no Python installation and can be launched immediately after download.

Because Shadow Hunter is built entirely in Python using Tkinter, it can be easily extended with additional intelligence capabilities such as BGP route history analysis, ASN relationship mapping, certificate transparency pivots, or automated detection of routing anomalies across large ASN datasets.
Use Cases
Shadow Hunter can be used in a wide variety of investigative scenarios including cybersecurity research, threat intelligence analysis, infrastructure reconnaissance, and academic research into the structure of the internet. Security analysts can quickly identify the autonomous system responsible for hosting suspicious infrastructure, examine routing policies associated with that network, and trace the network path through upstream providers and internet exchange points.
Researchers studying routing anomalies such as BGP hijacks, route leaks, or infrastructure migrations can also use the tool to correlate registry data with observed routing behavior. Because the platform combines multiple intelligence sources in one interface, it significantly reduces the time required to investigate complex network ownership relationships.
Whether you are performing OSINT investigations, analyzing suspicious network infrastructure, or studying the architecture of the internet backbone, Shadow Hunter provides a focused and efficient reconnaissance platform for modern network intelligence workflows.
