Introduction:

Open-Source Intelligence (OSINT) goes beyond surface-level geolocation—it reveals why a place matters by analyzing the systems that power it. Critical infrastructure mapping, which visualizes power plants, data centers, fiber routes, and telecom grids, transforms a simple coordinate into a strategic intelligence asset. This article unpacks a professional OSINT methodology that leverages public infrastructure maps to validate reports, assess disruptions, and uncover hidden relationships between physical locations and their operational backbones.

Learning Objectives:

  • Apply infrastructure mapping techniques to geolocate and contextualize any point of interest.
  • Use command-line tools (Linux/Windows) to extract network and geospatial data related to critical infrastructure.
  • Correlate infrastructure findings with real-world events such as internet outages or conflict zones.

You Should Know:

1. Understanding Critical Infrastructure Maps for OSINT

Most investigators stop at identifying a location. This technique adds layers: electricity, communications, and data transmission. The primary tool mentioned is OpenGridWorks (https://opengridworks.com), which provides open access to global power plant, substation, and transmission line data.

Step‑by‑step guide:

  • Step 1: Go to https://opengridworks.com and navigate to the map interface.
  • Step 2: Enter coordinates or a city name (e.g., “Kyiv, Ukraine”).
  • Step 3: Toggle layers: Power Plants, Substations, Transmission Lines, and Telecommunications (where available).
  • Step 4: Zoom in to identify specific infrastructure within a 5‑10 km radius of your target location.
  • Step 5: Screenshot or export the KML overlay for further analysis in Google Earth.
    Why this works: A reported drone strike near a substation explains power outages better than a generic “location X.”
  1. Geolocating Infrastructure with Linux & Windows CLI Tools
    To complement visual maps, use network intelligence commands. These help map internet exchange points, data center IP ranges, and fiber routes.

Linux commands:

 Get ASN and geolocation of an IP (e.g., a data center)
whois 8.8.8.8 | grep -i "country|netname"

Trace route to identify backbone providers
traceroute -A 1.1.1.1

Use mtr for real‑time path analysis
sudo mtr --report 8.8.8.8

Query public PeeringDB info (install via apt)
peeringdb -q "Equinix"

Windows commands (PowerShell):

 Basic whois (install sysinternals whois first)
whois 8.8.8.8 | Select-String "Country","NetName"

Traceroute equivalent
tracert 8.8.8.8

Resolve DNS and get IP
nslookup google.com

Download and query a known data center IP list
Invoke-WebRequest -Uri "https://raw.githubusercontent.com/ipverse/asn-info/main/data/AS15169.json" -OutFile "asn.json"

Step‑by‑step guide:

  • Step 1: Identify a suspected data center from OpenGridWorks (e.g., a large icon near a city).
  • Step 2: Use `whois` on the data center’s known IP range (found via public lists).
  • Step 3: Run `traceroute` to see if traffic passes through that infrastructure.
  • Step 4: Correlate results with the map to confirm physical location.

3. Cross‑referencing with Satellite Imagery & Public Datasets

Maps show where infrastructure should be; satellites show its current state. Use free imagery to verify damage or construction.

Tools:

  • Sentinel Hub (https://sentinel-hub.com) – Recent optical and radar imagery.
  • Google Earth historical view – Compare pre‑ and post‑event.

Step‑by‑step guide:

  • Step 1: Export a KML from OpenGridWorks (right‑click area → Save KML).
  • Step 2: Import KML into Google Earth Pro (File → Open).
  • Step 3: Enable “Historical Imagery” (clock icon) and scroll to the date of a reported incident.
  • Step 4: Look for burn marks, smoke, or construction near the power plant.
  • Step 5: Use Sentinel Hub’s “Custom Script” to apply false‑color (e.g., SWIR for heat detection).
    Pro tip: Power substations have distinct transformer arrays; learn their shape in satellite view to avoid misidentification.

4. Validating Fiber Routes and Undersea Cables

Internet connectivity relies on fiber corridors often hidden from plain view. Public resources like Telegeography’s Submarine Cable Map and FiberLocator (free tier) fill this gap.

Commands to discover fiber‑connected infrastructure:

 Use curl to fetch cable landing points
curl -s "https://raw.githubusercontent.com/telegeography/www.submarinecablemap.com/master/data/cable-data.json" | jq '.[] | {name, landing_points}'

Ping multiple backbone IPs to infer fiber path
for ip in $(cat backbone_ips.txt); do ping -c 3 $ip | grep "time="; done

Windows: Use pathping for combined traceroute + latency
pathping 8.8.8.8

Step‑by‑step guide:

  • Step 1: On OpenGridWorks, note the nearest transmission line.
  • Step 2: Open Submarine Cable Map and check if a cable lands within 100 km.
  • Step 3: Use `traceroute` from your location to a server in that region; look for consistent hops through the same city.
  • Step 4: Overlay fiber maps (e.g., from https://www.fiberlocator.com) to see if the route follows roads or railways.
  • Step 5: Document any correlation between fiber cuts (reported by ISPs) and physical infrastructure clusters.

5. Automating OSINT Collection with Python

To scale your investigations, automate fetching infrastructure markers and network data.

Sample Python script (requires `requests`, `geopy`):

import requests
import json

OpenGridWorks API endpoint (example – check their docs for actual)
url = "https://opengridworks.com/api/v1/power_plants"
params = {"bbox": "30.0,50.0,31.0,51.0"}  min_lon,min_lat,max_lon,max_lat
headers = {"User-Agent": "OSINT-Investigator"}

response = requests.get(url, params=params, headers=headers)
if response.status_code == 200:
plants = response.json()
for plant in plants[:10]:
print(f"{plant['name']}: {plant['capacity_mw']} MW at {plant['coordinates']}")
else:
print(f"API error: {response.status_code}")

Additional: reverse geocode infrastructure to country/city
from geopy.geocoders import Nominatim
geolocator = Nominatim(user_agent="osint_map")
location = geolocator.reverse("50.4501, 30.5234")
print(location.address)

Step‑by‑step guide:

  • Step 1: Install Python and required libraries (pip install requests geopy).
  • Step 2: Run the script to extract all power plants in a bounding box.
  • Step 3: Modify the script to query substations or fiber nodes (check OpenGridWorks API documentation).
  • Step 4: Save outputs as CSV for timeline analysis or mapping in QGIS.
    Security note: Respect rate limits; add delays (time.sleep(1)) to avoid being blocked.

6. Operational Security (OpSec) While Mapping Infrastructure

Law enforcement, hostile actors, or even corporate security teams may monitor OSINT probes. Always protect your identity.

Best practices:

  • Use a VPN or Tor when querying public maps (OpenGridWorks works over Tor).
  • Never run `nmap` or aggressive scans against IPs belonging to critical infrastructure (illegal in many jurisdictions).
  • Anonymize your `User-Agent` in scripts: 
    headers = {"User-Agent": "Mozilla/5.0 (Windows NT 10.0; Win64; x64)"}
  • For Windows, clear DNS cache after investigations: 
    ipconfig /flushdns
  • On Linux, use `macchanger` to rotate MAC addresses if scanning from a local network (not recommended over public Wi‑Fi).

Step‑by‑step guide:

  • Step 1: Launch Tor Browser and navigate to OpenGridWorks.
  • Step 2: Perform all manual mapping without logging into any accounts.
  • Step 3: Use `curl –socks5-hostname 127.0.0.1:9050` to route API calls through Tor.
  • Step 4: After investigation, clear browser caches and restart Tor circuit (New Identity).

7. Real‑World Scenario: Conflict‑Induced Internet Outage

Situation: News reports claim a city lost internet access after an airstrike. Open sources show no direct hit on telecom buildings.

Investigation using this technique:

  • Step 1: Locate the city coordinates (e.g., 31.2001° N, 29.9187° E for Alexandria, Egypt).
  • Step 2: Open OpenGridWorks and map power substations within 20 km.
  • Step 3: Identify a high‑voltage substation feeding the city’s main data center.
  • Step 4: Use Satellite Historical Imagery to see if that substation shows damage.
  • Step 5: Run `traceroute` from a known working probe to the city’s last responding IP; note where packets die.
  • Step 6: If the packet loss starts just after that substation, conclude that power loss to the data center caused the outage—not a direct cyberattack.
    Outcome: Your report validates that critical infrastructure (power) indirectly disrupted connectivity, providing actionable intelligence for humanitarian or cyber defense teams.

What Undercode Say:

  • Key Takeaway 1: Critical infrastructure maps transform raw location data into operational intelligence by revealing why a place is important—not just where it is.
  • Key Takeaway 2: Combining visual mapping (OpenGridWorks), CLI network tools (traceroute/whois), and satellite validation creates a layered OSINT methodology that can debunk false claims and identify real attack surfaces.
  • Analysis: This approach elevates OSINT from passive observation to active hypothesis testing. By focusing on dependencies (power → data center → internet), investigators can predict cascading failures. The inclusion of free APIs and automation scripts makes the technique scalable. However, practitioners must balance thoroughness with legal boundaries—scanning infrastructure IPs without authorization violates laws in many countries. The real value lies in open data correlation, not active probing. This methodology directly supports threat intelligence, journalism, and humanitarian assessments, especially in regions with information blackouts. As more critical infrastructure becomes digitized, mapping it becomes both a defense and a potential attack surface—hence the need for ethical OSINT training.
