Introduction:

In the rapidly evolving landscape of cybersecurity, Open Source Intelligence (OSINT) has moved from a niche skill to a core competency for threat hunters, penetration testers, and security analysts. As we move through 2026, the fusion of traditional geospatial intelligence (GEOINT) with real-time data streams provides an unprecedented view of adversarial infrastructure and physical assets. Leveraging publicly available tools like ADS-B Exchange and Sentinel Hub allows defenders to map attack surfaces that exist in both the digital and physical realms, turning passive data collection into active defensive strategies.

Learning Objectives:

  • Understand how to integrate aviation and maritime tracking tools (ADS-B Exchange, MarineTraffic) into threat intelligence gathering.
  • Learn to utilize live mapping services (LiveUAMap, S2U Map) for geopolitical risk assessment.
  • Master the application of satellite imagery platforms (Sentinel Hub, Google Earth Pro) for infrastructure verification and footprint analysis.

You Should Know:

  1. Mastering Air and Sea: Tracking Adversarial Movement with ADS-B Exchange and MarineTraffic
    Unlike commercial flight trackers that filter data for privacy or business reasons, ADS-B Exchange (now operating as a combined entity in 2026) aggregates unfiltered Automatic Dependent Surveillance–Broadcast data. For a security analyst, this is invaluable for tracking private military aircraft, government transports, or surveillance planes that are often hidden on other platforms.

Step‑by‑step guide:

  • Navigate to the aggregated platform (likely a merger of the original ADS-B Exchange and other aggregators). Use the “History” or “Playback” feature to rewind time and analyze aircraft that were loitering near sensitive infrastructure during a specific incident.
  • Cross-reference the hex code (ICAO 24-bit address) with public registries to identify the registered owner. Often, shell companies are used; utilize the aircraft’s previous flight paths to guess its base of operations.
  • On MarineTraffic, apply the same logic. Use the “Ports” filter to monitor vessels loitering outside major data cable landing points. You can set up alerts for when specific types of vessels (e.g., cable-laying ships) enter a restricted economic zone.
  1. Geopolitical Threat Mapping: Leveraging LiveUAMap and S2U Map
    Understanding the physical security landscape is crucial for cloud and data center security posture. LiveUAMap and S2U Map provide crowdsourced and official data on conflict zones, which is critical for risk assessments.

Step‑by‑step guide:

  • During a red team exercise, use LiveUAMap to assess if a target organization’s remote office or data center is located within a zone of active conflict or protest. This informs the physical security portion of the penetration test.
  • Use S2U Map (a specialized map for tracking Russian and Ukrainian military activity) to verify if specific electronic warfare systems are reported in a region that could disrupt satellite communications for a client.
  • Linux Command Integration: Automate the collection of this data using `curl` to hit any available public APIs (if the map services provide them) and `jq` to parse the JSON output for keywords related to the target’s location.
    curl -s "https://api.liveuamap.com/events?bbox=target_longitude,target_latitude" | jq '.[] | select(.title | contains("drone"))'
    
  1. Satellite Reconnaissance: Sentinel Imagery and Google Earth Pro for Infrastructure Hardening
    Satellite imagery is no longer just for nation-states. With Sentinel Hub (ESA’s Copernicus program) and Google Earth Pro, security professionals can conduct non-intrusive physical penetration testing preparation.

Step‑by‑step guide:

  • In Google Earth Pro, use the “Historical Imagery” slider. Look for changes in a building’s roofline (new satellite dishes), construction of new fencing, or the presence of temporary structures that might indicate a new datacenter expansion.
  • For Sentinel Hub (or the EO Browser), use the “NDVI” (Normalized Difference Vegetation Index) filters. While typically used for agriculture, this can highlight heat signatures or vegetation stress near underground fiber optic lines, potentially revealing their path if the ground has been recently disturbed.
  • Windows Command Integration: Use the Windows Task Scheduler to trigger a Python script (using the `sentinelhub` PyPI package) that downloads fresh imagery of a client’s perimeter daily. Compare the images using OpenCV to detect physical changes (new construction, vehicles) automatically.

4. Cross-Platform Correlation: Building a Unified OSINT Dashboard

The real power in 2026 is correlating the data. A suspicious vessel near a cable landing zone (MarineTraffic) during a time when a loitering aircraft (ADS-B Exchange) is overhead, while a conflict map shows instability in that region, paints a complete threat picture.

Step‑by‑step guide:

  • Set up a Maltego transform. While Maltego traditionally handles domain and network data, you can create custom transforms that pull latitude/longitude data from these mapping tools and plot them as entities on a graph.
  • Use Python to script the correlation. Extract coordinates from MarineTraffic scrapes, feed them into a geofencing algorithm, and if an aircraft is within a 10-mile radius simultaneously, log the event as a “High Priority Anomaly.”
    Pseudocode for correlation
    ship_data = get_marine_data(zone)
    flight_data = get_adsb_data(zone)
    for ship in ship_data:
    for flight in flight_data:
    if haversine(ship['lat'], ship['lon'], flight['lat'], flight['lon']) < 10:
    log_anomaly(ship, flight)
    

5. Tool Configuration: Automating Sentinel Hub API Access

To make satellite data a regular part of your threat feed, you must automate it.

Step‑by‑step guide:

  1. Register for a free Sentinel Hub account (or the Copernick Data Space Ecosystem as of 2026).
  2. Create an OAuth client to get a access token.
  3. Use `curl` to request imagery for a specific bounding box (your target’s coordinates).
    curl -X POST https://identity.dataspace.copernicus.eu/auth/realms/tdre/protocol/openid-connect/token \
    -d "client_id=your-client-id" \
    -d "username=your-username" \
    -d "password=your-password" \
    -d "grant_type=password" > token.json
    ACCESS_TOKEN=$(jq -r '.access_token' token.json)
    
  4. Use the token to request a true-color image of the target facility and store it for the “Physical Change Detection” log.

What Undecode Say:

  • The Convergence of Physical and Digital: The line between GEOINT and OSINT is officially gone. In 2026, a robust security assessment must include physical layer reconnaissance, as digital attacks often have physical precursors (e.g., surveying a building before a breach).
  • Automation is Non-Negotiable: Manually checking these maps is insufficient. Security teams must script and automate the ingestion of this data into their SIEMs or threat intelligence platforms to catch the “needle in the haystack” correlations that indicate a sophisticated, multi-domain adversary.

Prediction:

Within the next 12 months, we will see the rise of “OSINT-based Adversary Emulation,” where red teams use live satellite and tracking data to time their physical and digital attacks. Defenders will respond by adopting “digital twin” defenses that use the same OSINT data to predict attack paths, effectively turning the recon tools of the adversary into the early warning systems of the defender.
