Undersea Cable Outages Expose Pacific Defense Data Routes

[FEATURED_IMAGE]

Why a Bent Pipe in the Pacific Matters to You

There are 464 active submarine cables worldwide; 53 touch the Pacific islands. Ten of those carry SIPRNet, JWICS, and contractor telemetry for missile defense. When a typhoon or a trawler drags an anchor across one, traffic fails over to paths that were never designed for classified data. BGP optimists call it “resilience.” Hackers call it “a wider surface.” OSINT analysts call it “Tuesday.”

With military teams already using OSINT to boost threat intelligence and battlefield awareness, the next logical step is mapping physical layer chokepoints the same way we map IP space. Spoiler: it is cheaper than a carrier group and you can do it from a WeWork.

How OSINT Sees a Cable Before Navies Do

OSINT is not magic; it is just noisy data you learn to filter. Here is the playbook my red-team interns run every quarter:

• Fishing notices: Taiwanese and Japanese authorities publish NOTMAR (Notice to Mariners) 48 h before any survey ship leaves port. Cross-reference hull names with cable-layer databases and you get a maintenance window.
• Port webcam scraping: Tumon Bay and Pohnpei webcams occasionally show cable drums on the pier. Screenshot, EXIF for time stamp, geolocate with skyline. Bingo—projected landing points.
• LinkedIn desperation: Contractors brag. Search “project manager + GUAM HONOTUA + fiber.” They post team photos with cable ships in the background. Run a reverse-image search to get IMO numbers.
• Automatic Identification System (AIS) gaps: Ships disappear when transponders go dark. Draw a 30 nmi radius around each cable waypoint; if a vessel vanishes inside that circle, you have a probable fault.

Kindi, our in-house AI graph platform, automates the above. You dump AIS feeds, NOTMAR PDFs, and LinkedIn posts into Kindi, it spits out a heat map of likely break points. Analysts drink less coffee, admirals get prettier slides.

Mapping the Pacific Backbone with Free Tools

You do not need TS/SCI to see the wires. Here is a starter kit that keeps you legal:

Export everything to a single KMZ, drop it into Kindi, and you have a living document that updates itself when a typhoon swerves or a fisherman gets clumsy.

Real-World Case: 2025 Palau-to-Yap Fault

On 14 Aug 2025 the Palau Coral cable went dark at 0347 UTC. Within 12 min:

• BGPmon showed AS9246 (Palau Telecom) withdrawing 103.15.248.0/22.
• AIS showed cable ship Kokoro steaming from Leyte toward the fault at 14 kt.
• LinkedIn contractor “excited for emergency splice op” posted selfie with GPS tag 7.342, 134.523—smack on the cable.
• JWICS latency to Camp Navasei spiked from 42 ms to 312 ms, routing via Hawaii.

All of that was public. None of it hit classified briefings until 36 h later. An OSINT team could have predicted the reroute and pre-hardened the alternate path.

Weaponizing Cable Intelligence for Red Teams

Red teams love single points of failure. If you know DoD flips to a commercial carrier, you target that carrier’s NOC engineers. A few phishing themes that work:

• “Urgent BGP community change required due to cable fault, please validate.”
• “New submarine cable maintenance window—click to reschedule your circuit.”
• “Microwave backup survey; download form to keep your SLA credits.”

Pair the phish with a fake landing page cloned from the carrier’s real portal. Because the outage is live, the urgency feels real. Payloads get executed, VPN creds harvested, and you pivot into the military network riding the same detour path the traffic is using.

If you need help automating the recon stage, red-team OSINT reconnaissance guides walk through harvesting engineers’ social graphs and building believable pretexts.

Blue-Team Defense: Building a Cable Situational Report

Defense is just attack with a budget. SOC analysts should treat every cable fault like a cyber event. Workflow:

1. Pull NOTMAR RSS into your SOAR.
2. Correlate with AIS disappearances inside cable polygons.
3. Auto-create a Jira ticket and tag all AS numbers that traverse the affected segment.
4. Check RPKI validity for those AS paths; if you see ROA anomalies, escalate.
5. Push a STIX object to your threat feed so the intel shop sees it in real time.

That single playbook dropped our median detection time from 18 h to 47 min across three Pacific exercises. For more enrichment tricks, see OSINT for SOC enrichment.

Commercial Contractors: What You Must Disclose

DFARS 252.204-7012 and the new CMMC Level 3 scoping guide both require “geographic diversity” for controlled unclassified information. Translation: if your only path to a CONUS data center is a single submarine cable, you fail. OSINT lets you prove diversity without paying for a penetration test:

• Screen-capture the TeleGeography map showing two separate cables.
• Run traceroute from your Guam node; geo-locate each hop with IPinfo.
• Store the KMZ and traceroute logs in your POA&M.
• When the auditor shows up, you hand over a thumb drive and smile.

Future Trends: From Fiber to Space and Back

Starlink and OneWeb grab headlines, but DoD still leases fiber because you cannot jam a wet strand of glass. That said, the next fight will be hybrid. Low-Earth-orbit constellations will act as the fail-over when cables are cut on purpose. OSINT analysts should start collecting:

• Starlink gateway coordinates (they are in FCC filings).
• OneWeb ground-segment RFPs (public on Sam.gov).
• ITU satellite beam footprints to see which islands stay lit.

Kindi already ingests FCC bulk data; in the graph, gateway nodes connect to cable landing stations. When both go dark you know somebody is planning an island-hopping campaign.

Key Takeaways

• Undersea cable OSINT is legal, cheap, and embarrassingly effective.
• Map first, exploit second, defend third—always in that order.
• Automate with Kindi or drown in CSVs.
• Every NOTMAR, AIS blip, and LinkedIn brag is a sensor. Use it.

FAQ

Q1: Is monitoring submarine cables with OSINT legal?
A: Yes. AIS, NOTMAR, and public webcams are open data. Avoid hacking or jamming; stay in the open source layer.

Q2: How fast can OSINT detect a cable fault?
A: Within minutes if you automate AIS disappearances and BGP withdrawals.

Q3: Do I need classified feeds to brief DoD?
A: No. We briefed PACAF using only unclassified KMZ and traceroute logs—saved them a 2-week satellite lease.

Q4: What is the cheapest tool to start with?
A: Google Earth plus the free Submarine Cable Map KML. Zero dollars, instant results.

Q5: How does Kindi differ from Maltego?
A: Kindi is cloud-native, API-first, and purpose-built for defense teams. It auto-updates AIS, NOTMAR, and social feeds without manual transforms.
