Just completed a 9-hour live session on OSINT for ICS/OT, covering essential techniques for gathering open-source intelligence in industrial control systems and operational technology environments.
Key Takeaways:
- to OSINT Framework – Understanding methodologies for intelligence gathering.
- Target Discovery – Using traditional and specialized search engines.
- Hands-on Labs – Reconnaissance and enumeration with tools like:
– Sockpuppet (anonymous account creation)
– Email Scraper & Hunter.io (email harvesting)
– Shodan (IoT/OT device discovery)
– Have I Been Pwned & Dehashed (breach data lookup)
– Google Hacking Database (advanced search queries)
– DNSlytics & DNSdumpster (DNS reconnaissance)
– SpiderFoot (automated OSINT collection)
– Infrastructure Mapping & SMAP (network scanning)
4. Crafting OSINT Reports – Structuring findings for actionable intelligence.
5. Real-World OSINT Scenarios – Solving ICS/OT-related investigations.
You Should Know: Practical OSINT Commands & Techniques
1. Shodan for ICS/OT Asset Discovery
Search for exposed PLCs, HMIs, and SCADA systems:
shodan search "port:502" shodan search "SCADA" country:US
2. Google Dorking for ICS Exposures
Find exposed industrial control panels:
inurl:/HMI/index.html intitle:"SCADA" intext:"login" filetype:pdf "PLC configuration" site:org
3. DNS Recon with DNSdumpster
curl -X POST https://dnsdumpster.com --data "target=example.com"
4. Email Enumeration with Hunter.io
hunter.io domain=example.com --api-key YOUR_API_KEY
5. SpiderFoot Automated OSINT
python3 sf.py -s example.com -m all
6. Checking Breached Data
curl https://api.dehashed.com/[email protected] -u API_KEY:
7. Network Scanning with SMAP
smap -iL targets.txt -oA scan_results
What Undercode Say
OSINT is a powerful tool for ICS/OT security, helping identify exposed assets before attackers do. Always:
– Use legal & ethical boundaries in recon.
– Automate with SpiderFoot & Shodan CLI.
– Document findings in structured reports.
– Combine Google Dorks & DNS recon for deeper insights.
For ICS/OT professionals, mastering these techniques enhances threat intelligence and vulnerability management.
Expected Output:
A structured OSINT report containing:
- Exposed ICS/OT devices
- Breached credentials linked to the target
- Network maps from DNS & Shodan scans
- Recommendations for securing identified assets
