You Should Know:
OSINT is crucial for ICS/OT security professionals to gather threat intelligence. Below are key commands, tools, and steps to practice OSINT techniques in cybersecurity:
1. Basic Linux OSINT Commands
WHOIS lookup for domain info whois example.com DNS enumeration dig example.com ANY nslookup example.com Extract metadata from files exiftool filename.pdf
2. Advanced OSINT Tools
- Maltego – For graphical link analysis
- theHarvester – Email & domain reconnaissance
theHarvester -d example.com -b google
- Shodan – Search for exposed ICS/OT devices
shodan search "Industrial Control Systems"
3. Windows-Based OSINT Commands
Network discovery nslookup example.com netstat -ano | findstr LISTENING Extract file hashes for threat intel certutil -hashfile malware.exe SHA256
4. Practical OSINT Steps for ICS/OT Security
1. Identify Publicly Exposed ICS Devices using Shodan/Censys.
2. Analyze Threat Feeds (e.g., MISP, OTX AlienVault).
- Track Threat Actors via Twitter, GitHub, and dark web forums.
- Use OSINT Frameworks like SpiderFoot or OSINT Framework.
What Undercode Say:
OSINT is a foundational skill for ICS/OT cybersecurity. Mastering tools like Maltego, Shodan, and theHarvester enhances threat detection. Always verify findings with multiple sources and stay updated with ICS-CERT advisories.
