Imagine having a supercharged search engine that lets you find:

• Exposed databases accidentally left open
• Misconfigured APIs are leaking sensitive data
• Industrial control systems (ICS) connected to the internet

That’s FOFA — a cyberspace mapping tool used by ethical hackers, researchers, and cybersecurity teams to discover vulnerabilities before the bad guys do.

But here’s the catch: With great power comes great responsibility.

This guide will show you how to use FOFA like a pro — without breaking any laws.

Why FOFA Beats Shodan & Censys for Security Research

FOFA isn’t just another OSINT tool — it’s the best-kept secret for deep reconnaissance.

Here’s why:

✔ 10+ billion indexed assets (more than some competitors)

✔ Specializing in ICS/OT devices (critical for industrial security)

✔ Strong presence in Chinese networks (where Shodan has blind spots)
