Adversary infrastructure — the C2 servers, phishing kits, and malware staging behind every attack — can be mapped from a single clue using internet intelligence. This guide shows how researchers do it, with real published cases.
Every cyber attack leaves infrastructure clues on the public internet. This guide explains how investigators pivot from one malicious indicator to an entire attacker network — and why attribution must never rest on a single clue.
You cannot defend what you cannot see. Internet intelligence maps a defense organization's exposed attack surface — and the July 2026 water-sector attacks showed what happens when defenders fall behind.
Thousands of industrial control systems are reachable from the internet. How internet scan data helps defenders find exposed critical infrastructure before attackers do.
Cyber operations in the Russia-Ukraine war run on infrastructure — servers, certificates, domains, and compromised devices that leave traces on the public internet. This article explains the tracking methodology researchers use to find and monitor it, with documented cases from the FBI's Cyclops Blink disruption to CERT-UA's infrastructure investigations.
The Israel–Iran cyber war runs alongside the 2026 conflict — wiper attacks, exposed industrial controllers, and hacktivist DDoS waves. Here is what internet intelligence reveals about the digital front, and how researchers track it.
U.S. agencies confirmed Iranian-affiliated hackers are exploiting internet-exposed PLCs in water, energy, and government sectors. Censys research measured the attack surface — 5,219 exposed controllers, most in the U.S. — and showed how scan data helps defenders fight back.
How threat-intelligence analysts use internet-wide scan data to study cyber warfare: certificate pivoting, infrastructure baselining, reuse tracking across threat reports, and the hard limits of what scan data can prove. Real case studies from Censys research and documented investigations.
