Shodan & Maltego

Shodan and Maltego are core OSINT tools used for technical and analytical intelligence gathering. Shodan focuses on identifying internet exposed systems and services, while Maltego specializes in linking and visualizing relationships between different data points. Together they form a powerful foundation for infrastructure focused OSINT and intelligence correlation. This module is suitable for beginner to intermediate learners and introduces both tools as complementary parts of a single investigative workflow.

What Is Shodan?

Shodan is a search engine designed to index devices and services connected to the internet rather than traditional web content. It scans public IP address ranges and collects information such as open ports, service banners, software versions, SSL certificates, and metadata related to exposed systems. Shodan shows what is visible to anyone scanning the internet and provides insight into how systems are configured and presented externally.

From an OSINT perspective, Shodan answers questions related to exposure and visibility. It helps analysts understand what infrastructure exists, where it is located, and how it is configured based solely on publicly available information.
