Introduction
Shodan is a powerful tool for discovering internet-connected devices, often referred to as the “search engine for hackers,” but its applications extend far beyond malicious use. It indexes devices and the services they expose to the internet, making it an invaluable resource for security researchers, penetration testers, and IT professionals. The Shodan API enhances this functionality by allowing developers to automate searches, monitor devices in real-time, and integrate Shodan’s capabilities into custom tools or workflows. By leveraging Python, a widely-used programming language, you can streamline the process of identifying vulnerabilities in exposed systems.
