Shodan: Search Engine for Internet-Connected Devices
Discover internet-connected devices with Shodan, a powerful search engine that filters by location, ports, banners and more, providing visibility into Internet-facing devices and services.
What is Shodan?
Shodan is a search engine for finding Internet-connected devices and services. Unlike traditional search engines that index the content of web pages, Shodan specifically targets hardware and software that is connected to the Internet, ranging from home routers and webcams to industrial control systems and SCADA devices.
Some key features and capabilities of Shodan include:
- Search Internet-connected devices by country, city, IP address, port, banners, and more
- Identify vulnerabilities and misconfigurations in Internet-facing systems
- Gather intelligence on competitors' Internet assets and exposure
- Monitor Internet-connected systems for signs of compromise
- Research specific embedded devices, software platforms, and protocols
- Uncover hidden industrial control systems and SCADA networks
- Analyze Internet usage statistics and adoption trends over time
Shodan helps security professionals, researchers, and businesses understand their attack surface and monitor Internet-connected assets. However, it also aids adversaries in discovering Internet-accessible systems to target for cyber attacks. Users must carefully evaluate the risks and implications of certain search queries. Implementing security best practices is critical to prevent Shodan mapping from inadvertently exposing critical infrastructure or sensitive systems.
