Shodan, launched in 2009 by John Matherly, is a search engine that scans the internet for publicly accessible devices, including webcams, routers, and servers. It collects data on IP addresses, open ports, service banners, and software versions, making it a valuable tool for cybersecurity professionals, penetration testers, and researchers. By identifying devices exposed to the internet, Shodan helps organizations assess their security posture and implement necessary protections. en.wikipedia.org
However, Shodan's capabilities also pose risks. Cybercriminals can exploit the information it provides to locate vulnerable systems. For instance, a group of ethical hackers discovered various devices, such as smart home control panels and industrial control systems, exposed on the internet without proper authentication. This highlights the importance of securing devices and networks to prevent unauthorized access. blog.bournemouth2600.org
