About Shodan free
Account, users are able to search for free on Shodan.io, but some filters and functions are unavailable for free users. Shodan has 4 accounts available, from more affordable personal plans to costly enterprise plans with a large catalogue of advanced benefits.The most basic Shodan searches will give you results by country, network, ports, and operating systems. You can also use filters in your queries to narrow your search: for example, if you want to see how many Cisco devices there are in Miami, you would search “Cisco city:Miami”. Your search can be as simple as this, or if you are more technically inclined, you can employ a more sophisticated search method like SafetyDetectives did to uncover a major security breach found in hospital and supermarket refrigeration systems.Is Shodan legal?Yes! Shodan merely gathers information that’s already publicly available for reference purposes. Shodan doesn’t secretly gather information it isn’t allowed to have. Instead, it collects information already available on the internet.Although news outlets were quick to label Shodan as a part of the “dark web”, Shodan is a perfectly legitimate website that has many benefits — there are hacker tools similar to Shodan that aren’t publicly available, so Shodan actually helps to “even the playing field” between hackers and IT professionals.

Shodan?Shodan is a search engine similar to Google.But while Google searches for websites, Shodan searches for devices that are connected to the internet. Users can perform a search using the Shodan search engine based on an IP address, device name, city, and/or a variety of technical categories. Users can sign up for free accounts, but they are very limited — Shodan limits its free service to only 50 search results.Shodan started in 2003 as a pet project for a young computer programmer, John Matherly. Matherly figured out a way to map each device connected to the internet by constantly crawling the web for randomly generated IP addresses, and he eventually developed a search engine to search through his growing database of internet-connected devices. Matherly released Shodan to the public in 2009.Matherly’s intention was never to create an easy way for hackers to discover devices and infiltrate them, but as soon as Shodan was up and running, it began discovering industrial supervisory control and data acquisition (SCADA) systems, security cameras, traffic lights, and other sensitive devices that shouldn’t have been publicly accessible.Once Matherly discovered how many devices were exposed online, he began marketing Shodan to IT workers to help them analyze and troubleshoot network vulnerabilities.Note: Home networks aren’t especially susceptible to this kind of port crawling, but if you want to keep your devices as secure as possible, you should use an advanced antivirus like Norton that can map out every device on your network and warn you of suspicious connections.How
