    If you have a premium Shodan[0] account, they have an ‘Images’ view which is filtered VNC and other Remote Desktop screenshots and links to view them directly with the IP. Lots of security cameras, some SCADA industrial access control... - Source: Hacker News / 6 months ago

    I'm a little surprised you're asking this but as you don't know - if you set the rulebase correctly, you won't get hammered by "public". A lot of people (of course not people here) don't do that which is why shodan.io is full of servers... Source: about 3 years ago
