  1. Shodan API You can think of Shodan as Google for every device connected to the internet. They crawl the web and catalog devices. You can sign up for a developer account and programmatically access their data and filter based on numerous factors. Some things people have found exposed and unsecured on Shodan:
  • A French hydroelectric plant control system
  • entire cities transportation grids
  • databases
  • industrial freezers with 10's of thousands of dollars in goods
  • car washes that can be remotely shut down

With Shodan you are really only limited by your imagination, just make sure you don't get yourself arrested.

Conclusion

If you think I forget any APIs let me know. Also I'd love to see people brainstorming cool ideas in the comments below.
