mr-exo/HikvisionBackdoor ? reverse-engineered prompt

Build me a small Python tool that uses Shodan to find Hikvision camera IPs and then checks whether they’re vulnerable to that known backdoor. I want it to be simple to run from one script, take my Shodan API key and any search filters as input, then print out the IPs it finds and clearly show which devices look exposed.

Make the output easy to read, with the vulnerable targets highlighted and a short summary at the end. If you can, add a basic way to save the results to a file too. Keep it straightforward and close to the original idea of a quick scanner, not a big app.

If you need to look up current Shodan or Hikvision details to make the checks accurate, go ahead and use the latest docs online.
