The articles covers how you can consume indicators of compromise (IOC) received via manual sharing. Although automatic sharing is preferred not all organisations have the resources to setup automatic sharing. Manual sharing is then a good fallback compared to not sharing at all.

I wrote a script that takes one parameter (ideally a string) and
