Foreign hackers breached a US nuclear weapons plant via SharePoint flaws

Hahaha, how stupid must anyone be to deploy SharePoint anywhere near anything of national security relevance! How can it still be a thing, that anyone entrusted with such sensitive matter dates to even touch MS products of the kind of SharePoint? That includes the complete MS Office 365 disaster suite, MS Teams and Edge.

Sounds like they need to seriously redesign their security policies.
