I read a bunch of it. Looks like a typical “white paper” released by a security contractors to impress upper management types. It appears to say a lot but doesn’t really say that much.

Correct. It was a copy and paste job by an FBI intern. I recognize much of the language from other similar "reports" from various consulting firms and Windows / Linux / Unix Systems Administration & Security 101 books.

Any script kiddie can do it.
