I agree, it's very poorly written.

"These attacks" are defined as "automated exploitation of computer networks that aims to extract cash from the owner of that network" and "cryptocurrency" is "the singular reason" why "these attacks" are "even possible."

Later on the author shamelessly tries to shift that definition to "modern ransomware" (the same trick you're attempting here).

Why do they need to resort to that? Because they're wrong.
