Basically, it boils down to time-sensitive vulnerabilities (aka zero-day).

Only can only be used a very few times or once (before someone discovers it and covers it up).

This threat has been already been an ongoing and recurring events (that the author apparently has totally overlooked) and repeatedly pointed out by may research papers.

No, the author apparently did NOT sufficiently research this topic and I'm claiming he did not research AT ALL.
