This was known, in the past, but if its relying on zero-days Apple & Google are, adversarially, attempting to keep up with and patch, my assumption would
not be that pegasus is, at any time, always able to breach a fully-updated iPhone. Rather, its a situation where maybe there are periods of a few months at a time where they have a working exploit, until Apple discovers it and patches it, repeat indefinitely.
