The title pretty much says it. But again. Lets assume you have a government attack on an iphone and they use a spyware of the sophistication level of FinFishers solutions or alike does: Updating to the newest version of ios Hard reset the phone securely remove the spyware? 1) i see more as a bonus question that is not really needed, but might generate useful insights too. I would thank you for a careful but practical answer, since this question relates to some "moving parts" like: "Is it possible to load a "real" update from an infected phone, or will a sophisticated attack redirect those requests" and if there is something you can do to prevent this etc. or the question whether a hard reset really deletes everything or if the spyware can somewhat hide in "blocked" or wrongly addressed areas of the storage and so on. On the other hand i do know that there never is absolute certainty and would be more interested in a "probabilistic view". Thanks to the Forum!
