Apple has always been meant to want private devices and applications. Privacy is something that the company places great emphasis on. In fact, recently he published how they treated user data. Now we get the news that emails on our Mac will be even more secure and private.
It will be more encrypted because apparently it was not or at least not to the extent that Apple had established until now. That is why they will remedy this situation and get down to work.
The emails in macOS were not as encrypted as we thought
The big problem was detected on the basis of certain macOS database files of some applications, then used by Siri, which also obtained information from it in order to be more functional for the user. An unencrypted information container was detected.
That is, sensitive information was being stored in a database and unencrypted. In addition, this problem occurred not only in macOS Catalina, one more problem to add, yes, I know gave in all previous versions.
This vulnerability was disclosed to Apple in early July and it was in November that the company responded. He has commented:
This situation probably only affects a small number of people. You need to be using macOS, Apple Mail, sending encrypted emails from Apple Mail, not using FileVault to encrypt your entire system anymore, and know exactly what in Apple's system files to be looking for this information. If you were a hacker, you would also need access to those system files.
Now, if you want to prevent emails from being collected in that unencrypted container, you can do the following: System Preferences> Siri> Siri Suggestions and Privacy> Mail and disable "Learn from this application." We can do the same for the other applications. For it In macOS Catalina we must avoid giving applications full access to the disk.
A more drastic solution, but one that works very well and recommended by Apple itself, is that you can enable FileVault. This will encrypt everything on your Mac, if you want to be more secure.
