@silent Either what you say in this thread about the content of the book is representative, or you're overselling it. If you're overselling it here, why should one trust what's in it? If this is representative, then the book is clearly exaggerating because there is no such thing as "unbreakable" anything. (Harder to break? Yes. Secure enough? Sure. But unbreakable? Big fat no.)#iMessage #vulnerability #security #iOS #cybersecurity
