My last write-up on smartphone risks applies to this discussion.<p><a href="https:&#x2F;&#x2F;news.ycombinator.com&#x2F;item?id=10906999" rel="nofollow">https:&#x2F;&#x2F;news.ycombinator.com&#x2F;item?id=10906999</a><p>Apple is far from having a secure phone right now. NSA certainly has ways to bypass this based on my attack framework and their prior work. They just don&#x27;t want them to be known. They pulled the same stuff in the past where FBI talked about how they couldn&#x27;t beat iPhones but NSA had them in the leaks &amp; was parallel constructing to FBI. So, the current crop are probably compromised but reserved for targets worth the risk.<p>That said, modifying CPU to enable memory + I&#x2F;O safety, restricting baseband, an isolation flow for hardware, and some software changes could make a system where 0-days were rare enough to be worth much more. Oh yeah, they&#x27;ll have to remove the debugging crap out of their chips and add TEMPEST shielding. Good luck getting either of those two done. ;)
