      Apple has a unique capability to respond to these issues. They can patch and users apply it. Discovery means the technique dies immediately.

      As usual, neither report contains *any* detailed analysis of the exploits, only the malware payload. The skills to do so are too uncommon.

      Important to note: The NSO exploit chain DID NOT include a sandbox escape. This means their kernel exploits were good enough w/o one.

      The lack of exploit analysis skill has consequences. No IOCs for pre-compromise detections. You have to wait until you get 0wned to find it.

      People wondering why I'm not surprised: Amateurs produce iOS jailbreaks once a year (Pangu et al). Professionals won't be any less skilled.

      People asking abt iOS10: Unlikely that existing toolkit works out of the box on 10. Even if underlying vulns still present, kit prob broken.

          Absolutely true. 9.3.5 protects you from NSO customers, and expected copycat attacks once exploits become public. iOS10 more meaningful.

          The exploit developer, though, would know what to look for in iOS 10; so unfixed vulns will be re-found, possibly quickly.

          there are new exploit mitigations and more code deprecated in every major release. Not a guaranteed.
