@rosyna So you’re saying that the reason the Mac App Store requires sandboxing is to protect against Flash, which most apps don’t use?
Rosyna Keller ‏@rosyna Feb 15

@mjtsai No, it's to prevent bugs in the apps from being exploited and doing harm to other parts of the system.

Rosyna Keller ‏@rosyna Feb 15

@mjtsai The bugs are in the apps. The malicious code is delivered multiple ways. Wikipedia has an article on RCE. https://en.wikipedia.org/wiki/Arbitrary_code_execution …

@rosyna @mjtsai Or touch that file or whatever. But notice that Spotify isn't malicious, in the example it's hijacked and becomes malicious

@rosyna @drewthaler Even for things that would never be approved in the Mac App Store, so that every Developer ID app can be sandboxed.
Rosyna Keller ‏@rosyna Feb 15

@mjtsai @drewthaler That's exactly how sandboxing works today on Mac OS X.

@rosyna @drewthaler If you’re referring to the big red button, that doesn’t sound like something that should be relied on.
Rosyna Keller ‏@rosyna Feb 16

@mjtsai @drewthaler What big red button?
