Smartphone Security: You'll Never Guess Who Just Messaged You
I really don't get the security model for smartphones. It seems horribly brittle. I mean, the fundamental protection is using apps from trusted sources, basically Google or Apple. Anything not trusted can't install, unless you've rooted the phone. And so old-school Windows-style malware is blocked.<p>However, when trusted apps are installed, they often demand all sorts of privileged access. And if they're malicious, there's no way to protect against them. Except that they get reported to Google/Apple and become unavailable. But that doesn't help people who already got pwned.<p>What am I missing?
