Let's break down these files.
iOS-- iOS has IPA files.
And these are difficult to decipher.
They're not difficult to open or examine.
They're essentially just TAR files
that you can right-click and do show package contents on a Mac.
However, once you're inside of that application,
that's where things get interesting.
I personally, have not had access to legitimate iOS
Malware to tear apart and examine.
Even in the investigation that I told you
that Lee and I were working on the iPhone,
we couldn't get a full file system extraction.
And you'll see here that you need full file system access
in order to get access to the .ipa file.
So if you don't have that, if you only
have an encrypted iTunes backup or an advanced logical,
even if you think you found the Malware,
you will navigate to the point where you can just
right-click, show package contents on a Mac,
and examine it.
