Hi Guys,

Android Attacks (Bas Alberts/Massimiliano Oldani),

Perhaps I'm reading Slide 15 wrong:

    Fine grained Permission/Capability model
        ● Per installed Application (Manifest)
        ● Per URI (Intent permission flags)

I believe Android lacks Fine Grained permissions:

Felt, Adrienne Porte; Chin, Erika; Hanna, Steve; Song, Dawn; Wagner,
David. "Android Permissions Demystified,"
Jeon, Jinseong; Micinski, Kristopher K.; Vaughan, Jeffrey A.; Reddy,
Nikhilesh; Zhu, Yixin; Foster, Jeffrey S.; Millstein, Todd." Dr.
Android and Mr. Hide: Fine-grained security policies on unmodified
Android," http://www.cs.umd.edu/~jfoster/papers/acplib.pdf.

In fact, the permissions are so coarse grained and borked that Google
was giving everone READ_PHONE_STATE whether they wanted it or not (the
practice has been changed). And READ_PHONE_STATE  includes call
status, incoming number, identity iformation such as IMSI, etc. See
"Android permissions: Phone Calls: read phone state and identity,"
