First Security Breach In The App Store
It looks like the Judgment Day for iOS has finally arrived. Until today the robustness of the AppStore has always been considered one of the strengths of the Apple Model: unlike the Android Market, which is constantly under attack for its weak security model that allowed too many malicious users to upload malicious applications, a strict control policy had prevented, at least so far, the same destiny for the mobile Apple Application.
Unfortunately Charlie Miller, an old acquaintance of the Apple Supporters, thought that winning three Pwn2Owns in the last four years (2008, 2009 and 2011) exploiting practically every Apple Vulnerability was not enough. So he decided consequently to attack Cupertino directly inside its AppStore security model.
The story begins early last year, after the release of iOS 4.3 when the researcher became suspicious of a possible flaw in the code signing of Apple’s mobile devices.
As stated in the original article by Forbes:
The next step was to discover a bug that allowed to expand that code-running exception to any application, and that is exactly what he did, but still this was not enough.
After discovering the bug, he submitted an App to the App Store exploiting the vulnerability. The App was approved and behaved as expected (actually a behaviour to which the victims of Android malware are quite familiar): the app was able to phone home to a remote computer downloading new unapproved commands onto the device and executing them at will, including stealing the user’s photos, reading contacts, making the phone vibrate or play sounds, or otherwise repurposing normal iOS app functions for malicious ends.
This method will be presented at the SysCan Conference in Taiwan next week even if a video demonstrations of the exploit is already available.
Last but not least: as a reward for discovering the bug, Apple has decided to revoke to Miller the Developer’s License.
Probably Android users will be the happiest to learn that, as stated by Miller:
Android has been like the Wild West. And this bug basically reduces the security of iOS to that of Android.
At least for one thing (security), iOS and Android are identical.
