[Introspy] Monitor app in your iDevice

The Problem

In 2013, assessing the security of iOS applications still involves a lot of manual, time-consuming tasks - especially when performing a black-box assessment. Without access to source code, a comprehensive review of these application currently requires in-depth knowledge of various APIs and the ability to use relatively complex, generic tools such as Cycript, or Mobile Substrate - or just jump straight into the debugger.

To simplify this process, we are releasing Introspy - an open-source security profiler for iOS. Introspy is designed to help penetration testers understand what an application does at runtime.

How Introspy works

The tool comprises two separate components: an iOS tracer and an analyzer.

The iOS tracer can be installed on a jailbroken iOS device. It will hook security-sensitive APIs called by a given application, including functions related to cryptography, IPCs, data storage / protection, networking, and user privacy. The call details are all recorded and persisted in a SQLite database on the device.

This database can then be fed to the Introspy analyzer, which generates an HTML report displaying all recorded calls, plus a list of potential vulnerabilities affecting the application.


Once installed, the tracer will store in a SQLite database all calls made by iOS applications to security-sensitive APIs.
