[Introspy] Security profiling for blackbox iOS

Thursday, February 13, 2014

Blackbox tool to help understand what an iOS application is doing at runtime and assist in the identification of potential security issues.

The tracer can be installed on a jailbroken device to hook and log security-sensitive iOS APIs called by applications running on the device. The tool records details of relevant API calls, including arguments and return values and persists them in a database. Additionally, the calls are also sent to the Console for real-time analysis.

How Introspy works

The tool comprises two separate components: Introspy-iOS and Introspy-Analyzer.

Introspy-iOS is a tracer that 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 Introspy-Analyzer, which generates an HTML report displaying all recorded calls, plus a list of potential vulnerabilities affecting the application.
