Idb

idb is a tool to simplify some common tasks for iOS pentesting and research. Originally there was a command line version of the tool, but it is no longer under development so you should get the GUI version.

idb was released as part of a talk at ShmooCon 2014. The slides of the talk are up on Speakerdeck. Video is available on archive.org There is also a blog post on my personal website.

Installation

idb has some prerequisites. As it turns out, things like ruby and Qt are difficult to bundle into a stand-alone installer. While idb itself can easily be installed via Ruby Gems, you need to have some additional software first:

1. Prerequisites

1.1 Ruby Environment

idb requires a valid ruby 1.9.3 or 2.1 installation and it is recommended to install the used ruby using RVM. Ruby 2.0 does not work properly due to issues with qtbindings.

Important Note: Shared library support is required! This is the default for many system rubies, but if you install a ruby via rvm or similar, you need to do one of the following:

• Under rvm use rvm install 2.1 --enable-shared when installing ruby.
• Under ruby-install/chruby use -- --enable-shared when installing ruby.
• Under ruby-build/rbenv with ruby-build use CONFIGURE_OPTS=--enable-shared [command] when installing Ruby.

1.2 Install Other Prerequisites:

• OS X: brew install qt cmake usbmuxd libimobiledevice
• Ubuntu: apt-get install cmake libqt4-dev git-core libimobiledevice-utils libplist-utils usbmuxd -y

2. Installing idb

2.1 Production Use

• Install idb: gem install idb
• Run idb: idb
• Hooray!

2.2 Development

• Clone the repository git clone https://github.com/dmayer/idb
• cd idb
• bundle install (using the right ruby version)
• As for every ruby gem, the application code lives in the lib folder
• Run idb by calling bundle exec rake run
  • Note: Running bin/idb directly won't work since it will not find the idb gem (or use the installed gem and not the checked out source code). Instead, the rake task runs idb in the current bundler environment where bundler supplies the gem from source.

Usage

See the basic manual and walk-through to get started.

New as of October 2014: Idb now stores its configuration and temporary files in ~/.idb/

FAQ

Q: After staring idb, the menu bar does not appear

A: This seems to be a bug when using ruby 2.1 on OS X. I have no idea why this is happening, but switching to a different application and the back to idb fixes it. Any pointers on how to fix this are greatly appreciated!
