idb – iOS App Security Assessment Tool

by Unallocated Author

idb a tool to simplify some common tasks for iOS app security assessments and research.



  • Ubuntu or OS X
  • Ruby 1.9.3 or 2.1


For OS X:

brew install qt cmake usbmuxd libimobiledevice


For Ubuntu:

apt-get install cmake libqt4-dev git-core libimobiledevice-utils libplist-utils usbmuxd libxml2-dev libsqlite3-dev -y


Installing idb:

For production use

  • Install idb: gem install idb
  • Run idb: idb

For development use

  • 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 idb

Note: Running bin/idb directly won’t work since it will not find the idb gem . Instead, the bundle exec command runs idb in the current bundler environment where bundler supplies the gem from source.
