Jailbreaking is the process of exploiting a vulnerability in the iOS device which then provides the user with access to the underlying system with the highest privileges. This means that an attacker has full access to all stored data (data-at-rest), data that is sent and received (data-in-transit) and the filesystem.
When jailbreaking with Checkra1n it will automatically install usbmuxd on the host device but will not include iproxy for this reason it may be required to install libusbmuxd-tools from the apt repositories.


On Linux it is easy to Jailbreak an iOS device using Checkra1n, assuming device is running an exploitable version of iOS. The following URL is the official Checkra1n site: https://checkra.in/​

On Debian-based distros (Ubuntu, Linux Mint, etc.)

The recommended installation method on Debian based systems is our APT repo. This allows for easy updates and management of the checkra1n app.

Using the repo

echo 'deb https://assets.checkra.in/debian /' | sudo tee /etc/apt/sources.list.d/checkra1n.list
sudo apt-key adv --fetch-keys https://assets.checkra.in/debian/archive.key
sudo apt-get update
sudo apt-get install checkra1n
