Usage

Generating IPA

Simply generate custom IPA file or patch existing one and install it on target's iPhone or iPad via TrollStore or other IPA installer that bypasses CoreTrust.

Starting listener

Then you will need to start a listener on a host and port you added to your IPA. Once the installed application opens, you will receive a connection.

Accessing device

Once you have received the connection, you will be able to communicate with the session through a Pwny interactive shell. Use devices -i <id> to interact and help to view list of all available commands. You can even extract Safari history like in the example below.

Covering them All

A wide range of iOS versions are supported, being 14.0 beta 2 - 16.6.1, 16.7 RC, and 17.0 beta 1 - 17.0, as these versions are vulnerable to the CoreTrust bug.
