pypush

pypush is a POC demo of my recent iMessage reverse-engineering. It can currently register as a new device on an Apple ID, set up encryption keys, and send and receive iMessages!

pypush is completely platform-independent, and does not require a Mac or other Apple device to use!

Installation

It's pretty self explanatory:

1. git clone https://github.com/JJTech0130/pypush
2. If on a Mac, ensure cmake is installed. Otherwise, run brew install cmake
3. pip3 install -r requirements.txt
4. python3 ./demo.py

Troubleshooting

If you have any issues, please join the Discord and ask for help.

Operation

pypush will generate a config.json in the repository when you run demo.py. DO NOT SHARE THIS FILE. It contains all the encryption keys necessary to log into you Apple ID and send iMessages as you.

Once it loads, it should prompt you with >>. Type help and press enter for a list of supported commands.

Special Notes

Unicorn dependency

pypush currently uses the Unicorn CPU emulator and a custom MachO loader to load a framework from an old version of macOS, in order to call some obfuscated functions.

This is only necessary during initial registration, so theoretically you can register on one device, and then copy the config.json to another device that doesn't support the Unicorn emulator. Or you could switch out the emulator for another x86 emulator if you really wanted to.

"data.plist" and Mac serial numbers

This repository contains a sample data.plist, which contains the serial number and several other identifiers from a real Mac device. If you run into issues related to rate-limiting or messages failing to deliver, you may regenerate this file by cloning nacserver and running build.sh on a non-M1 Mac. It should place the generated file in the current directory, which you can then copy to the emulated/ folder in pypush.
