FindMy

Query Apple's Find My network, allowing none Apple devices to retrieve the location reports.

This project based on all the hard work of, and is a combination of the following projects:

  1. https://github.com/seemoo-lab/openhaystack/
  2. https://github.com/biemster/FindMy
  3. https://github.com/Dadoum/anisette-v3-server
  4. https://github.com/mrmay-dev/owntags

Schematic and Usage

generate_keys.py

Use the generate_keys.py script to generate the required keys. The script will generate a .keys or multiple files for each device you want to use. Each .keys file will contain the private key, the public key (also called advertisement key) and the hashed advertisement key. As the name suggests, the private key is a secret and should not be shared. The public key (advertisement key) is used for broadcasting the BLE message, this is also being asked by the hci.py script in openhaystack project. The hashed advertisement key is for requesting location reports from Apple.

request_reports.py

Use the request_reports.py script to request location reports from Apple. The script will read the .keys files and request location reports for each device. The script will also attempt to log in and provided Apple account and save the session cookies in auth.json file. The reports are stored in the reports database.

web_service.py

Use the web_service.py script to start a web service that will serve the location reports via its API.

anisette-v3-server

Q: What does this external project do? The SMS code is only asked once, in where and how is the information stored?

A: Anisette is similar to a device fingerprint. It is intended to be stored on an Apple device once it becomes trusted. Subsequent requests made by this "device" using this fingerprint and same Apple account will not trigger the 2FA again. The first call (icloud_login_mobileme) is used to obtain the search party token. The subsequent calls (generate_anisette_headers) use the cached search party token from the first call as the password and the dsid as the username. I (@biemster) have observed that the search party tokens change when using different sources for anisette data, possibly due to various reasons. If it's deployed as a docker container, the storage location is $HOME/.config/anisette-v3/ adi.pb and device.json. These numbers together generate a validation code like OTP, which then undergoes a process of Mixed Boolean Arithmetic to produce two anisette headers for the request. One header represents a relatively static machine serial, while the other header contains a frequently changing OTP. If you switch to https://github.com/Dadoum/pyprovision, you will obtain the ADI data in the anisette folder. (Answer revised and organized from biemster#37 (comment))

Installation and initial setup

This project only need a free Apple ID with SMS 2FA properly setup. If you don't have any, follow one of the many guides found on the internet.

Using your personal Apple ID is strongly discouraged, I recommended to create a blank Apple ID for experimental purpose. If you ran into issue of "KeyError service-data", especially you are using an existing account rather than a new account, you may want to refer to #9 .

📺 Installation and Walkthrough Video: https://youtu.be/yC2HIPDSxlM

Steps

  1. Install docker and Python3-pip. How to Install Docker on Ubuntu. Python3-venv is also strongly recommended.

  2. The anisetter service shall run on the same device of this project. For Linux system, deploy with docker is recommended. If the system rebooted, this docker service will automatically start after reboot.

docker run -d --restart always --name anisette-v3 -p 6969:6969 dadoum/anisette-v3-server:latest

If docker method didn't work, see the end of this section for manual setup.

  1. After deployed anisette-v3-server, you may validate the service is running by sending a curl request:
curl -I http://localhost:6969
  1. Clone this repository, Navigate to FindMy directory, and install the required python packages:
git clone https://github.com/Chapoly1305/FindMy.git
cd FindMy
pip3 install -r requirements.txt

The anisette-v3 docker image shall be available for x86, x86-64, arm, and arm64. In case of the docker container is not available, you may start it by setup anisette-v3-server manually. Follow the installation instructions for anisette-v3-server project.

Run

You may run this project as a local service, a web service, or both.

Key generation

./generate_keys.py # Without any arguments, it will generate a single key file and save under current directory.

Deploy your advertisement keys on devices supported by OpenHaystack. The ESP32 firmware is a mirror of the OpenHaystack binary, the Lenze 17H66 is found in many 1$ tags obtained from Ali. An nRF51 firmware can be found here: https://github.com/dakhnod/FakeTag

as a local service and write to database

The anisetter docker service shall run on the same device of this project. If the anisetter has started, then run:

./request_reports.py # Without any arguments, it will read all the .keys files under current directory.

as a web service

You are advised to configure adequate firewall rules to protect the web service.

To run as a web service, firstly install uvicorn by

pip3 install uvicorn

then run

uvicorn web_service:app --reload

or

./web_service.py

The difference between the two commands is that the first one will reload the web service when the source code is changed. Each time the web_service.py is modified and saved, the web service will auto reload. Quite useful for development.

This web service will die if the shell exited or system reboot. You could use nohup, screen, or set up a systemd service to keep it alive.

nohup uvicorn web_service:app --reload &


API Usage

The APIs are created with FastAPI, the documentations are written inline and can be accessed on website path http://127.0.0.1:8000/docs or http://127.0.0.1:8000/redoc. The project is currently under development, which may lead to frequent changes of the APIs. Please use with cautious.
