📰 Latest news

02/10/2020 : Since a few days ago, Google returns a 404 when we try to access someone's Google Photos public albums, we can only access it if we have a link to one of their albums.
Either this is a bug and this will be fixed, either it's a protection that we need to find how to bypass.
03/10/2020 : Successfully bypassed. 🕺 (commit 01dc016)
It requires the "Profile photos" album to be public (it is by default)
20/10/2020 : Google WebArchive now returns a 404 even when coming from the "Profile photos" album, so the photos scraping is temporary (or permanently) disabled. (commit e762543)
25/11/2020 : Google now removes the name from the Google Maps profile if the user has 0 reviews (or contributions, even private). I did not find a bypass for the moment, so all the help in the research of a bypass is appreciated.
20/03/2021 : Successfully bypassed. 🕺 (commit b3b01bc)

Installation

Manual installation

Make sure you have Python 3.7+ installed. (I developed it with Python 3.8.1)
Some Python modules are required which are contained in requirements.txt and will be installed below.

1. Chromedriver & Google Chrome

This project uses Selenium and automatically downloads the correct driver for your Chrome version.
⚠️ So just make sure to have Google Chrome installed.

2. Cloning

Open your terminal, and execute the following commands :

git clone https://github.com/mxrch/ghunt
cd ghunt

3. Requirements

In the GHunt folder, run:

python3 -m pip install -r requirements.txt

Adapt the command to your operating system if needed.

Docker

The Docker image is automatically built and pushed to Dockerhub after each push on this repo.
You can pull the Docker image with:

docker pull mxrch/ghunt

Then, any of the scripts can be invoked through:

docker run -v ghunt-resources:/usr/src/app/resources -ti mxrch/ghunt check_and_gen.py
docker run -v ghunt-resources:/usr/src/app/resources -ti mxrch/ghunt ghunt.py email <email_address>
docker run -v ghunt-resources:/usr/src/app/resources -ti mxrch/ghunt ghunt.py doc <document_link>

Usage

For the first run and sometime after, you'll need to check the validity of your cookies.
To do this, run check_and_gen.py.
If you don't have cookies stored (ex: first launch), you will be asked for the required cookies. If they are valid, it will generate the Authentication token and the Google Docs & Hangouts tokens.

Then, you can run the tool like this:

python3 ghunt.py email larry@google.com

python3 ghunt.py doc https://docs.google.com/spreadsheets/d/1BxiMVs0XRA5nFMdKvBdBZjgmUUqptlbs74OgvE2upms

⚠️ I suggest you make an empty account just for this or use an account where you never login because depending on your browser/location, re-logging in into the Google Account used for the cookies can deauthorize them.

Where I get these cookies ?

Auto (faster)

You can download the GHunt Companion extension that will automate the cookies extraction in 1-click !

You just need to launch the check_and_gen.py file and choose the extraction mode you want to use, between putting GHunt in listening mode, or copy/paste the encoded cookies in base64.

Manual

Be logged-in to myaccount.google.com
After that, open the Dev Tools window and navigate to the Network tab
If you don't know how to open it, just right-click anywhere and click "Inspect Element".
Go to myaccount.google.com, and in the browser requests, select the GET on "accounts.google.com" that gives a 302 redirect
Then you'll find every cookie you need in the "cookies" section.

🛡️ Protecting yourself

Regarding the collection of metadata from your Google Photos account:

Given that Google shows "X require access" on your Google Account Dashboard, you might imagine that you had to explicitly authorize another account in order for it to access your pictures; but this is not the case.
Any account can access your AlbumArchive (by default):

Here's how to check and fix the fact that you're vulnerable (which you most likely are):
Go to https://get.google.com/albumarchive/ while logged in with your Google account. You will be automatically redirected to your correct albumarchive URL (https://get.google.com/albumarchive/YOUR-GOOGLE-ID-HERE). After that, click the three dots on the top left corner, and click on setting

Then, uncheck the only option there:

On another note, the target account will also be vulnerable if they have ever used Picasa linked to their Google account in any way, shape or form. For more details on this, read PinkDev1's comment on issue #10.
For now, the only (known) solution to this is to delete the Picasa albums from your AlbumArchive.

Thanks

This tool is based on Sector's research on Google IDs and completed by my own as well.
If I have the motivation to write a blog post about it, I'll add the link here !
