[*]

Graphicator is a GraphQL “scraper” / extractor. The tool iterates over the introspection document returned by the targeted GraphQL endpoint, and then re-structures the schema in an internal form so it can re-create the supported queries. When such queries are created is using them to send requests to the endpoint and saves the returned response to a file.

Erroneous responses are not saved. By default the tool caches the correct responses and also caches the errors, thus when re-running the tool it won’t go into the same queries again.

Use it wisely and use it only for targets you have the permission to interact with.

We hope the tool to automate your own tests as a penetration tester and gives some push even to the ones that don’t do GraphQLing test yet.

Installation

Install on your system

python3 -m pip install -r requirements.txt

Using a container instead

docker run --rm -it -p8005:80 cybervelia/graphicator --target http://the-target:port/graphql --verbose

When the task is done it zips the results and such zip is provided via a webserver served on port 8005. To kill the container, provide CTRL+C. When the container is stopped the data are deleted too. Also you may change the host port according to your needs.

Usage

python3 graphicator.py [args...]

Setting up a target

The first step is to configure the target. To do that you have to provide either a --target option or a file using --file.

Setting a single target via arguments

python3 graphicator.py --target https://subdomain.domain:port/graphql

Setting multiple targets

python3 graphicator.py --target https://subdomain.domain:port/graphql --target https://target2.tld/graphql

Setting targets via a file

python3 graphicator.py --file file.txt

The file should contain one URL per line as such:

http://target1.tld/graphql
http://sub.target2.tld/graphql
http://subxyz.target3.tld:8080/graphql

Using a Proxy

You may connect the tool with any proxy.

Connect to the default burp settings (port 8080)

python3 graphicator.py --target target --default-burp-proxy

Connect to your own proxy

python3 graphicator.py --target target --use-proxy

Connect via Tor

python3 graphicator.py --target target --use-tor

Using Headers

python3 graphicator.py --target target --header "x-api-key:60b725f10c9c85c70d97880dfe8191b3"

Enable Verbose

python3 graphicator.py --target target --verbose

Enable Multi-threading

python3 graphicator.py --target target --multi

Disable warnings for insecure and self-signed certificates

python3 graphicator.py --target target --insecure

Avoid using cached results

python3 graphicator.py --target target --no-cache

Example

python3 graphicator.py --target http://localhost:8000/graphql --verbose --multi

query {getUsers  { id,username,email,password,level } }

Output Structure

Three folders are created:

• reqcache: The response of each valid query is stored in JSON format
• reqcache-intro: All introspection queries are stored in a separate file in this directory
• reqcache-queries: All queries are stored in a separate file in this directory. The filename of each query will match with the corresponding filename in the reqcache directory that holds the query’s response.

The filename is the hash which takes account the query and the url.
