goctopus's Introduction

goctopus

Blazing fast graphql fingerprinting toolbox.

⚠️ Goctopus is still in very early development. Breaking changes are expected.

Usage

Using go:

go install -v github.com/Escape-Technologies/goctopus/cmd/goctopus@latest
goctopus -a example.com

Using docker:

docker run --rm -it escapetech/goctopus:latest -a example.com

Main options & features

It is recommended to use the -a flag as a shorthand to enable all the features (if you want detailed results, and don't care about speed).

Input

Goctopus takes a list of adresses (endpoints and/or urls) as input. Adresses can be specified directly in the command line or in a file.

Command line

The adresses can be specified directly in the command line, comma separated. Example:

goctopus -a example.com,https://example.com/graphql

Input file

The adresses can be specified in a file, one per line. The file path should be specified using the -f flag. Example:

example.com
https://example.com/graphql
escape.tech
https://example.com/api

goctopus -f input.txt

Introspection fingerprinting

The -introspect flag enables introspection fingerprinting. If enabled, goctopus will detect if the introspection of graphql endpoints is enabled.

Subdomain enumeration

The -subdomain flag enables subdomain enumeration. If enabled, goctopus will try to find graphql endpoints on subdomains of the given domains. The enumeration is done using subfinder.

Field suggestion fingerprinting

The -suggest flag enables field suggestion fingerprinting. This option needs the introspection fingerprinting (-introspect) to be enabled. When enabled, goctopus will try to detect if the graphql endpoint has field suggestion enabled, if the introspection is closed. This is useful to bruteforce fields and/or types when introspection is disabled, with tools such as ClairvoyaceNext.

Output

The -o is used to specify the output file path. It defaults to output.jsonl. The output file is in json-lines format. Each line corresponds to one found graphql endpoint and will contain at least the following fields:

{
  "domain": "subdomain.example.com",
  "authenticated": false,
  "url": "https://subdomain.example.com/graphql",
  "source": "example.com"
}

The authenticated field can be one of the following:

true: The endpoint is a graphql endpoint.
false: The endpoint is a graphql endpoint and requires authentication.

Additional options

Usage: goctopus [options] [addresses]
[addresses]: A list of addresses to fingerprint, comma separated.
Addresses can be in the form of http://example.com/graphql or example.com. If an input file is specified, this argument is ignored.
[options]:
  -a	(All) Enable all fingerprinting methods: introspection, field suggestion, subdomain enumeration
  -f string
    	Input file
  -introspect
    	Enable introspection fingerprinting
  -o string
    	Output file (json-lines format)
  -s	Silent
  -subdomain
    	Enable subdomain enumeration
  -suggest
    	Enable fields suggestion fingerprinting.
    	Needs "introspection" to be enabled.
  -t int
    	Request timeout (seconds) (default 30)
  -v	Verbose
  -w int
    	Max workers (default 40)
  -webhook string
    	Webhook URL

Docker usage

Using volumes to load the input file and save to the output file:

docker run --rm -it -v $(pwd):/data escapetech/goctopus:latest -f /data/input.txt -o /data/output.jsonl

Using a specific version:

# for version vA.B.C
docker run --rm -it escapetech/goctopus:A.B.C [args]

I tried again the exact same command and then it worked: I could not reproduce.
