Cloud_Enum – Multi-cloud OSINT Tool. Enumerate Public Resources In AWS, Azure, And Google Cloud

Multi-cloud OSINT tool. Enumerate public resources in AWS, Azure, and Google Cloud.

Currently enumerates the following:

Amazon Web Services: – Open / Protected S3 Buckets – awsapps (WorkMail, WorkDocs, Connect, etc.)

Microsoft Azure: – Storage Accounts – Open Blob Storage Containers – Hosted Databases – Virtual Machines – Web Apps

Google Cloud Platform – Open / Protected GCP Buckets – Open / Protected Firebase Realtime Databases – Google App Engine sites – Cloud Functions (enumerates project/regions with existing functions, then brute forces actual function names) – Open Firebase Apps

See it in action in Codingo‘s video demo here.

Setup

Several non-standard libaries are required to support threaded HTTP requests and dns lookups. You’ll need to install the requirements as follows:

pip3 install -r ./requirements.txt

Running

The only required argument is at least one keyword. You can use the built-in fuzzing strings, but you will get better results if you supply your own with -m and/or -b.

You can provide multiple keywords by specifying the -k argument multiple times.

Keywords are mutated automatically using strings from enum_tools/fuzz.txt or a file you provide with the -m flag. Services that require a second-level of brute forcing (Azure Containers and GCP Functions) will also use fuzz.txt by default or a file you provide with the -b flag.

Let’s say you were researching “somecompany” whose website is “somecompany.io” that makes a product called “blockchaindoohickey”. You could run the tool like this:

./cloud_enum.py -k somecompany -k somecompany.io -k blockchaindoohickey

HTTP scraping and DNS lookups use 5 threads each by default. You can try increasing this, but eventually the cloud providers will rate limit you. Here is an example to increase to 10.

./cloud_enum.py -k keyword -t 10

IMPORTANT: Some resources (Azure Containers, GCP Functions) are discovered per-region. To save time scanning, there is a “REGIONS” variable defined in cloudenum/azure_regions.py and cloudenum/gcp_regions.py that is set by default to use only 1 region. You may want to look at these files and edit them to be relevant to your own work.

Complete Usage Details

usage: cloud_enum.py [-h] -k KEYWORD [-m MUTATIONS] [-b BRUTE]

Multi-cloud enumeration utility. All hail OSINT!

optional arguments:

Keyword. Can use argument multiple times.
-kf KEYFILE, --keyfile KEYFILE
Input file with a single keyword per line.
-m MUTATIONS, --mutations MUTATIONS
Mutations. Default: enum_tools/fuzz.txt
-b BRUTE, --brute BRUTE
List to brute-force Azure container names. Default: enum_tools/fuzz.txt
-t THREADS, --threads THREADS
Threads for HTTP brute-force. Default = 5
-ns NAMESERVER, --nameserver NAMESERVER
DNS server to use in brute-force.
-l LOGFILE, --logfile LOGFILE
Will APPEND found items to specified file.
-f FORMAT, --format FORMAT
Format for log file (text,json,csv - defaults to text)
--disable-aws Disable Amazon checks.
--disable-azure Disable Azure checks.
--disable-gcp Disable Google checks.
-qs, --quickscan Disable all mutations and second-level scans
