AWS Service Enumeration

Disclaimer

The tool is in beta stage (testing in progress), no destructive API Calls used ( read only actions ). I hope, there will be no issues with the tool. If any issues encountered, please submit the ticket.

Description

The AWS Enumerator was created for service enumeration and info dumping for investigations of penetration testers during Black-Box testing. The tool is intended to speed up the process of Cloud review in case the security researcher compromised AWS Account Credentials.

AWS Enumerator supports more than 600 API Calls ( reading actions Get, List, Describe etc... ), and will be extended.

The tool provides interface for result analysis. All results are saved in json files (one time "Database").

Install

If you have Go installed and configured (i.e. with $GOPATH/bin in your $PATH):

go get -u github.com/shabarkin/aws-enumerator

go install -v github.com/shabarkin/aws-enumerator@latest

Basic Usage

Credentials setup

To setup credentials, you should use cred subcommand and supply credentials:

./aws-enumerator cred -aws_access_key_id AKIA***********XKU -aws_region us-west-2 -aws_secret_access_key kIm6m********************5JPF

It creates .env file, which is loaded to global variables each time you call enum subcommand.

WARNING: If you set these values AWS_REGION, AWS_ACCESS_KEY_ID, AWS_SECRET_ACCESS_KEY, AWS_SESSION_TOKEN in global variables manually before running the tool, it will not be able to load AWS Credentials specified in .env file ( It can't overwrite global variables ).

Enumeration

To enumerate all services, you should use enum subcommand and supply all value or iam,s3,sts,rds ( no spaces between commas ), etc. ...

./aws-enumerator enum -services all

If you want to check specific services (up to 10 ):

./aws-enumerator enum -services iam,sts,rds

(-speed flag is optional, the default value is normal ) There are 3 options slow, normal, fast

./aws-enumerator enum -services all -speed slow

Analysis

To analyse the collected information, you should use dump subcommand: ( Use all for quick overview of available API calls )

./aws-enumerator dump -services all

Analyze specific services (up to 10) iam,s3,sts, etc ...

./aws-enumerator dump -services iam,s3,sts

To filter API calls, you should use -filter option, start typing the name of API call (GetA ...):

./aws-enumerator dump -services iam -filter GetA

To retrieve the result of API call, you should use -print option

./aws-enumerator dump -services iam -filter ListS -print
