What does Aaia do?
Aaia (pronounced as shown here) helps in visualizing AWS IAM and organizations in a graph format with help of Neo4j. This helps in identifying the outliers easily. Since it is based on neo4j , one can query the graph using cypher queries to find the anomalies.
Aaia also supports modules to programatically fetch data from neo4j database and process it in a custom fashion. This is mostly useful if any complex comparision or logic has to be applied which otherwise would not be easy through cypher queries.
Aaia was initially intended to be a tool to enumerate privelege esclation possibilities and find loop holes in AWS IAM. It was inspired from the quote by @JohnLaTwC
"Defenders think in lists. Attackers think in graphs. As long as this is true, attackers win."
Why the name "Aaia"?
Aaia in Tamil means grandma. In general, Aaia knows everything about the family. She can easily connect who is related to whom and how and give you the connection within a split second. She is a living graph database!
Since "Aaia" also does more or less the same, hence the name.
Install the neo4j Database
Setup the username, password and bolt connection uri in Aaia.conf file. An example format is given in Aaia.conf file already.
Install OS dependency
apt-get install awscli jq
Redhat / Fedora / Centos / Amazon Linux :
yum install awscli jq
These packages are needed for Aaia_aws_collector.sh script. Ensure these packages are present in the base system from where the collector script is being run.
Clone this repository
git clone https://github.com/rams3sh/Aaia cd Aaia/
Create a virtual environment
python3 -m venv env
Activate the virtual environment
Note: Aaia depends on pyjq library which is not stable in windows currently. Hence Aaia is not supported for Windows OS.
Install the dependencies
python -m pip install -r requirements.txt
Setting up Permissions in AWS
Aaia would require following AWS permissions for collector script to collect relevant data from AWS
iam:GenerateCredentialReport iam:GetCredentialReport iam:GetAccountAuthorizationDetails iam:ListUsers iam:GetUser iam:ListGroups iam:ListRoles iam:GetRole iam:GetPolicy iam:GetAccountPasswordPolicy iam:GetAccountSummary iam:ListAccountAliases organizations:ListAccountsForParent organizations:ListOrganizationalUnitsForParent organizations:DescribeOrganization organizations:ListRoots organizations:ListAccounts organizations:ListTagsForResource organizations:ListPolicies organizations:ListTargetsForPolicy organizations:DescribePolicy organizations:ListAWSServiceAccessForOrganization
"Organizations" related permissions can be ommitted. However , all the above mentioned "IAM" related permissions are necessary.
Ensure the permissions are available to the user / role / any aws principal which will be used for collection of data for the collector script.
Collecting data from AWS
Ensure you have aws credentials configured. Refer this for help.
Once the crendential is setup.
Ensure the output format of the aws profile being used for data collection is set to json as Aaia expects the data collected to be in json format.
In case of a requirement where data has to be collected from another instance; copy "Aaia_aws_collector.sh" file to the remote instance , run it and copy the generated "offline_data" folder to the Aaia path in the instance where Aaia is setup and carry on with following steps. This will be helpful in cases of consulting or client audit.
Loading the collected data to Neo4j DB
python Aaia.py -n -a load_data
-n supports "all" as value which means load all data collected and present within offline_data folder.
Please ensure you do not have profile as "all" in the credentials file as it may conflict with the argument. :P
Now we are ready to use Aaia.
Audit IAM through a custom module
As of now , a sample module is given as a skeleton example. One can consider this as a reference for building custom modules.
python Aaia.py -n all -m iam_sample_audit
Aaia is influenced and inspired from various amazing open source projects. Huge Shoutout to:
Aaia in Action
A sample visual of a dummy AWS Account's IAM:
A sample visual of a result of a cypher query to find all relations of a user in AWS IAM:
- Write a detailed documentation for understanding Aaia's Neo4j DB Schema
- Write a detailed documentation for developing custom modules for Aaia
- Write custom modules to evaluate 28 AWS privelege escalation methods identified by RhinoSecurity.
- Provide a cheatsheet of queries for identifying simple issues in AWS IAM
- Extend Aaia to other cloud providers.
