Visualizing AWS Attack Paths: How To Map IAM Privilege Escalation & Lateral Movement Like A Pro + Video

Introduction:

Understanding complex AWS resource relationships is critical for identifying hidden attack paths. Attackers often exploit misconfigured IAM roles, overly permissive security groups, and cross-region resource links to move laterally. `aws-visualizer` is an open-source tool that ingests AWS resources across regions and renders an interactive Cytoscape.js graph, integrating with `pathfinding.cloud` to highlight IAM privilege-escalation chains—giving defenders a visual battlefield to harden their cloud posture.

Learning Objectives:

Learn how to install and configure `aws-visualizer` to map EC2, VPCs, subnets, security groups, IAM, and Lambda across multiple AWS regions.
Identify IAM privilege escalation paths using `pathfinding.cloud` integration and visualize lateral movement vectors.
Apply remediation steps with AWS CLI commands and policy hardening techniques to block discovered attack paths.

You Should Know:

1. Installing and Running aws-visualizer on Linux/Windows

What it does:

`aws-visualizer` pulls resource data from your AWS account via the CLI/SDK and builds an interactive HTML graph. Use it to discover unknown dependencies and overly broad trust relationships.

Step‑by‑step guide:

Linux (Ubuntu/Debian):

 Install dependencies
sudo apt update && sudo apt install -y git nodejs npm python3-pip

Clone the repository (assuming GitHub - adjust URL if known)
git clone https://github.com/example/aws-visualizer.git  Replace with actual repo if found
cd aws-visualizer

Install Python requirements
pip3 install -r requirements.txt

Configure AWS credentials (if not already set)
aws configure

Run the ingestor (example command based on typical tools)
python3 aws_visualizer.py --regions us-east-1,us-west-2 --services ec2,vpc,iam,lambda

Windows (PowerShell as Admin):

 Install Chocolatey (if needed) then Node.js and Python
Set-ExecutionPolicy Bypass -Scope Process -Force; [System.Net.ServicePointManager]::SecurityProtocol = [System.Net.ServicePointManager]::SecurityProtocol -bor 3072; iex ((New-Object System.Net.WebClient).DownloadString('https://community.chocolatey.org/install.ps1'))
choco install nodejs python git -y

Clone and run
git clone https://github.com/example/aws-visualizer.git
cd aws-visualizer
pip install -r requirements.txt
python aws_visualizer.py --regions eu-central-1 --services all

After execution, open the generated `output.html` in a browser. Use the Cytoscape.js interface to filter by region/service and trace relationships (e.g., which EC2 instances have security group rules that allow access from an IAM role).

2. Integrating pathfinding.cloud for IAM Privilege Escalation Analysis

What it does:

`pathfinding.cloud` is an IAM attack path engine. When fed your IAM policies, it computes privilege escalation chains (e.g., `iam:CreatePolicyVersion` + iam:AttachUserPolicy). `aws-visualizer` overlays these as red edges on the graph.

Step‑by‑step guide:

1. Export IAM policies from AWS:

aws iam list-policies --scope Local --query 'Policies[].[PolicyName,Arn]' --output text > policies.txt

2. For each policy, download the document:

aws iam get-policy-version --policy-arn <ARN> --version-id v1 --query 'PolicyVersion.Document' --output json >> iam_policies.json

Upload to `pathfinding.cloud` (requires API key – free tier available):

curl -X POST https://api.pathfinding.cloud/v1/analyze \
-H "Authorization: Bearer YOUR_API_KEY" \
-H "Content-Type: application/json" \
-d @iam_policies.json > attack_paths.json

4. `aws-visualizer` natively supports this output. Place `attack_paths.json` in the same directory and re-run the visualizer with `–pathfinding` flag:

python aws_visualizer.py --pathfinding attack_paths.json

The graph will now highlight “risky trust links” – for example, a Lambda function that can assume a role with admin privileges.

Manual IAM Privilege Escalation Discovery Using AWS CLI

What it does:

Before relying on tools, you can manually query for classic escalation vectors using raw AWS CLI commands – essential for understanding the underlying risks.

Commands to run (Linux/macOS/Windows with AWS CLI):

 Find roles that can be assumed by any AWS service (risky)
aws iam list-roles --query 'Roles[?AssumeRolePolicyDocument.Statement[?Principal.Service]].[RoleName,AssumeRolePolicyDocument]' --output table

Identify users with iam:CreatePolicyVersion (allows backdoor insertion)
aws iam list-user-policies --user-name <user> --query 'PolicyNames' --output text
 Then check attached managed policies for CreatePolicyVersion
aws iam list-attached-user-policies --user-name <user> --query 'AttachedPolicies[?PolicyName==<code>AdministratorAccess</code>]'

Detect overly permissive security groups (0.0.0.0/0)
aws ec2 describe-security-groups --filters Name=ip-permission.cidr,Values='0.0.0.0/0' --query 'SecurityGroups[].[GroupId,GroupName]' --output table

Step‑by‑step remediation:

If you find a role that allows `sts:AssumeRole` from "Service": "ec2.amazonaws.com", an attacker who compromises an EC2 instance can steal the role’s token. Mitigation: Restrict to specific instances via `aws:SourceArn` condition.

4. Hardening Cross‑Region & VPC Peering Relationships

What it does:

Attackers often move laterally via VPC peering connections or Transit Gateways. `aws-visualizer` maps these relationships, but you must manually audit and restrict them.

Step‑by‑step guide to identify and lock down peering:

 List all VPC peering connections across regions
aws ec2 describe-vpc-peering-connections --query 'VpcPeeringConnections[].[VpcPeeringConnectionId,Status.Code,AccepterVpcInfo.Region,RequesterVpcInfo.Region]' --output table

For each active peering, check route tables for unintended access
aws ec2 describe-route-tables --filters "Name=vpc-id,Values=<vpc-id>" --query 'RouteTables[].Routes[?DestinationCidrBlock!=<code>local</code>]' --output table

Hardening commands (Linux/Windows):

 Remove a route that permits access to a sensitive subnet
aws ec2 delete-route --route-table-id rtb-xxxx --destination-cidr-block 10.0.2.0/24

Add a condition to the peering connection acceptance to limit traffic (via NACLs)
aws ec2 create-network-acl-entry --network-acl-id acl-xxxx --rule-number 100 --protocol tcp --rule-action deny --cidr-block 10.0.0.0/8 --port-range From=22,To=22 --ingress

Automating Attack Path Monitoring with Lambda & CloudWatch

What it does:

Schedule `aws-visualizer` to run daily and alert on new IAM privilege‑escalation paths using SNS.

Step‑by‑step (Python + AWS SDK):

Create a Lambda function (Python 3.9) with the `aws-visualizer` code packaged as a layer.
Use execution role that allows iam:List, ec2:Describe, lambda:List.
Add this code to send new paths to SNS:
```
import boto3, json, subprocess</li>
</ol>

def lambda_handler(event, context):
subprocess.run(["python3", "aws_visualizer.py", "--output", "/tmp/graph.html"])
with open("/tmp/attack_paths.json") as f:
paths = json.load(f)
if len(paths.get("escalation_chains", [])) > 0:
sns = boto3.client("sns")
sns.publish(TopicArn="arn:aws:sns:us-east-1:123456789012:SecurityAlerts",
Message=json.dumps(paths["escalation_chains"]),
Subject="New IAM Attack Paths Detected")
return {"status": "ok"}
```
4. Set up CloudWatch Events rule to trigger every 6 hours.
1. Mitigating Pathfinding.cloud Identified Risks Using IAM Policy Conditions
What it does:

Once `pathfinding.cloud` shows an escalation path (e.g., user A can pass a role to EC2 that has admin), you apply a condition to block that specific misuse.

Step‑by‑step guide:

Suppose the tool finds: `User:Alice` -> `iam:PassRole` -> `Role:EKS-Admin` -> `eks:CreateCluster` (admin equivalent).

Remediation policy (attach to Alice’s role):
```
{
"Version": "2012-10-17",
"Statement": [
{
"Effect": "Deny",
"Action": "iam:PassRole",
"Resource": "arn:aws:iam:::role/EKS-Admin",
"Condition": {
"StringEquals": {
"iam:PassedToService": "ec2.amazonaws.com"
}
}
}
]
}
```
Apply via CLI:
```
aws iam put-user-policy --user-name Alice --policy-name BlockEKSAdminPass --policy-document file://block.json
```
1. Windows-Specific Visualisation: Running aws-visualizer with WSL & Browser
What it does:

Windows users can leverage WSL2 for Linux tools while viewing the interactive graph in Edge/Chrome.

Step‑by‑step:
```
 In PowerShell as Admin
wsl --install -d Ubuntu
wsl --set-default-version 2

Inside WSL, follow Linux installation steps from Section 1
 After generating output.html, copy it to Windows temp
cp /home/user/aws-visualizer/output.html /mnt/c/Temp/

Launch from Windows
start c:\Temp\output.html
```
Use Windows Defender Firewall to restrict outbound access from the WSL instance to AWS only (prevents data exfiltration if the tool is compromised).

What Undercode Say:
- Key Takeaway 1: `aws-visualizer` plus `pathfinding.cloud` turns abstract IAM policies into actionable attack graphs – but only if you also manually verify the relationships with AWS CLI commands.
- Key Takeaway 2: Lateral movement in AWS often starts with a single overprivileged role or a missing `aws:SourceArn` condition. Automating daily graph diffs is the only way to keep up with dynamic cloud environments.
Analysis: The tool’s lack of a clear author is concerning; always audit open-source cloud tools in an isolated account before production use. However, the core technique – visualizing cross‑service relationships – is gold for red and blue teams. Most breaches (e.g., Capital One) involved misconfigured IAM roles that could have been spotted with such a graph. Pair this with automated remediation (like the Lambda example) to close paths within minutes instead of weeks. Remember that `pathfinding.cloud` itself is a third‑party API; for sensitive accounts, replicate its logic using open‑source IAM evaluation engines like `policy_sentry` or Parliament.

Prediction:

Within 18 months, major cloud providers will embed attack path visualisation natively into their security hubs (e.g., AWS IAM Access Analyzer will gain predictive graph features). Startups like `pathfinding.cloud` will be acquired, and “continuous monitoring of privilege escalation vectors” will become a compliance checkbox for SOC2 and ISO 27001. The demand for engineers who can interpret these graphs and write conditional IAM policies will skyrocket – manual CLI auditing will become a legacy skill, replaced by automated graph traversal attacks and defences.
