Cloud Penetration Testing

Purpose

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.

unzip awscliv2.zip && sudo ./aws/install

# GCP CLI
curl https://sdk.cloud.google.com | bash
gcloud init

# Additional tools

Core Workflow

Phase 1: Reconnaissance

Gather initial information about target cloud presence:

# Azure: Get federation info
curl "https://login.microsoftonline.com/getuserrealm.srf?login=user@target.com&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

Issue	Solutions
Authentication failures	Verify credentials; check MFA; ensure correct tenant/project; try alternative auth methods
Permission denied	List current roles; try different resources; check resource policies; verify region
Metadata service blocked	Check IMDSv2 (AWS); verify instance role; check firewall for 169.254.169.254
Rate limiting	Add delays; spread across regions; use multiple credentials; focus on high-value targets
