Cloud Security Penetration Testing

Misconfigurations Don't Show Up on Compliance Checklists. Attackers Find Them Anyway.

Cloud environments introduce an entirely different class of security risk — one that compliance frameworks were not designed to catch and that on-premises security expertise does not transfer to directly. Misconfigured IAM roles, exposed storage buckets, leaked credentials in CI/CD pipelines, overpermissioned service accounts, and lateral movement paths through cloud-native services are the conditions real-world attackers consistently exploit.

Evaluris assesses your cloud posture from an attacker's perspective across AWS and Azure — identifying every exploitable misconfiguration chain, privilege escalation path, and cross-account compromise scenario that represents real business risk.

Context

The Cloud Security Gap

Most organizations believe their cloud environment is secure because they passed a compliance audit or because their cloud provider marks the shared responsibility model as addressed. Neither of those things means your configuration is secure.

The shared responsibility model means the cloud provider secures the infrastructure. You are responsible for everything you configure on top of it — and the default configurations of most cloud services are permissive, not restrictive. Organizations that migrated to the cloud quickly, organizations that have grown their cloud footprint organically, and organizations where developers have direct cloud access almost always have exploitable misconfigurations that were never intentionally introduced and have never been tested.

The most common initial attack vector in cloud breaches is not a zero-day exploit. It is a misconfigured permission, an exposed API key, or a forgotten public storage bucket.

Approach

Methodology

1

Cloud Asset Discovery & Enumeration

Full inventory of cloud assets across the engagement scope: compute instances, storage buckets, databases, serverless functions, container registries, API gateways, IAM users, roles, and policies. Identification of internet-exposed resources and public access configurations.

2

IAM & Permission Analysis

Policy document analysis for overpermissioned roles, privilege escalation paths via IAM, assume-role chain analysis, cross-account access configurations, service control policy gaps, and permission boundary weaknesses.

3

Storage & Data Exposure Testing

S3 bucket (AWS) and Blob storage (Azure) public access testing, pre-signed URL abuse, bucket policy misconfiguration, and lifecycle policy analysis for sensitive data exposure.

4

Credential & Secrets Discovery

CI/CD pipeline secret scanning, environment variable exposure in serverless functions, EC2 instance metadata service (IMDSv1) abuse, hardcoded credentials in container images, and exposed API keys in source repositories.

5

Lateral Movement & Privilege Escalation

IAM privilege escalation chains, EC2 role abuse, Lambda function abuse, container escape paths, cross-service lateral movement, and persistence mechanism identification.

6

Network & Perimeter Configuration

Security group misconfiguration, public subnet exposure, VPC peering trust abuse, load balancer rule analysis, and WAF bypass testing.
