Cloud-Native Security

Cloud-Native Security is a skill for Claude Code from allsmog/vuln-scout. It costs 93 tokens per session (4,926 once invoked), scanned B, original, MIT.

A guide to security risks in cloud-hosted applications and infrastructure, including AWS, GCP, Azure, Kubernetes, serverless functions, and infrastructure configuration files.

In plain words
What is it for?
Use it to review cloud APIs, Kubernetes and Helm files, serverless deployments, Terraform or CloudFormation, cloud credentials, and SSRF paths to metadata services.
Why use it?
Cloud systems introduce risks such as exposed instance metadata, overly broad permissions, unsafe containers, and misconfigured storage or services. This guide helps identify those environment-specific problems.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade B, and why

Cloud-Native Security scanned grade B with 2 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 7d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Downgraded: this mod is about security review, or the phrase is quoted, so it is likely naming the pattern rather than instructing it.

Cloud-Native Security Patterns Reference

Purpose

Identify security vulnerabilities specific to cloud-native environments, including IMDS exploitation, cloud provider misconfigurations, Kubernetes security issues, and serverless attack vectors. Cloud-native applications have unique trust boundaries and implicit assumptions that create vulnerability classes not present in traditional deployments.

When to Use

Activate this skill when:

  • Reviewing code that interacts with AWS, GCP, or Azure APIs
  • Auditing Kubernetes manifests and Helm charts
  • Assessing serverless functions (Lambda, Cloud Functions, Azure Functions)
  • Evaluating SSRF findings for cloud metadata exploitation
  • Reviewing Infrastructure as Code (Terraform, CloudFormation, Pulumi)
  • Checking for hardcoded cloud credentials

Instance Metadata Service (IMDS)

Overview

Cloud instances expose a metadata service at a well-known IP address. SSRF vulnerabilities in cloud-hosted applications can be exploited to access this metadata, potentially leaking IAM credentials, instance identity tokens, and configuration data.

IMDS Endpoints

Provider IPv4 Endpoint IPv6 Endpoint Protocol
AWS EC2 169.254.169.254 fd00:ec2::254 HTTP
GCP metadata.google.internal (169.254.169.254) N/A HTTP
Azure 169.254.169.254 N/A HTTP
DigitalOcean 169.254.169.254 N/A HTTP
Oracle Cloud 169.254.169.254 N/A HTTP

AWS IMDSv1 vs IMDSv2

Feature IMDSv1 IMDSv2
Request method Simple GET PUT to get token, then GET with token header
SSRF exploitable Yes (single GET request) Harder (requires PUT + custom header)
Mitigation Disable or upgrade Enforce IMDSv2-only via HttpTokens: required

IMDSv1 Exploitation (simple GET):

GET http://169.254.169.254/latest/meta-data/iam/security-credentials/<role-name>

IMDSv2 Exploitation (requires PUT + header):

PUT http://169.254.169.254/latest/api/token
X-aws-ec2-metadata-token-ttl-seconds: 21600

GET http://169.254.169.254/latest/meta-data/iam/security-credentials/<role-name>
X-aws-ec2-metadata-token: <token>

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.

Cloud-Native Security is a skill published in the GitHub repository allsmog/vuln-scout (24 stars, last pushed 2mo ago), licensed MIT. It adds 93 tokens to every session and 4,926 once invoked, about $0.0005 per session on Opus 5. A static security scan graded it B with 2 findings (cloud metadata endpoint, makes network calls). No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
