CloudFox makes read/describe API calls against the cloud account whose credentials you supply. Run it ONLY against accounts you own or are authorized to test under a signed scope. Although CloudFox is read-only by design, the enumeration it performs is reconnaissance against a live environment and must be in scope.\n\n## Overview\n\nCloudFox is an open-source command-line tool from Bishop Fox that helps penetration testers and red teamers gain *situational awareness* in unfamiliar cloud environments. Where tools like ScoutSuite focus on a defender-style configuration audit, CloudFox is built from the attacker's perspective: it answers questions like \"what are the most attackable secrets, endpoints, and instances in this account, and what can the identity I just compromised actually reach?\" It is read-only — it only performs `Describe`/`List`/`Get` style calls — and writes its findings to per-command CSV/TXT/loot files plus a combined report directory, so output can be triaged offline.\n\nCloudFox covers AWS most deeply (30+ commands) and supports Azure. The workhorse is `cloudfox aws all-checks`, which runs the full battery of enumeration commands with sensible defaults: inventory, internet-reachable `endpoints`, EC2 `instances` (with IPs and instance-profile roles), `iam-simulator` and `permissions` for IAM analysis, `principals`, `secrets` from Secrets Manager/SSM, `buckets`, `role-trusts` (which identities can assume which roles — a core attack-path primitive), `access-keys`, `route53`, `ecr`, `lambda`, and more. CloudFox also emits ready-to-run command suggestions (e.g. `aws s3 ls` lines, `aws ssm start-session` lines) in its \"loot\" files so an operator can pivot immediately.\n\nThis skill covers installing CloudFox, authenticating to AWS and Azure, running targeted and full enumeration, interpreting the high-value outputs (role-trusts, secrets, endpoints), and feeding the results into attack-path planning.

Confirm the identity and run all AWS checks\n```bash\naws sts get-caller-identity --profile assess\ncloudfox aws --profile assess all-checks -o ./loot\n```\n\n### 2. Inventory the account footprint\n```bash\ncloudfox aws --profile assess inventory\n```\n\n### 3. Find internet-reachable endpoints and exposed instances\n```bash\ncloudfox aws --profile assess endpoints\ncloudfox aws --profile assess instances\n```\n\n### 4. Enumerate IAM principals, permissions, and role-trust attack paths\n`role-trusts` is the key lateral-movement primitive — it shows who can assume what.\n```bash\ncloudfox aws --profile assess principals\ncloudfox aws --profile assess permissions\ncloudfox aws --profile assess role-trusts\ncloudfox aws --profile assess access-keys\n```\n\n### 5. Hunt for exposed secrets\n```bash\ncloudfox aws --profile assess secrets\n```\n\n### 6. Enumerate storage, registries, and serverless\n```bash\ncloudfox aws --profile assess buckets\ncloudfox aws --profile assess ecr\ncloudfox aws --profile assess lambda\ncloudfox aws --profile assess route53\n```\n\n### 7. Use IAM simulator to confirm what a principal can do\n```bash\ncloudfox aws --profile assess iam-simulator\n```\n\n### 8. Enumerate Azure\nCloudFox Azure works against the subscriptions the `az` session can see.\n```bash\ncloudfox azure inventory --outdir ./azure-loot\ncloudfox azure rbac\ncloudfox azure storage\ncloudfox azure vms\n```\n\n### 9. Triage the loot\nCloudFox writes per-command CSV/TXT plus a `loot` directory of pivot commands.\n```bash\nls -R ./loot/cloudfox-output/\n# Loot files contain ready-to-run follow-ups, e.g. aws s3 ls / ssm start-session lines\n```\nSee `scripts/agent.py` to run a curated set of commands and summarize output files.\n\n## Tools and Resources\n\n| Resource | Purpose | Link |\n|----------|---------|------|\n| CloudFox GitHub | Source, releases, full command list | https://github.com/BishopFox/cloudfox |\n| CloudFox docs/wiki | Per-command output explanations | https://github.com/BishopFox/cloudfox/wiki |\n| Bishop Fox CloudFox blog | Design and usage walkthrough | https://bishopfox.com/blog/introducing-cloudfox |\n| AWS CLI reference | Follow-up exploitation commands | https://docs.aws.amazon.com/cli/latest/reference/ |\n| Pacu | Active exploitation after enumeration | https://github.com/RhinoSecurityLabs/pacu |\n\n## OPSEC and Detection Considerations\n\nCloudFox is read-only, but its enumeration is far from silent. Each command issues\nmany `Describe*`/`List*`/`Get*` API calls in a short burst, which is highly visible\nto defenders:\n\n- **CloudTrail** records every read call. A spike of `iam:ListUsers`, `iam:ListRoles`,\n  `secretsmanager:ListSecrets`, `ec2:DescribeInstances`, and `sts:GetCallerIdentity`\n  from one principal within seconds is a strong enumeration signal.\n- **GuardDuty** finding types such as `Discovery:IAMUser/AnomalousBehavior` and\n  `Discovery:S3/MaliciousIPCaller` can fire on this burst pattern.\n- Defenders should baseline normal API-call rates per principal and alert on\n  enumeration bursts, especially from new IPs/ASNs or newly created credentials.\n\nFor an authorized assessment, document the source IP and timestamp of CloudFox runs\nso the blue team can correlate, and prefer running from an in-scope, attributable host.\n\n## Recommended Operator Workflow\n\n1. Run `all-checks` once to populate the full output directory.\n2. Open `role-trusts` first — it reveals the assume-role graph for lateral movement.\n3. Cross-reference `secrets` and `env-vars` for credentials that unlock new principals.\n4. Use `endpoints` + `instances` to map externally reachable attack surface.\n5. Feed confirmed assume-role / privesc candidates into Pacu for active exploitation.\n\n## High-Value Command Reference\n\n| Command | Why it matters |\n|---------|----------------|\n| `all-checks` |
