## Thirty seconds, no AWS account needed

```bash
pip install cloud-audit

cloud-audit agent-blast --demo          # a hijacked Bedrock Agent, two threat models, one screen
cloud-audit demo --save demo.json       # a full sample scan, then explore it offline:
cloud-audit blast-radius --report demo.json --resource arn:aws:iam::123456789012:role/support-bot-ticket-role
cloud-audit simulate     --report demo.json --fix aws-iam-018
cloud-audit exposure     --report demo.json
```

The sample account is invented. Everything derived from it (attack chains, root causes, breach cost,
security graph, agent reach) is produced by the same engines a real scan uses.

With credentials, the real thing is one command and read-only. The AWS-managed `SecurityAudit`
policy covers every check ([permissions](#aws-permissions)):

```bash
cloud-audit scan                         # default profile and region
cloud-audit scan --verify                # plus IAM policy-simulator proof for escalation paths
cloud-audit agent-blast --verify         # then: what your agents can reach, simulator-confirmed
```

## agent-blast: what a hijacked AI agent can reach

An AI agent in AWS is a bundle of IAM identities: the role the agent runs as, the execution roles of
the Lambda functions behind its tools, the roles of its knowledge bases, gateways and sandboxes.
When the agent is hijacked, the attacker acts with *those* identities. `agent-blast` answers what
that means, per agent, under two threat models:

| Threat model | What the attacker has | What is in reach |
|---|---|---|
| **Identity takeover** | the credentials of a role the agent runs as (sandbox escape, metadata-service read, leaked session) | the full role: privilege-escalation methods, AssumeRole hops, data |
| **Behaviour takeover** | nothing but a prompt (indirect prompt injection through a document, a ticket, a web page) | what the agent's tools can do, bounded by the tools' own execution roles |

Real output for the sample agent (`cloud-audit agent-blast --demo -a support-bot`):

└── Simulated, not executed: identity policies, the attached permissions boundary and SCPs are

    code does with its inputs is narrower.
```

The story the output tells: the support bot itself is harmless, but a document that tricks it into
calling `create-ticket` runs code under a role that can pass an admin role to a new Lambda. The
`search-docs` tool, meant to read product docs, can also read the production database secret and
write into the backups bucket. Every line names the identity, the action and the resource, so the
fix is a policy statement, not a debate.

The same engine covers AgentCore. For the sample gateway (`--demo -a tools-gw`) the headline is a
cross-agent one:

```
tools-gw (agentcore_gateway, eu-central-1)
├── tool: crm-sync can write into agent 'support-bot' knowledge base (RAG poisoning): arn:aws:s3:::kb-product-docs/*
├── inbound authorizer: NONE; policy engine: none
...
│   ├── tool: crm-sync s3:PutObject on arn:aws:s3:::kb-product-docs/* unverified write into agent
│   │   'support-bot' knowledge base (RAG poisoning)
...
├── Coverage notes
│   └── tool 'erp-mcp' (gateway_target_mcp_server): backend identity unknown, not assessed - remote
│       MCP server; credential provider: OAUTH
```

What `agent-blast` reads (all list/get, no charge):

- **Bedrock Agents**: the agent resource role, every action group at the `DRAFT` version resolved to
  its Lambda and the Lambda's execution role, knowledge bases resolved to their S3 data-source buckets.
- **AgentCore**: runtime role and network mode, gateway role with authorizer, policy engine and every
  target (Lambda, remote MCP server, API Gateway, OpenAPI, Smithy) with its credential provider,
  code interpreter and browser execution roles.
- **IAM policies** of exactly those identities (inline, attached, group), kept raw: action, resource,
  effect, whether a `Condition` is present. Conditions are flagged, never guessed. The simulator
  decides.

Then, per identity: the 64 privilege-escalation methods, AssumeRole hops through the trust graph,
and every data, secret, lateral, code-execution and model-invocation grant matched against concrete
resources. A knowledge-base bucket is always a concrete target, even behind `s3:*` on `*`, and
write access to it is reported as RAG poisoning. Anything the scanner could not read (a denied
region, a tool without an IAM identity) is a **coverage note**, never a silent pass.

`--verify` asks `iam:SimulatePrincipalPolicy` about every concrete pair, with the context an attacker
really has (no MFA on the session, TLS transport), and marks each reach `PROVEN`, `DENIED` (with the
policy layer that denied: SCP, permissions boundary) or `not asserted`. Output formats: `tree`,
`json`, `markdown`. The MCP server exposes the same report as `get_agent_blast`.

## A full scan

`cloud-audit scan` runs 110 read-only checks across 25 AWS services, correlates the findings into
attack chains, ranks the fixes by how many chains they break and prices the exposure. This is the

| Compliance | **6 frameworks** with per-control evidence: CIS AWS v3.0, SOC 2 Type II, ISO 27001:2022, HIPAA, NIS2, BSI C5:2020 | `scan --compliance`, `list-frameworks` |
| Drift and trend | diff two scans with exit codes; posture history with sparklines | `diff`, `trend` |
| Coverage gaps | a read the scanner was denied is reported as "not assessed", never as a pass | every command |
| Outputs | console, JSON, HTML report, SARIF (GitHub Code Scanning), Markdown | `scan --format` |
| MCP server | 7 read-only tools for Claude Code, Cursor and any MCP client, including `get_agent_blast` | `cloud-audit-mcp` |

The ten threat-feed detectors, as `cloud-audit threat-feed --list` prints them (rules pack `2026-Q2`):

| Pattern | Severity | What it catches |
|---|---|---|
| TF-001 | MEDIUM | SES recently verified identity (phishing setup precursor) |
| TF-002 | HIGH | Public Lambda Function URL (`AuthType=NONE`) |
| TF-003 | CRITICAL | AWS-attached credential quarantine policy |
| TF-004 | CRITICAL | Leaked-credentials scanner user-agent observed in CloudTrail |
| TF-005 | HIGH | Recently-created IAM role with cryptomining-style compute access |
| TF-006 | HIGH | EC2 or AgentCore using IMDSv1 / MMDSv1 (SSRF credential theft vector) |
| TF-007 | MEDIUM | CI/CD role at risk of whoAMI confusion attack |
| TF-008 | HIGH | CloudTrail tampering precursor (logging stopped or delivery failing) |
| TF-009 | HIGH | IAM Roles Anywhere trust anchor with external CA |
| TF-010 | HIGH | `AmazonDataZoneFullAccess` attached to a non-admin principal |

## Proof Mode: simulated, not guessed

Static analysis of IAM policies over-reports. Proof Mode asks AWS's own authorization engine,
`iam:SimulatePrincipalPolicy`, which is read-only and carries no per-call charge.

- `scan --verify` checks every detected escalation path. `verified: true` means the simulator allowed
  every required action; `false` means it denied one (the path is very likely a false positive);
  `null` means not asserted, with the reason in `verification_detail`.
- `agent-blast --verify` checks every concrete (principal, action, resource) reach, supplies the
  context an attacker with stolen or assumed credentials has, and names the layer that denied.

What the simulator evaluates as of 2026-07-30: identity policies, the attached permissions boundary,
the organization's SCPs including their condition keys, and the context keys you supply. What it does
not: resource control policies, VPC endpoint policies, role chaining, and resource-based policies for
IAM roles. cloud-audit says so on every verified line. A `true` proves the permission exists. It does
not prove an end-to-end attack; nothing is executed.

## Reports

```bash
cloud-audit scan --format html     -o report.html     # client-ready
cloud-audit scan --format sarif    -o results.sarif   # GitHub Code Scanning
cloud-audit scan --format json     -o report.json     # machine-readable, feeds every offline command
cloud-audit scan --format markdown -o report.md       # PR comments
cloud-audit scan --compliance cis_aws_v3 --format html -o cis.html
cloud-audit agent-blast --format markdown -o agents.md
```

## CI/CD

```yaml
- run: pip install cloud-audit
- run: cloud-audit scan --format sarif --output results.sarif
- uses: github/codeql-action/upload-sarif@v3
  with:
    sarif_file: results.sarif
```

`--quiet` exits with a code only: `0` clean, `1` findings, `2` error. Gate on severity with
`--min-severity high`. `cloud-audit diff old.json new.json --quiet` exits `1` on new findings, so a
daily scan catches ClickOps drift. The repository is also a composite GitHub Action
(`gebalamariusz/cloud-audit@v0`). Ready-made workflows: [basic scan](https://github.com/gebalamariusz/cloud-audit/blob/HEAD/examples/github-actions.yml),
[daily diff](https://github.com/gebalamariusz/cloud-audit/blob/HEAD/examples/daily-scan-with-diff.yml), [post-deploy](https://github.com/gebalamariusz/cloud-audit/blob/HEAD/examples/post-deploy-scan.yml).

## Installation

```bash
pip install cloud-audit                               # pip (recommended)
pipx install cloud-audit                              # isolated
uvx --from cloud-audit cloud-audit scan               # no install
docker run ghcr.io/gebalamariusz/cloud-audit scan     # Docker (also on Docker Hub: haitmg/cloud-audit)
```

Docker with credentials:

```bash
docker run -v ~/.aws:/home/cloudaudit/.aws:ro ghcr.io/gebalamariusz/cloud-audit scan
```

Python 3.10 to 3.13. Dependencies: boto3, typer, rich, pydantic, jinja2, pyyaml, mcp.

## AWS permissions

Read-only. Attach the AWS-managed `SecurityAudit` policy; it covers every check, the IAM escalation
analysis, the agent inventory and Proof Mode:

```bash
aws iam attach-role-policy --role-name auditor \
  --policy-arn arn:aws:iam::aws:policy/SecurityAudit
```

cloud-audit never modifies your infrastructure. `simulate`, `blast-radius`, `exposure`, `diff`,
`trend` and `agent-blast` run locally against a saved scan and make no AWS calls; `--verify` adds
simulator calls only. Regions where a service does not exist are skipped; regions where the scanner
is denied a read are listed as coverage gaps.

## MCP server

Seven read-only tools for AI assistants: `scan_aws`, `get_findings`, `get_attack_chains`,
`get_remediation`, `get_health_score`, `list_checks`, `get_agent_blast`.

```bash
claude mcp add cloud-audit -- uvx --from cloud-audit cloud-audit-mcp
```

Then ask: *"scan my AWS account and tell me what my Bedrock agents could reach if hijacked"*.

<details>
<summary>Common flags and configuration</summary>

```bash
cloud-audit scan -R                                      # show remediation inline
cloud-audit scan --profile prod --regions eu-central-1   # profile / region
cloud-audit scan --regions all                           # all enabled regions
cloud-audit scan --role-arn arn:aws:iam::...:role/audit  # cross-account
cloud-audit scan --export-fixes fixes.sh                 # every CLI fix as a script
cloud-audit scan --categories security,cost              # skip reliability/performance checks
cloud-audit agent-blast -a support-bot --profile prod --verify
```

Defaults live in `.cloud-audit.yml` (regions, `min_severity`, `exclude_checks`, time-boxed
`suppressions`). Environment variables (`CLOUD_AUDIT_REGIONS`, `CLOUD_AUDIT_MIN_SEVERITY`, ...)
override the file; CLI flags override everything. See the
[configuration guide](https://haitmg.pl/cloud-audit/configuration/config-file/).
