attack-path-analysis

An AWS security analysis that connects weaknesses and exposed resources into plausible attack paths, mapped to MITRE ATT&CK. AWS is Amazon’s cloud platform, and MITRE ATT&CK is a public framework describing how attackers operate.

In plain words
What is it for?
Use it to examine internet-reachable systems, risky permissions, network access, and exposed data as possible compromise paths.
Why use it?
It shows how separate findings could combine into a route from an exposed entry point to a serious impact, instead of leaving them as an unordered list.

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 A, and why

attack-path-analysis scanned grade A with 0 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 yesterday.

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.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

The opening of the file, as written. The whole thing — 103 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Attack path analysis (MITRE ATT&CK)

Explain how an adversary could realistically compromise a scanned AWS account, as chained attack paths mapped to MITRE ATT&CK tactics and techniques — not an unordered list of findings.

The value is the chain: an internet-reachable instance is only the entry point; the risk is what it leads to (a permissive role, an unencrypted database, a public bucket). Build paths from entry to impact.

Tools

Gather the raw material, then correlate it:

  • analyze_service_exposure — the internet-reachable surface (EC2, Lambda, databases, entry points) with evidence chains. The entry points.
  • get_security_assessment_data — the full findings set across identity, network, data, logging, service exposure. The weaknesses to chain.
  • analyze_iam_permissions — over-privileged users/roles, admin/wildcard grants, missing MFA, stale keys. Returns {summary, findings}. The escalation and lateral-movement fuel.
  • find_public_ec2_instances, find_publicly_accessible_databases, find_public_s3_buckets — specific exposed resources for concrete paths.
  • find_security_group_violations — the network reachability that connects steps.
  • get_iam_users — MFA and credential state for initial-access realism.

Workflow

1. Resolve the scan

Latest scan unless the user names one (list_scans accepts account_number). State the account and scan date.

2. Enumerate the ingredients by tactic

Load references/attack-technique-map.md. Sort the findings into ATT&CK tactics using it:

  • Initial Access — internet-reachable instances/functions/databases, public entry points, users without MFA.
  • Privilege Escalation / Credential Access — instance roles and users with broad or wildcard IAM, stale access keys, root weaknesses, unsecured credentials.
  • Lateral Movement — permissive internal security groups, network connectivity, shared roles.
  • Collection / Exfiltration / Impact — public or unencrypted data stores, public buckets, missing logging that would hide the activity.

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.

attack-path-analysis is a skill published in the GitHub repository Cognisn/cloudledger (0 stars, last pushed 13d ago), licensed MIT. It adds 88 tokens to every session and 1,192 once invoked, about $0.0004 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-31.
