red-team-agent-orchestration: Skill for Claude Code

.agents/skills/azure-redteam-easm/SKILL.md

azure-redteam-easm is a skill for Claude Code, Codex from Contoso-State/red-team-agent-orchestration. It costs 117 tokens per session (770 once invoked), scanned A, original, MIT.

An External Attack Surface Management skill for Azure, meaning a review of what an organization exposes to the internet. It discovers public addresses and names, exposed ports, forgotten resources, and DNS records that may point to missing services.

In plain words
What is it for?
Use it to inventory public IPs and hostnames, identify exposed management or database ports, find dangling DNS records and subdomain-takeover risks, and flag orphaned assets.
Why use it?
It provides an outside-in view that can reveal assets missed by an internal inventory, including abandoned or potentially hijackable domains. It is designed for passive discovery and correlation.

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 A, and why

azure-redteam-easm 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 11d 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.

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.

Azure Red Team — Attack Surface (EASM)

You take the outside-in view: what does this organization expose to the internet, and which of those assets are unowned, forgotten, or hijackable? EASM is discovery and correlation — you build the external footprint inventory and surface the dangerous unknowns, then hand specifics to the domain agents that own them.

Full methodology: agents/attack-surface/system-prompt.md. Checks: checks/easm/checks.yaml. Az CLI runner: tools/az-cli/easm.md — the read-only, passive commands you execute.

What You Hunt

  • Public footprint inventory: every public IP and resolvable FQDN tied to in-scope resources (App Service, Front Door, public IPs, storage/AI endpoints, AKS ingress, APIM).
  • Dangling DNS / subdomain takeover: DNS records (CNAME/A) pointing at deprovisioned Azure resources (*.azurewebsites.net, *.blob.core.windows.net, *.trafficmanager.net, *.cloudapp.azure.com, Front Door endpoints) that no longer exist — hijackable.
  • Exposed management/data ports: internet-reachable management surfaces (RDP/SSH/WinRM, database ports, Kubernetes API) inferred from NSG/public-IP correlation.
  • Orphaned / unknown assets: public endpoints that resolve into the tenant but map to no known in-scope resource — shadow IT or stale infrastructure.
  • Defender EASM signal: when a Microsoft Defender EASM workspace exists, ingest its discovered inventory and high-priority observations.

How You Work

  1. Build the external footprint from inventory: enumerate public IPs (Microsoft.Network/publicIPAddresses), and the public hostnames of App Service, Front Door/CDN, storage, AI, AKS ingress, APIM.
  2. Resolve DNS zones (Microsoft.Network/dnsZones) records and flag CNAME/A targets that no longer resolve to a live owned resource (takeover risk).
  3. If a Defender EASM resource exists, pull its inventory/observations via az rest (GET).
  4. Correlate each exposed asset to an owner; flag assets with no owner as unknown.
  5. Cross-reference specific misconfigs to the owning agent (network/web/compute/data) instead of duplicating.
  6. Emit findings to engagements/<session>/findings/raw/attack-surface.jsonl, ID prefix AZ-EASM-.

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.
