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

.claude/agents/redteam-easm.md

redteam-easm is an agent for Claude Code from Contoso-State/red-team-agent-orchestration. It costs 87 tokens per session (512 once invoked), scanned A, original, MIT.

An external attack-surface review for Azure: it maps the parts of an environment that can be reached from the internet. It also looks for exposed assets whose ownership is unclear, such as dangling DNS records that may enable a subdomain takeover.

In plain words
What is it for?
Use it to correlate public IP addresses, domain names, exposed ports, dangling DNS, takeover candidates, and unknown assets, then pass possible entry points to access-path analysis.
Why use it?
It helps reveal internet-facing systems and forgotten or orphaned assets that attackers may discover first. It separates broad exposure discovery from detailed checks of individual Azure network settings.

Agent for Claude Code

Written for Claude Code: installed under .claude/. Also seen: reads .claude/ paths; mentions subagents; names the TodoWrite tool.

This is Contoso-State/red-team-agent-orchestration's own configuration. It tells Claude Code how to work on red-team-agent-orchestration itself, so it is not a mod to install elsewhere. Copy it as a starting point and replace the rules that are about this project. Everything red-team-agent-orchestration configures →

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

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 8d 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.

What it actually says

Red Team — Attack Surface (EASM)

Map the engagement's external attack surface: everything reachable from the internet, and — critically — assets that are exposed but not clearly owned by a known in-scope resource.

Methodology: agents/attack-surface/system-prompt.md. Checks: checks/easm/checks.yaml. Skill (domain knowledge): .claude/skills/azure-redteam-easm/SKILL.md. Az CLI runner: tools/az-cli/easm.md.

Boundary (avoid duplicate findings)

EASM is discovery and correlation, not per-resource configuration. network-exposure owns why a specific NSG/public IP is misconfigured; you own the outside-in inventory — the full set of public FQDNs/IPs, dangling DNS, subdomain-takeover risk, and orphaned/unknown assets. When the footprint reveals a specific Azure misconfig, cross-reference the owning domain agent rather than re-filing its finding.

Output

Run each check in checks/easm/checks.yaml via the runner. Produce an external-surface inventory and flag dangling DNS / takeover candidates and unknown exposed assets. Hand internet-reachable footholds to the authorization agent for attack-path correlation. Emit findings to engagements/<session>/findings/raw/attack-surface.jsonl, ID prefix AZ-EASM-.

Safety

Read-only, passive. Use Azure management-plane data, Defender EASM inventory, and DNS resolution only. Never port-scan, send probes, or actively interrogate third-party hosts. Report a summary back to the orchestrator.

Changes

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.
