hunt-ics

hunt-ics is a skill for Claude Code, Codex from Encod3d-Sec/TORCH. It costs 94 tokens per session (2,060 once invoked), scanned A, original, MIT.

A guide for testing industrial control systems, such as PLCs, HMIs, and SCADA networks. These systems operate machinery and processes using protocols including Modbus, S7comm, EtherNet/IP, and DNP3.

In plain words
What is it for?
Use it to identify industrial services, inspect PLCs and HMIs, test coils and registers in permitted simulations, and work with OpenPLC or Node-RED SCADA targets.
Why use it?
It provides a safety boundary for testing systems that can control real equipment, including a strict read-only approach unless the target is an explicitly authorized lab or simulation.

These are SkillSpector’s own severities. On a checked sample its high-severity flags on skills were ~96% false positives — a documented command, a public API, a “never do X” rule — so we show them as a caution to read, not a verdict. Why →

    This content may contain harmful instructions that could cause physical harm if followed. CRITICAL: Review carefully before use.

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

hunt-ics 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.

How it starts

The opening of the file, as written. The whole thing — 79 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Hunt: ICS / SCADA / OT

Assumes hunt-core for the scope gate, two-account rule, confirmation gate, enumeration limits, stop conditions, wiki protocol, FIND output, and Deadends. Do not re-derive any of that here.

SAFETY - hard stop, overrides everything below

Writing to a live PLC moves real machinery: it can over-pressure a vessel, over-speed a motor, or disable a safety interlock, and so damage equipment or injure and kill people. Only ever drive a process toward a dangerous state on a target that is EXPLICITLY an authorized lab or CTF simulation. Never on a real plant, and never when scope carries no_dos/passive_only - there OT is READ-ONLY (FC1-4), never write (FC5/6/15/16). The instant the objective is met (e.g. the flag the HMI/CCTV reveals is in hand), STOP writing and revert any coil/register you changed if you can. This is a hard stop and it outranks every other note in this file.

Wiki

qmd_query "ICS SCADA OT Modbus S7comm EtherNet/IP DNP3 OpenPLC Node-RED PLC HMI coil holding register" via wiki-search MCP

Hub: [[network-moc]] (live index). Primary page: [[ics-scada-modbus]]. Payload arsenal: wiki/payloads/modbus.md. Anchors: [[iot-attacks]], [[firmware-hardware]].

Attack surface (ranked by exploitation value)

  1. Modbus / TCP 502 - no auth, no session, trivially readable AND writable. The primary lever: FC1-4 read coils/registers, FC5/6/15/16 write them. Highest value, highest danger.
  2. OpenPLC web (8080) and Node-RED (1880, dashboard /ui) - the SCADA/IT side that drives the PLC. OpenPLC routes /programs /monitoring /hardware /users; authed OpenPLC = upload-program RCE. Node-RED /ui socket.io config NAMES the registers.
  3. HMI web app (Flask/Werkzeug with an /api/... live-state endpoint) - not itself the lever but the ORACLE that tells you whether a write landed.
  4. S7comm / TCP 102 (S7/iso-tsap) - python-snap7 db_read for creds/flags in data blocks.
  5. EtherNet/IP 44818, DNP3 20000, then BACnet 47808/udp, Fox 1911/4911, OPC-UA 4840 - enumerate with the matching nmap scripts; less commonly the CTF lever, but map them.

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.

hunt-ics is a skill published in the GitHub repository Encod3d-Sec/TORCH (314 stars, last pushed 6d ago), licensed MIT. It adds 94 tokens to every session and 2,060 once invoked, about $0.0005 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 2026-08-30.
