ドキュメント

OT / ICS Security

ACTION REQUIRED(读完后立刻执行)

  1. NOW: 读取 ../field-journal/precedent-pentest.md工控环境误操作可致物理危害
  2. NOW: 书面授权必须写清:站点、网段、是否允许主动扫描/写寄存器
  3. NOW: case-init;默认 passive-firstready_for_act 前禁止对 PLC 写操作
  4. NEXT: tool-index;多数工控工具需手动与隔离实验网
  5. ACT: 资产与分区识别 → 暴露面 → 只读验证

适用场景

  • 工控/SCADA/DCS 安全评估(授权)
  • Purdue 模型分区与跨区通道
  • Modbus/DNP3/S7/EtherNet/IP 等协议暴露
  • 工程师站、HMI、历史库、跳板主机
  • IT/OT 融合边界(防火墙规则、单向闸)

安全铁律(MUST)

MUST NOT 在未明确允许时:
- 对 PLC 写线圈/寄存器
- 全网高速率扫描生产 OT
- 中断安全仪表系统(SIS)相关路径
优先:只读识别、流量镜像、离线固件/配置分析

工作流

Phase 1 — 分区与资产

□ Purdue L0–L5 草图:现场设备 → 控制 → 监督 → 站点 DMZ → 企业
□ 资产清单:PLC/RTU/HMI/工程师站/历史库/Jump host
□ 协议与端口基线(仅授权网段)

Phase 2 — 被动与只读

□ SPAN/镜像 PCAP → protocol-reverse / Wireshark 工控解析器
□ 配置与工程文件离线审计(TIA/RSLogix 导出等)
□ 默认口令与明文协议(Modbus 无认证)记录为 Finding,不写盘改值

Phase 3 — 受限主动(仅授权)

□ 低速识别,维护窗口
□ 只读功能码优先
□ 每步 Evidence;异常立即停止并通报

Phase 4 — 固件/补丁面

□ 控制器固件版本 → CVE 映射(不盲刷固件)
□ 联合 firmware-pentest 做离线镜像分析

工具链

工具用途注意
Wireshark 工控 dissectors被动解析镜像流量
Nmap NSE(受限)识别速率与时间窗
Claroty/Nozomi 等资产发现商业/现场
PLC 厂商工程软件配置审计离线优先
binwalk / Ghidra固件离线

参考

  • references/ot-safe-assessment.md
  • ../firmware-pentest/ ../protocol-reverse/ ../network via pentest-tools

路由上下文

上游: MASTER R28
下游: 固件深挖 firmware-pentest;协议 protocol-reverse;IT 横向 windows-ad/attack-chain
同级: 不要用普通 Web 扫默认参数打 OT

任务完成自检

  • 是否默认被动/只读并记录授权边界?
  • 是否避免对控制回路写操作(除非明确允许)?
  • Finding 是否含物理/过程影响说明?
  • Checklist / journal?

Individual skills in this repo

This repo contains 20 individual skills — each has its own dedicated page.

api-security

Use for authorized security assessment of REST, GraphQL, WebSocket, or SOAP APIs, including discovery, authentication, authorization, rate-limit, and CI/CD testing.

apk-reverse

在 CLI 环境下做 Android APK 逆向时使用。适用于 APK 解包、Java 反编译、smali 修改、重打包、Frida 动态 Hook,以及按需切换到 so/native 分析。优先使用本机已安装的 jadx、apktool、frida、adb、ida-reverse、radare2。

attack-chain

Use for authorized multi-stage attack-path planning and orchestration when a task spans reconnaissance, initial access, privilege escalation, lateral movement, or impact assessment. Route single-stage tasks directly to their specialist skill.

binary-diff

|

binary-ninja-reverse

Use for authorized binary analysis in Binary Ninja, including HLIL/MLIL/LLIL inspection, strings/imports/exports, cross-references, types, patch review, Python API automation, and optional Binary Ninja MCP or localhost HTTP integration.

browser-automation

|

browser-extension-reverse

Use for authorized reverse engineering of browser extensions (Chrome/Firefox) including manifest analysis, background workers, and extension-based credential or traffic logic recovery.

case-review

Reviews a reverse-skill case package for scope readiness, Evidence to Finding to Path traceability, work item coverage, timeline references, and optional artifact hash integrity before report handoff.

cloud-k8s

Use for authorized cloud, container, and Kubernetes security assessment including metadata SSRF, IAM misconfig, container escape paths, and cluster RBAC review.

code-audit

Use for authorized source-code security review and SAST workflows including Semgrep, CodeQL patterns, dangerous API hunting, and fix verification.

ctf-sandbox

Thin PRIMARY for CTF / AWD / 靶场 multi-type orchestration. Hands off to the sidecar CTF-Sandbox-Orchestrator. Use when the user says CTF, AWD, 靶场, or 比赛题 and no more specific pwn/APK/IDA route already won.

database-security

Use for authorized database security assessment covering PostgreSQL/MySQL/MSSQL/Mongo/Redis exposure, authz, UDF/command paths, and misconfiguration review.

diagram-generator

generate, refine, validate, and render diagrams from natural language, notes, code snippets, schemas, tables, or existing diagram source. use for flowcharts, swimlanes, sequence diagrams, state diagrams, er diagrams, class diagrams, architecture/c4-style diagrams, dependency graphs, gantt charts, mind maps, user journeys, sankey-style flows, org charts, network graphs, and other visual models. supports mermaid by default, graphviz dot for complex graph layout, plantuml for uml-heavy engineering diagrams, and svg output when direct markup is more reliable.

digital-forensics

Use for authorized digital forensics including memory dumps, disk timelines, PCAP investigation, artifact triage, and IR evidence preservation.

docs-generator

|

dotnet-reverse

.NET / C# 二进制逆向。当目标是 .NET assembly(PE 头含 CLR、.exe/.dll 托管程序)、C# 编译产物(含 NativeAOT)、红队 Sharp* 工具(Rubeus / SharpHound / SharpHound 等)、.NET 混淆程序(ConfuserEx / SmartAssembly / Babel / Eazfuscator)、.NET loader / info-stealer / 套壳 malware 时使用。优先用 dnSpyEx + de4dot,需要 AI 直接操作时联动 dnSpy MCP。不用于纯 native 二进制(走 reverse-engineering / ida-reverse)。
