yaklang/active-directory-certificate-services

AD証明書サービス攻撃プレイブック。ESC1～ESC13テンプレート悪用、NTLMリレーによる登録、CAオフィサー悪用、証明書ベースの永続化を介した権限昇格のために、誤構成のAD CSを標的とする際に使用します。

active-directory-certificate-services とは？

このスキルは、Active Directory証明書サービス（AD CS）における誤構成を悪用するための攻撃プレイブックです。主に、ESC1～ESC13に分類される証明書テンプレートの脆弱性、NTLMリレー攻撃による証明書登録、CAオフィサーアカウントの不正利用、証明書を用いた永続化手法をカバーしています。開発者やセキュリティエンジニアは、このスキルを使用して、AD CS環境のセキュリティテストや権限昇格のシナリオを実行できます。対応プラットフォームとしてYaklangが想定されており、実際の攻撃手順やコマンド例が含まれています。このスキルは、侵入テストやレッドチーム演習において、AD CSの脆弱性を体系的に検証するのに役立ちます。

AD証明書サービス攻撃プレイブック。ESC1～ESC13テンプレート悪用、NTLMリレーによる登録、CAオフィサー悪用、証明書ベースの永続化を介した権限昇格のために、誤構成のAD CSを標的とする際に使用します。

概要

このスキルは、Active Directory証明書サービス（AD CS）の誤構成を悪用するための攻撃プレイブックです。以下の主要な攻撃ベクトルをカバーします：

  • ESC1～ESC13: 証明書テンプレートの権限昇格脆弱性
  • NTLMリレー: NTLM認証を中継して証明書登録を強制
  • CAオフィサー悪用: CAオフィサーアカウントの権限を悪用
  • 証明書ベースの永続化: 証明書を使用した持続的なアクセス

使用方法

Yaklang環境で以下のコマンドを実行してスキルを呼び出します：

yak run yaklang/active-directory-certificate-services

必要条件

  • ターゲットAD CS環境へのネットワークアクセス
  • 適切な認証情報（ドメインユーザーアカウントなど）
  • Yaklangのインストール

関連スキル

  • yaklang/kerberos-attacks
  • yaklang/ntlm-relay

Individual skills in this repo

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

yaklang/401-403-bypass-techniques

401/403 bypass playbook. Use when encountering access-denied responses on admin panels, API endpoints, or restricted paths. Covers path manipulation, HTTP method tampering, header injection, protocol downgrade, and automated bypass tools.

yaklang/active-directory-acl-abuse

Active Directory ACL abuse playbook. Use when exploiting misconfigured AD permissions including GenericAll, WriteDACL, DCSync rights, shadow credentials, LAPS reading, GPO abuse, and BloodHound-guided attack paths.

yaklang/active-directory-kerberos-attacks

Kerberos attack playbook for Active Directory. Use when targeting AD authentication via AS-REP roasting, Kerberoasting, golden/silver/diamond tickets, delegation abuse, or pass-the-ticket attacks.

yaklang/ai-ml-security

AI/ML security playbook. Use when assessing model supply chain attacks (pickle RCE, poisoned weights), adversarial examples, model poisoning, model stealing, data privacy attacks (membership inference, model inversion), and autonomous agent security risks.

yaklang/android-pentesting-tricks

Android pentesting playbook. Use when testing Android applications for SSL pinning bypass, exported component abuse, WebView vulnerabilities, intent redirection, root detection bypass, tapjacking, and backup extraction during authorized mobile security assessments.

yaklang/anti-debugging-techniques

Anti-debugging detection and bypass playbook. Use when reversing protected binaries that detect debuggers via ptrace, PEB flags, timing checks, or signal/exception handlers on Linux and Windows.

yaklang/api-auth-and-jwt-abuse

API authentication and JWT abuse playbook. Use when testing bearer tokens, API keys, claim trust, header spoofing, rate limits, and API auth boundary weaknesses.

yaklang/api-authorization-and-bola

API authorization and BOLA testing playbook. Use when APIs expose object identifiers, nested resources, hidden writable fields, or weak function-level authorization.

yaklang/api-recon-and-docs

API reconnaissance and documentation review playbook. Use when discovering endpoints, schemas, versions, OpenAPI specs, hidden docs, and surface area for API testing.

yaklang/api-sec

Entry P1 category router for API security. Use when choosing between API recon, authorization, token abuse, and hidden-parameter workflows before any deeper API topic skill.

yaklang/arbitrary-write-to-rce

Arbitrary write to RCE playbook. Use when you have an arbitrary write primitive (from heap exploitation, format string, or OOB write) and need to convert it into code execution by targeting GOT, hooks, _IO_FILE vtable, exit_funcs, TLS_dtor_list, modprobe_path, .fini_array, or C++ vtables.

yaklang/authbypass-authentication-flaws

Authentication bypass testing playbook. Use when assessing login flows, password reset logic, account recovery, MFA bypass, token predictability, brute-force resistance, and session boundary flaws.

yaklang/auth-sec

Entry P1 category router for authentication and authorization. Use when testing login flows, sessions, object authorization, JWT, OAuth, CORS, CSRF, and enterprise SSO weaknesses before any deeper auth topic skill.

yaklang/binary-protection-bypass

Binary protection bypass playbook. Use when identifying and bypassing ASLR, PIE, NX/DEP, stack canary, RELRO, FORTIFY_SOURCE, CET, and MTE protections in ELF binaries to enable exploitation.

yaklang/browser-exploitation-v8

Browser and V8 exploitation playbook. Use when exploiting JavaScript engine vulnerabilities including JIT type confusion, incorrect bounds elimination, and V8 sandbox bypass to achieve renderer RCE and sandbox escape in Chrome/Chromium.

yaklang/business-logic-vuln

Entry P1 category router for business logic testing. Use when workflow abuse, race conditions, pricing flaws, or multi-step state attacks matter more than parser-level input injection.

yaklang/business-logic-vulnerabilities

Business logic vulnerability playbook. Use when reasoning about workflows, race conditions, price manipulation, coupon abuse, state machines, and multi-step authorization gaps.

yaklang/classical-cipher-analysis

Classical cipher analysis playbook. Use when encountering substitution ciphers, Vigenere, transposition, XOR, or encoded text in CTF challenges that requires frequency analysis, Kasiski examination, or known-plaintext cryptanalysis.

yaklang/clickjacking

Clickjacking playbook. Use when testing whether target pages can be framed, whether X-Frame-Options or CSP frame-ancestors are properly configured, and whether UI redress attacks can trigger sensitive actions.

yaklang/cmdi-command-injection

Command injection playbook. Use when user input may reach shell commands, process execution, converters, import pipelines, or blind out-of-band command sinks.
