yaklang/active-directory-kerberos-attacks

Active Directory Kerberos 攻擊劇本,適用於針對 AD 身份驗證的 AS-REP 烤製、Kerberoasting、金/銀/鑽石票據、委派濫用或傳遞票據攻擊。

active-directory-kerberos-attacks 是什麼?

該技能提供了一個專注於 Active Directory Kerberos 攻擊的劇本集合,適用於滲透測試人員和安全研究人員。它涵蓋了多種常見的 Kerberos 攻擊技術,包括 AS-REP 烤製(利用未啟用預身份驗證的帳戶)、Kerberoasting(提取服務帳戶的票據)、金票據(偽造域管理員票據)、銀票據(偽造服務票據)、鑽石票據(基於金票據的變種)、委派濫用(如基於資源的受限委派)以及傳遞票據攻擊。此技能基於 yaklang 語言開發,可在支持 yaklang 的平台上運行,例如 Yak Runner。它通過提供結構化的攻擊命令和參數,幫助用戶高效地執行和自動化這些攻擊,從而評估 AD 環境的安全性。

active-directory-kerberos-attacks 是做什麼的?

Active Directory Kerberos 攻擊劇本。當針對 AD 身份驗證進行 AS-REP 烤製、Kerberoasting、金票據/銀票據/鑽石票據、委派濫用或傳遞票據攻擊時使用。

簡介

此技能專為 Active Directory 環境中的 Kerberos 協議攻擊設計,提供了一套可重複使用的攻擊指令和策略。

攻擊技術

  • AS-REP 烤製:針對未啟用 Kerberos 預身份驗證的帳戶,請求 AS-REP 回應並離線破解密碼。
  • Kerberoasting:請求服務主體名稱 (SPN) 的服務票據,並離線破解服務帳戶密碼。
  • 金票據攻擊:偽造域管理員票據授予票據 (TGT),以獲得任意帳戶的域級訪問權限。
  • 銀票據攻擊:偽造服務票據,以訪問特定服務而不需要域控制器驗證。
  • 鑽石票據攻擊:基於金票據的變種,通過修改現有 TGT 的字段來偽造票據。
  • 委派濫用:利用 Kerberos 委派配置(如非約束委派、約束委派或基於資源的受限委派)來提升權限。
  • 傳遞票據攻擊:使用捕獲的 Kerberos 票據(如 TGT)進行身份驗證,無需密碼。

使用方法

在支援 yaklang 的環境中(如 Yak Runner),匯入此技能並根據目標情況選擇相應的攻擊模組。

注意事項

僅在授權的測試環境中使用此技能。未經授權使用可能違反法律法規。

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
