My Azure Subscription Key leaked! What should I do?
What is a Azure Subscription Key and how it is used?
An Azure Subscription Key is a unique identifier that allows access to resources within an Azure subscription. It is a crucial piece of information that should be securely managed and protected to prevent unauthorized access to Azure services.
Here are the main use cases for the Azure Subscription Key:
Authentication: The Azure Subscription Key is used as a unique identifier to authenticate and authorize access to Azure services and resources.
Resource Management: It is used to manage and control access to various Azure resources such as virtual machines, databases, storage accounts, etc.
Billing and Monitoring: The Azure Subscription Key is also used for billing purposes, tracking resource usage, and monitoring the performance of Azure services.

1. Code snippets to prevent Azure Subscription Key hardcoding using environment variables
Using environment variables for storing Azure Subscription Keys in your code can be a secure practice for the following reasons:
Separation of Concerns: Environment variables provide a way to separate sensitive information from your codebase, reducing the risk of accidental exposure.
Access Control: Access to environment variables can be restricted to authorized personnel, limiting the number of individuals who have direct access to the sensitive information.
Easy Configuration Management: Environment variables can be easily managed and updated without the need to modify the code, making it simpler to rotate keys and maintain security.
Secure Deployment: When deploying your application, environment variables are not included in the codebase, reducing the chances of exposing sensitive information during the deployment process.
2. Code snippet to prevent Azure Subscription Key hardcoding using AWS Secrets Manager
Using AWS Secrets Manager to manage Azure Subscription Keys is a secure way to handle sensitive data. Here are code snippets in five different programming languages that demonstrate how to retrieve the Azure Subscription Key from AWS Secrets Manager.

3. Code snippet to prevent Azure Subscription Key hardcoding using HashiCorp Vault
Using HashiCorp Vault for managing Azure Subscription Keys is a great way to enhance security. Here are code snippets in five different programming languages for securely handling a Azure Subscription Key using HashiCorp Vault.
Remember to replace the VAULT_ADDR and VAULT_TOKEN with your Vault server address and authentication token. The snippets assume that the Azure Subscription Key is stored under the api_key field within Vault. The specifics of the Vault path and field names should be adjusted to match your Vault setup.

How to generate a Azure Subscription Key?
To generate an Azure Subscription Key, developers can follow these steps:
Log in to the Azure portal using your credentials.
Go to the Azure portal dashboard and select the desired subscription.
Click on "Keys" or "Manage keys" in the subscription settings.
Generate a new key by clicking on the "Generate Key" or "Create Key" button.
Copy the generated key and securely store it for future use.

My Azure Subscription Key leaked, what are the possible reasons?
There are several reasons why an Azure Subscription Key might have been leaked:
Improper storage: If the key is stored in a plaintext file or hardcoded in the source code, it can easily be leaked.
Accidental exposure: Developers may inadvertently include the key in public repositories or share it in communication channels.
Insufficient access controls: Inadequate access controls on the key can lead to unauthorized access and potential leakage.
Compromised systems: If the systems where the key is stored are compromised, attackers can gain access to the key.
What are the risks of leaking a Azure Subscription Key
When it comes to Azure Subscription Keys, it is crucial for developers to understand the risks associated with leaking this sensitive information. Here are some key points to consider:
Unauthorized Access: If an Azure Subscription Key is leaked, unauthorized individuals may gain access to your Azure resources, leading to potential data breaches or unauthorized usage of your resources.
Financial Implications: Leaking an Azure Subscription Key can result in financial loss, as attackers may use the key to incur charges on your Azure account by spinning up resources or running expensive services.
Data Exposure: Leaking a Subscription Key can expose sensitive data stored in your Azure resources, putting your organization and its customers at risk of data theft or manipulation.
Reputation Damage: A security breach resulting from a leaked Azure Subscription Key can damage your organization's reputation and erode trust with customers and partners.
Therefore, it is essential for developers to follow best practices for secret management and detection to prevent the leakage of Azure Subscription Keys and mitigate the associated risks.

Azure Subscription Key security best practices
Avoid embedding the secret directly in your code. Instead, use environment variables or secrets managersā
Secure storage: store the Azure Subscription Key in a secure location, such as a password manager or a secrets management service.
Regular rotation: periodically rotate the API key to minimize the risk of long-term exposure.
Restrict permissions: apply the principle of least privilege by only granting the key the minimum necessary permissions.
Monitor usage: regularly check the usage logs for any unusual activity or unauthorized access attempts.
Implement access controls: limit the number of users who have access to the secret and enforce strong authentication measures.
Use a secrets manager: utilize secret management tools like CyberArk or AWS Secrets Manager for enhanced security.
By adhering to the best practices, you can significantly reduce the risk associated with Azure Subscription Key usage and improve the overall security of your Azure Subscription Key implementations.
How to check if Azure Subscription Key was used by malicious actors
Review Access Logs: Check the access logs of your Azure Subscription Key account for any unauthorized access or unusual activity. Pay particular attention to access from unfamiliar IP addresses (if you havenāt set up a specific allow list) or at odd hours.
Monitor Usage Patterns: Look for anomalies in the usage patterns, such as unexpected spikes in data access or transfer.
Check Active Connections and Operations: Review the list of active connections and recent operations on your database. Unusual or unauthorized operations might indicate malicious use.
Audit API Usage: If possible, audit the usage of your API key through any logging or monitoring services you have integrated with Azure Subscription Key. This can give insights into any unauthorized use of your key.

Steps to revoke the Azure Subscription Key
Generate a new Azure Subscription Key:
Log into your Azure Subscription Key account.
Navigate to the API section and generate a new API key.
Update Services with the new key:
Replace the compromised key with the new key in all your services that use this API key.
Ensure all your applications and services are updated with the new key before deactivating the old one.
Deactivate the old Azure Subscription Key:
Once the new key is in place and everything is functioning correctly, deactivate the old API key.
This can typically be done from the same section where you generated the new key.
Monitor after key rotation:
After deactivating the old key, monitor your systems closely to ensure that all services are running smoothly and that there are no unauthorized access attempts.

How to understand which services will stop working
Inventory of services: keep an inventory of all services and applications that utilize your Azure Subscription Key.
Communication and documentation: Ensure that your team is aware of which services are dependent on the key. Maintain documentation for quick reference.
Testing: before deactivating the old key, test your services with the new key in a staging environment. This helps in identifying any services that might face issues post rotation.
Fallback strategies: Have a fallback or emergency plan in case a critical service fails after the key rotation. This might include temporary measures or quick rollback procedures.
In summary, the remediation process involves identifying potential misuse, carefully rotating the key, and ensuring minimal disruption to services. Being proactive and having a well-documented process can greatly reduce the risks associated with a compromised API key.
