My Azure DevOps Personal Access Token leaked! What should I do?

What is a Azure DevOps Personal Access Token and how it is used?

An Azure DevOps Personal Access Token (PAT) is a secure authentication method that allows an individual to access resources within Azure DevOps without the need to enter their username and password.

Here are the main use cases for Azure DevOps Personal Access Tokens:

  • Authentication: Personal Access Tokens are used for authenticating with Azure DevOps services, allowing developers to access and interact with resources securely.
  • API Access: Developers can use Personal Access Tokens to authenticate their applications when making API calls to Azure DevOps, enabling automation and integration with various tools and services.
  • Permission Management: Personal Access Tokens can be scoped with specific permissions, allowing developers to control and limit the access levels of their applications or scripts within Azure DevOps.

1. Code snippets to prevent Azure DevOps Personal Access Token hardcoding using environment variables

Using environment variables for Azure DevOps Personal Access Tokens in code is a secure practice because:

  • Environment variables are not hard-coded in the codebase, reducing the risk of exposure.
  • Environment variables are stored outside of the code repository, adding an extra layer of security.
  • Access to environment variables can be restricted based on user permissions, limiting who can view or modify them.
  • Environment variables can be easily rotated or revoked without changing the code itself, improving security maintenance.

3. Code snippet to prevent Azure DevOps Personal Access Token hardcoding using HashiCorp Vault

Using HashiCorp Vault for managing Azure DevOps Personal Access Tokens is a great way to enhance security. Here are code snippets in five different programming languages for securely handling a Azure DevOps Personal Access Token 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 DevOps Personal Access Token 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 DevOps Personal Access Token?

To generate a Personal Access Token (PAT) in Azure DevOps, follow these steps:

  1. Sign in to your Azure DevOps account.
  2. Click on your profile icon in the top right corner and select "Security".
  3. Under the "Personal access tokens" section, click on "New Token".
  4. Provide a name for your token and select the organization where you want to use it.
  5. Choose the desired expiration date for the token.
  6. Select the scopes or permissions that the token should have.
  7. Click on "Create" to generate the token.
  8. Make sure to copy the token and store it securely, as you won't be able to see it again.

Once you have generated your PAT, you can use it for authentication when accessing Azure DevOps services via REST API or other tools that require authentication.

My Azure DevOps Personal Access Token leaked, what are the possible reasons?

There are several reasons why an Azure DevOps Personal Access Token might have been leaked:

  • Storing the token in a public repository or codebase
  • Accidentally sharing the token in a public forum or chat
  • Using weak or easily guessable token values
  • Granting excessive permissions to the token
  • Logging the token in plaintext in application logs
  • Compromised developer machine or environment

What are the risks of leaking a Azure DevOps Personal Access Token

When it comes to Azure DevOps Personal Access Tokens (PATs), it is crucial for developers to understand the risks associated with leaking such sensitive information. PATs are used to authenticate to Azure DevOps services, and if they fall into the wrong hands, they can lead to serious security breaches. Here are some of the risks of leaking an Azure DevOps PAT:

  • Unauthorized access: An attacker who gains access to a PAT can potentially perform actions on behalf of the compromised user, such as accessing sensitive data, modifying code, or even deleting repositories.
  • Data breaches: Leaking a PAT can result in unauthorized access to confidential data stored in Azure DevOps, leading to data breaches and potential legal consequences.
  • Compromised infrastructure: If an attacker obtains a PAT with sufficient permissions, they could potentially compromise the entire infrastructure hosted on Azure DevOps, causing widespread damage.
  • Reputation damage: A security breach resulting from a leaked PAT can tarnish the reputation of the organization, leading to loss of trust from customers and partners.

It is essential for developers to follow best practices for managing and securing their Azure DevOps PATs to prevent these risks and protect the integrity of their projects and data.

Azure DevOps Personal Access Token security best practices

  • Avoid embedding the secret directly in your code. Instead, use environment variables or secrets managers‍
  • Secure storage: store the Azure DevOps Personal Access Token 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 DevOps Personal Access Token usage and improve the overall security of your Azure DevOps Personal Access Token implementations.

How to check if Azure DevOps Personal Access Token was used by malicious actors

  • Review Access Logs: Check the access logs of your Azure DevOps Personal Access Token account for any unauthorized access or unusual activity. Pay particular attention to access from unfamiliar IP addresses (if you haven’t 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 DevOps Personal Access Token. This can give insights into any unauthorized use of your key.

Steps to revoke the Azure DevOps Personal Access Token

Generate a new Azure DevOps Personal Access Token:

  • Log into your Azure DevOps Personal Access Token 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 DevOps Personal Access Token:

  • 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 DevOps Personal Access Token.
  • 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.
