My Heroku Platform API Key leaked! What should I do?

What is a Heroku Platform API Key and how it is used?

The Heroku Platform API Key is a unique token that grants access to the Heroku Platform API, allowing developers to programmatically manage and interact with their Heroku applications and resources.

Here are the main use cases for the Heroku Platform API Key:

  • Authentication: The Heroku Platform API Key is used to authenticate and authorize requests made to the Heroku Platform API. It serves as a secure way to ensure that only authorized users can access and interact with the platform.
  • Automated Tasks: Developers can use the API Key to automate various tasks such as deploying applications, scaling resources, and managing add-ons on the Heroku platform. This helps in streamlining workflows and improving efficiency.
  • Integration: The API Key allows developers to integrate Heroku services with other tools and platforms, enabling seamless communication and data exchange. This integration capability enhances the functionality and flexibility of the applications built on Heroku.

1. Code snippets to prevent Heroku Platform API Key hardcoding using environment variables

Using environment variables for storing sensitive information like API keys, such as the Heroku Platform API Key, is a secure practice for the following reasons:

  • Environment variables are not hard-coded in the codebase, reducing the risk of exposure in case of code leaks or public repositories.
  • They are stored outside of the codebase, making it harder for attackers to access them directly.
  • Environment variables are specific to the environment in which the code is running, providing an additional layer of security.
  • Heroku provides a secure way to manage environment variables through its dashboard, allowing for easy and safe storage of sensitive information.

3. Code snippet to prevent Heroku Platform API Key hardcoding using HashiCorp Vault

Using HashiCorp Vault for managing Heroku Platform API Keys is a great way to enhance security. Here are code snippets in five different programming languages for securely handling a Heroku Platform API 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 Heroku Platform API 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.

My Heroku Platform API Key leaked, what are the possible reasons?

There are several reasons why a Heroku Platform API Key might have been leaked:

  • Improper storage: Storing the API Key in plain text in code repositories or configuration files that are publicly accessible can lead to leaks.
  • Accidental exposure: Developers may inadvertently include the API Key in code snippets shared online or in documentation.
  • Weak access controls: Insufficient access controls on systems and services where the API Key is used can result in unauthorized access and potential leaks.
  • Phishing attacks: Social engineering tactics such as phishing emails or fake websites can trick individuals into disclosing their API Key.
  • Compromised systems: If the systems or devices where the API Key is stored are compromised, attackers may gain access to the key.

What are the risks of leaking a Heroku Platform API Key

When it comes to the Heroku Platform API Key, 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 a Heroku Platform API Key is leaked, unauthorized individuals may gain access to your Heroku account, potentially compromising your applications and data.
  • Data Breaches: A leaked API Key can lead to data breaches, exposing sensitive information stored on your Heroku platform to malicious actors.
  • Financial Loss: Hackers can exploit a leaked API Key to incur charges on your Heroku account, leading to financial losses for your organization.
  • Reputation Damage: A security breach resulting from a leaked API Key can tarnish your organization's reputation and erode trust among customers and partners.
  • Legal Consequences: Depending on the nature of the data exposed due to a leaked API Key, your organization may face legal repercussions and regulatory fines.

By understanding the risks associated with leaking a Heroku Platform API Key, developers can implement robust security measures to protect this sensitive information and safeguard their applications and data.

Heroku Platform API Key security best practices

  • Avoid embedding the secret directly in your code. Instead, use environment variables or secrets managers‍
  • Secure storage: store the Heroku Platform API 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 Heroku Platform API Key usage and improve the overall security of your Heroku Platform API Key implementations.

How to check if Heroku Platform API Key was used by malicious actors

  • Review Access Logs: Check the access logs of your Heroku Platform API Key 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 Heroku Platform API Key. This can give insights into any unauthorized use of your key.

Steps to revoke the Heroku Platform API Key

Generate a new Heroku Platform API Key:

  • Log into your Heroku Platform API 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 Heroku Platform API 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 Heroku Platform API 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.
