My Yelp API key leaked! What should I do?

What is a Yelp API key and how it is used?

An API key for the Yelp API is a unique identifier that allows developers to access and interact with Yelp's services and data, such as business information and reviews.

Here are the main use cases for the Yelp API key:

  • Accessing Yelp's business data: Developers use the Yelp API key to retrieve information about businesses, such as their name, address, ratings, and reviews.
  • Implementing search functionality: The Yelp API key allows developers to integrate search functionality into their applications, enabling users to search for businesses based on various criteria.
  • Displaying business details: Developers can use the Yelp API key to display detailed information about a specific business, including photos, contact information, and operating hours.

1. Code snippets to prevent Yelp API key hardcoding using environment variables

Using environment variables to store sensitive information like API keys, such as the Yelp API key, is a secure practice for several reasons:

  • Environment variables are stored outside of the codebase, reducing the risk of accidental exposure through version control systems or code sharing platforms.
  • They can be easily managed and updated without requiring changes to the code itself, making it simpler to rotate keys regularly for improved security.
  • Environment variables are typically encrypted and protected by the operating system, adding an extra layer of security compared to hardcoding keys in the code.
  • By using environment variables, developers can adhere to the principle of least privilege, ensuring that only authorized individuals have access to sensitive information.

3. Code snippet to prevent Yelp API key hardcoding using HashiCorp Vault

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

How to generate a Yelp API key?

To generate a Yelp API key, developers need to follow these steps:

  1. Sign up for a Yelp account or log in to an existing account.
  2. Go to the Yelp Fusion API page on the Yelp Developer website.
  3. Click on the "Create App" button to create a new app.
  4. Fill out the required information for the app, such as the name, description, and website URL.
  5. Agree to the Yelp API Terms of Use and click on the "Submit" button.
  6. Once the app is created, the API key will be generated and displayed on the app dashboard.
  7. Copy the API key and use it in your application to make requests to the Yelp API.

My Yelp API key leaked, what are the possible reasons?

There are several reasons why a Yelp API key might have been leaked, including:

  • Poor secret management practices, such as storing the API key in a public repository or hardcoding it in the codebase.
  • Accidental exposure through logging or error messages that include the API key.
  • Compromised systems or unauthorized access to sensitive information.
  • Lack of proper access controls and monitoring mechanisms to detect unauthorized access to the API key.

What are the risks of leaking a Yelp API key

When developers leak a Yelp API key, they expose themselves to various risks that can have serious consequences. It is important for developers to understand the specific risks associated with leaking a Yelp API key:

  • Unauthorized Access: Leaking a Yelp API key can allow unauthorized individuals or malicious actors to access sensitive information or perform actions on behalf of the developer.
  • Data Breaches: Exposing a Yelp API key can lead to potential data breaches, where sensitive data from users or the developer's application may be compromised.
  • Financial Loss: Unauthorized access to a Yelp API key can result in financial loss, as attackers may use the key to make unauthorized transactions or incur charges.
  • Reputation Damage: A data breach or unauthorized access due to a leaked Yelp API key can damage the developer's reputation and erode trust with users and partners.
  • Legal Consequences: Depending on the nature of the leaked information and any resulting damages, developers may face legal consequences for negligence or failure to protect sensitive data.

Yelp API key security best practices

  • Avoid embedding the secret directly in your code. Instead, use environment variables or secrets managersā€
  • Secure storage: store the Yelp 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 Yelp API key usage and improve the overall security of your Yelp API key implementations.

Yelp API key leak remediation: what to do

What to do if you expose a secret: How to stay calm and respond to an incident [cheat sheet included]

How to check if Yelp API key was used by malicious actors

  • Review Access Logs: Check the access logs of your Yelp API key account for any unauthorized access or unusual activity. Pay particular attention to access from unfamiliar IP addresses (if you havenā€™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 Yelp API key. This can give insights into any unauthorized use of your key.

Steps to revoke the Yelp API key

Generate a new Yelp API key:

  • Log into your Yelp 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 Yelp 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 Yelp 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.
