My Salesforce Refresh Tokens leaked! What should I do?

What is a Salesforce Refresh Tokens and how it is used?

Salesforce Refresh Tokens are long-lived tokens that can be used to obtain new access tokens without the need for the user to re-enter their credentials. They are typically used in OAuth 2.0 authentication flows to maintain user sessions and access to resources.

When it comes to Salesforce Refresh Tokens, developers should understand the following main use cases:

  • Allowing long-term access to Salesforce APIs without requiring the user to re-enter credentials frequently.
  • Enabling the application to obtain new access tokens without requiring the user to log in again, thus improving user experience.
  • Helping in maintaining the security of the application by reducing the risk of storing sensitive user credentials.

1. Code snippets to prevent Salesforce Refresh Tokens hardcoding using environment variables

Using environment variables for Salesforce Refresh Tokens in your code is a secure practice because:

  • Environment variables are not hard-coded in the codebase, reducing the risk of exposure through version control systems or code repositories.
  • Environment variables are stored outside of the codebase and are not accessible to unauthorized users who may have access to the code.
  • Environment variables can be managed securely by the system administrator, allowing for easy rotation and revocation of tokens without changing the code.

How to generate a Salesforce Refresh Tokens?

To generate Salesforce Refresh Tokens, developers can follow these steps:

  • 1. Obtain a client ID and client secret by registering a new connected app in the Salesforce Developer Console.
  • 2. Use the client ID and client secret to make a POST request to the Salesforce token endpoint with the necessary parameters (grant_type, client_id, client_secret, username, password).
  • 3. If the request is successful, Salesforce will respond with an access token, refresh token, and other relevant information.
  • 4. Store the refresh token securely as it will be used to obtain new access tokens when the current one expires.

My Salesforce Refresh Tokens leaked, what are the possible reasons?

There are several reasons why Salesforce Refresh Tokens might have been leaked:

  • Weak or compromised credentials: If a developer's Salesforce login credentials are weak or compromised, it can lead to unauthorized access and leakage of refresh tokens.
  • Insecure storage: Storing refresh tokens in plaintext or insecure locations such as code repositories or configuration files can expose them to potential leaks.
  • Improper access controls: Inadequate access controls or misconfigured permissions can allow unauthorized users to access and misuse refresh tokens.
  • Insufficient encryption: If refresh tokens are not properly encrypted or protected, they can be intercepted and stolen by malicious actors.
  • Phishing attacks: Developers falling victim to phishing attacks can inadvertently disclose their Salesforce credentials, leading to the leakage of refresh tokens.

What are the risks of leaking a Salesforce Refresh Tokens

As a security trainer, it is important to educate developers on the risks associated with leaking Salesforce Refresh Tokens. Refresh Tokens are a critical component in maintaining the security of Salesforce integrations, as they are used to obtain new access tokens without requiring the user to re-enter their credentials. However, if a Refresh Token is leaked, it can lead to serious security vulnerabilities and potential data breaches.

  • Unauthorized Access: If a Refresh Token falls into the wrong hands, malicious actors can use it to impersonate a legitimate user and gain unauthorized access to sensitive data stored in Salesforce.
  • Data Breaches: Leaking a Refresh Token can potentially lead to a data breach, resulting in the exposure of confidential information, financial data, or intellectual property.
  • Reputation Damage: A security incident stemming from a leaked Refresh Token can severely damage an organization's reputation and erode customer trust.
  • Compliance Violations: Mishandling Refresh Tokens can lead to compliance violations with regulations such as GDPR, HIPAA, or PCI DSS, resulting in legal repercussions and financial penalties.

It is crucial for developers to implement strong security practices when handling Salesforce Refresh Tokens, including encrypting them at rest, restricting access to authorized personnel only, and regularly rotating them to mitigate the risk of exposure. By raising awareness about the risks associated with leaking Refresh Tokens, developers can better protect their applications and safeguard sensitive data.

Salesforce Refresh Tokens security best practices

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

How to check if Salesforce Refresh Tokens was used by malicious actors

  • Review Access Logs: Check the access logs of your Salesforce Refresh Tokens 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 Salesforce Refresh Tokens. This can give insights into any unauthorized use of your key.

Steps to revoke the Salesforce Refresh Tokens

Generate a new Salesforce Refresh Tokens:

  • Log into your Salesforce Refresh Tokens 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 Salesforce Refresh Tokens:

  • 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 Salesforce Refresh Tokens.
  • 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.
