My Sourcegraph Access Token leaked! What should I do?

What is a Sourcegraph Access Token and how it is used?

An Access Token in Sourcegraph is a unique string of characters that grants access to specific resources and services within the Sourcegraph platform. It is used for authentication and authorization purposes to ensure secure access to sensitive information.

Sourcegraph Access Token is used for:

  • Authentication: Developers use the access token to authenticate their identity when accessing Sourcegraph services and resources.
  • Authorization: The token is used to grant specific permissions and access levels to developers, allowing them to interact with Sourcegraph resources based on their roles and responsibilities.
  • API Integration: Developers can use the access token to integrate Sourcegraph functionality into their applications and workflows, enabling seamless communication and data exchange between systems.

1. Code snippets to prevent Sourcegraph Access Token hardcoding using environment variables

Using environment variables for storing sensitive information like Sourcegraph Access Tokens is a secure practice because:

  • Environment variables are not hardcoded in the codebase, reducing the risk of accidental exposure through version control systems or code sharing platforms.
  • Environment variables are stored outside of the codebase, making it harder for unauthorized users to access them directly.
  • Environment variables can be easily managed and rotated without having to modify the code, enhancing security by minimizing the exposure window of sensitive information.
  • Environment variables are typically encrypted or obfuscated by the operating system, providing an additional layer of protection against unauthorized access.

My Sourcegraph Access Token leaked, what are the possible reasons?

There are several reasons why a Sourcegraph Access Token might have been leaked:

  • 1. Insecure storage: Storing the access token in a plaintext file or hardcoding it directly in the code can lead to accidental exposure.
  • 2. Sharing credentials: Sharing access tokens with unauthorized users or including them in public repositories can result in leaks.
  • 3. Weak authentication: Using weak passwords or easily guessable tokens can make it easier for attackers to access and misuse the token.
  • 4. Lack of encryption: Transmitting the access token over unsecured channels or using insecure protocols can expose it to interception.
  • 5. Phishing attacks: Falling victim to phishing scams or social engineering tactics can lead to the disclosure of access tokens.

What are the risks of leaking a Sourcegraph Access Token

As a security trainer, it is crucial to educate developers on the risks associated with leaking a Sourcegraph Access Token. Sourcegraph Access Tokens are sensitive pieces of information that grant access to various resources and services within the Sourcegraph platform. If a Sourcegraph Access Token is leaked, it can lead to serious security vulnerabilities and potential breaches. Here are some specific risks of leaking a Sourcegraph Access Token:

  • Unauthorized access: An attacker who gains access to a Sourcegraph Access Token can use it to impersonate a legitimate user and gain unauthorized access to sensitive data and resources.
  • Data exposure: Leaking a Sourcegraph Access Token can expose confidential information stored within Sourcegraph, putting the organization's data at risk of being compromised.
  • Malicious activities: Attackers can use a leaked Sourcegraph Access Token to perform malicious activities such as injecting malicious code, deleting important data, or disrupting services.
  • Reputation damage: A security incident resulting from a leaked Sourcegraph Access Token can damage the organization's reputation and erode trust with customers and partners.

It is essential for developers to understand the importance of safeguarding Sourcegraph Access Tokens and following best practices for secret management to prevent leaks and mitigate security risks.

Sourcegraph Access Token security best practices

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

How to check if Sourcegraph Access Token was used by malicious actors

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

Steps to revoke the Sourcegraph Access Token

Generate a new Sourcegraph Access Token:

  • Log into your Sourcegraph 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 Sourcegraph 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 Sourcegraph 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.
