Toyota suffered a data breach by accidentally exposing a secret key on GitHub (blog.gitguardian.com)

Article summary

Toyota suffered a data breach due to accidentally exposing a secret key on GitHub, which was accessible for nearly 5 years and potentially exposed data for over 290,000 customers. The key was hardcoded in a public repository, allowing access to a server that managed customer information. Toyota has since invalidated the key and begun outreach to affected customers. The incident highlights the importance of proper key management and security practices.

What commenters say

• Production keys should never be stored in source control, as it is a basic level of professional competency.
• The existence of bad practices does not mean efforts to mitigate them should be abandoned.
• Using external secrets managers or environment variables is a better approach than storing secrets in code.
• Even with Infrastructure as Code (IaC), secrets should be stored securely and not committed to source control.
• Some argue that encrypting secrets with another key not in source control can be a viable solution.
• Others believe that using an external service to provide secrets at runtime is a more secure approach.
• Code reviews and automated scanning tools can help catch and prevent secret leaks.
• Education and proper access control are crucial in preventing secrets from being mishandled.
