Hardcoded Hazards: Detecting Secret Leaks in Source Code

- Posted in Other by - Permalink

Background: Organizations often invest significant resources in research and development (R&D), which can carry substantial risks—especially when sensitive information is inadvertently exposed in the source code. Hardcoded secrets, such as API keys, credentials, or tokens, can act as keys for attackers, granting unauthorized access to protected systems and sensitive data. This risk increases when version control systems are not properly managed and there is insufficient oversight of the codebase. In such cases, hardcoded secrets may accidentally be left in the public code or even reused across different projects, potentially leading to unintended exposure and exploitation.

Simulated Scnario: One day, an organization receives an email notifying them that their user database has been leaked. Following an investigation, a third-party security firm discovers that the database key was exposed in a publicly accessible repository.

Lesson learn: Let’s analyze the actions that the organization failed to take. By breaking down the issue into smaller parts, we can better understand what went wrong.

  1. Organization had not got secret scanning solution

Organization had not got secret scanning solution: To resolve this issue, we need to take a few simple steps. First, create a database that stores parts of the secrets or sensitive patterns currently present in your source code. Then, use a script to retrieve these values and scan over public repositories on the version control platform. If the script detects any matches, it should trigger a notification via your preferred communication channel.

Conclusion: Keeping secrets safe is a top priority for every organization, as they often serve as the key to the core of an organization's infrastructure. Rather than relying solely on policies and high-level compliance measures, it's essential to implement a 24/7 proactive monitoring service that can detect and respond to potential secret leaks in real time.
