DockerSpy: Search for images on Docker Hub, extract sensitive information
DockerSpy scans Docker Hub for images and retrieves sensitive information, including authentication secrets, private keys, and other confidential data.
“DockerSpy was created to address the growing concern of sensitive data leaks within Docker images, especially those publicly available on DockerHub. Many developers unknowingly publish images containing secrets such as API keys, credentials, or other sensitive information. DockerSpy automates the process of fetching these images and scanning them for secrets, offering a layer of security and compliance, reducing the risk of exposure,” Alisson Moretto, the creator of DockerSpy, told Help Net Security.
What sets DockerSpy apart is its automated integration with DockerHub, allowing it to seamlessly pull and analyze images without requiring manual uploads.
Its scanning engine is designed to identify a broad range of secret types, from hardcoded credentials to more complex patterns that may be hidden within code or environment variables. The tool also provides a detailed analysis and highlights the risks associated with any secrets found, making it easier to take immediate action.
Future plans and download
“In future versions, DockerSpy will focus on enhancing its detection capabilities by integrating machine learning models to better identify secrets even when they are obfuscated or disguised. We also plan to implement features for scanning private Docker repositories, offering more granular control for enterprise users. Additionally, DockerSpy will evolve to include integration with CI/CD pipelines so that scans can be run automatically during the build process, preventing images containing secrets from ever reaching production,” Moretto concluded.
DockerSpy is available for free on GitHub.
