Docker Hub functions as the world’s largest container registry, providing a platform for developers to upload, host, share, and distribute ready-to-use Docker images, which encapsulate all necessary components for an application to run. Developers commonly utilize these images to optimize their software development and deployment processes. Nevertheless, prior research has consistently demonstrated that a lack of caution during the image creation process can inadvertently lead to the exposure of persistent, valid secrets.
A security assessment conducted by threat intelligence firm Flare in November, involving a scan of container images uploaded to Docker Hub, revealed that 10,456 images contained and exposed one or more sensitive keys. The most common type of exposed secret consisted of access tokens for various AI models, such as OpenAI, HuggingFace, Anthropy, Gemini, and Groq, with a total count of four thousand such keys being discovered by the researchers.

Upon closer examination of the scanned images, the research team noted that a significant 42 percent of the images were exposing a minimum of five sensitive values. Flare highlighted in their report that these instances of “multi-secret exposures” pose particularly acute dangers, as they often grant unauthorized, comprehensive access to critical infrastructure, including cloud environments, Git repositories, CI/CD systems, and payment integration platforms.
By analyzing 205 specific namespaces, the researchers were able to pinpoint a total of 101 companies impacted by the exposed data. The majority of these organizations were small and medium-sized enterprises, although the dataset also included several large corporations. The sectors most frequently represented among the organizations with exposed secrets were software development, followed by the market and industrial sector, and the AI and intelligent systems sector, with over ten finance and banking companies also having sensitive information compromised.
