Leaked credentials have become a significant issue in recent years, particularly within the Python community. This article highlights the alarming number of secrets added to PyPI, the official third-party package management system for Python [2], and the potential consequences of these leaks.


According to security researchers, over the past year alone [3], more than 1,000 unique secrets have been added to PyPI. These secrets include various credentials such as AWS Keys, Redis credentials [1] [2] [4], Google API keys [2], and database credentials [2]. Valid credentials are a primary vector for cyber-attacks [2], making these leaks a serious concern.

A recent analysis of Python code committed to PyPI packages has revealed a critical threat to organizations. Security firm GitGuardian and researcher Tom Forbes discovered close to 4,000 unique secrets in nearly 3,000 PyPI packages [3], with over 760 of them being valid [3]. These secrets include credentials for platforms such as AWS [3], Azure AD [3], GitHub [3], and Dropbox. Validating leaked secrets is crucial in incident investigations [3], and GitGuardian notes that they were able to validate less than 800 credentials [3].

The number of secrets leaked in PyPI packages has been steadily increasing [1] [3] [4], with over 1,000 secrets added in the past year alone [1] [3]. Most of these leaked secrets were found in py files [3], but credentials were also discovered in configuration/documentation files and test folders [3]. Accidental leakage is the main cause of secrets exposure in PyPI, highlighting the need for Python developers to avoid using unencrypted credentials and to scan their code for secrets before releasing it [3].


The Python Package Index plays a crucial role in the software supply chain [2], running an estimated 90% of production code. Therefore, it is essential to raise awareness and implement preventive measures to protect against unauthorized access and social engineering tactics. Recommendations include implementing automated secrets scanning and leveraging cloud secrets managers to enhance security. The impact of leaked credentials can be severe, and it is crucial for organizations and developers to take proactive steps to mitigate these risks in the future.
