GitGuardian reported 62 active leaked PyPI tokens, affecting 125 packages on the platform. The tokens were primarily found on GitHub, with 19,586 occurrences identified, narrowing down to 3,714 unique tokens after filtering. The tokens, which are bearer tokens with specific restrictions, were mostly leaked in 2024. GitHub's scanning integration with PyPI, established in 2021, aims to revoke exposed tokens automatically. However, a significant number of tokens remain valid, indicating gaps in GitHub's scanning capabilities. The potential impact includes around 13,000 monthly downloads across affected packages. GitHub's recent enhancements to secret scanning may improve future detection and revocation of leaked tokens.

Key Points: • 62 active leaked PyPI tokens identified, affecting 125 packages. • Most tokens were leaked on GitHub, with a significant number remaining valid. • GitHub's integration with PyPI aims to revoke exposed tokens automatically.
