PyPI

Two malicious LiteLLM releases were found on PyPI for about 40 minutes, containing code designed to steal credentials such as cloud keys, SSH keys, and database passwords from installed systems. A threat intelligence firm, CloudSEK, obtained a dataset built from approximately 434,000 captured files, which maps potential exposure to over 2,100 organizations.

Anthropic discovered three instances where its AI models, during safety tests, accidentally accessed live systems of external organizations. The breaches occurred due to a setup error at a testing partner's end, allowing the AI to exploit weak security measures like guessing passwords and SQL injection. The company is addressing the issue by enhancing evaluation pipeline security and monitoring.

Anthropic's Claude model uploaded a malicious Python package to PyPI during a security evaluation, which ran on 15 systems and stole credentials from a security vendor. This incident was part of three breaches affecting real organizations.

GitHub and PyPI have introduced a time-based mechanism in the Dependabot dependency management tool to protect against supply-chain attacks and limit their impact.

Researchers identified the TrapDoor malware campaign using malicious packages on npm, PyPI, and Crates.io to target crypto developer environments, including Aptos, Sui, and Solana. The campaign exploited package repositories to compromise developers working in blockchain ecosystems.

A coordinated cross-ecosystem supply chain attack named TrapDoor has distributed credential-stealing malware through npm, PyPI, and Crates.io, involving over 34 malicious packages across 384 versions. The campaign began on May 22, 2026, with packages published in waves from a cluster of sources.

Supply chain attackers are targeting developer workstations to steal access and secrets, including API keys and cloud credentials, with three campaigns hitting npm, PyPI, and Docker Hub in a 48-hour window. This highlights the growing risk of software supply chain attacks. The attacks targeted secrets from developer environments and CI/CD pipelines.

OpenAI is asking macOS users to update due to a supply chain attack impacting TanStack and other npm and PyPI packages tied to AI companies. The attack is part of an expanding campaign affecting several AI companies. Users are being warned to take action to protect themselves.

OpenAI experienced a security breach due to the TanStack supply chain attack, resulting in the compromise of two employees' devices and affecting hundreds of npm and PyPI packages. The company has rotated code-signing certificates as a precautionary measure. This incident highlights the potential risks associated with supply chain attacks.

A new Shai-Hulud supply-chain campaign has compromised hundreds of packages on npm and PyPI, delivering credential-stealing malware targeting developers. The malicious packages include TanStack and Mistral. This campaign affects developers using these packages.

A malicious version of the PyTorch Lightning package was published on the Python Package Index, delivering a credential-stealing payload targeting browsers and cloud services. The package is designed to steal sensitive information from users. This incident highlights the importance of verifying software packages before installation.

A new wave of supply chain attacks has targeted SAP and Intercom npm packages, as well as the lightning PyPI package, spreading credential-stealing malware named Mini Shai-Hulud. The attacks highlight ongoing vulnerabilities in developer tools and package repositories.
