Miasma Worm Compromises 73 Microsoft NPM Packages for AI Agents

ATLAS OWASP CRITICAL ▲ 8.5 Ars Technica Security Jun 09, 2026

Seventy-three Microsoft-hosted open source packages were compromised with the Miasma credential-stealing worm, which activates specifically when developers open packages inside AI coding agents. The malware, attributed to threat actor TeamPCP, exploits legitimate OIDC token workflows and SLSA provenance attestation to bypass supply-chain integrity checks and spread laterally across cloud infrastructure. This marks the second such compromise of an official Microsoft repository in as many months, indicating a sustained campaign targeting developer toolchains and the AI-assisted development pipeline.

TanStack Supply Chain Attack Exposes OpenAI Keys

ATLAS OWASP HIGH ▲ 8.5 The Hacker News May 15, 2026

A supply chain attack targeting TanStack via the Mini Shai-Hulud malware compromised two OpenAI employee devices, exposing internal source code repositories and code-signing certificates for macOS, iOS, and Windows apps. While no user data or production systems were breached, OpenAI was forced to revoke and reissue signing certificates, requiring macOS users to update ChatGPT Desktop, Codex, and Atlas apps before June 12, 2026. The incident marks OpenAI's second certificate rotation in two months and is part of a broader campaign by threat actor TeamPCP targeting major AI and open-source ecosystems.

TeamPCP Steals Mistral AI Source Code via Supply Chain

ATLAS OWASP HIGH ▲ 8.5 BleepingComputer May 15, 2026

The TeamPCP threat group has compromised Mistral AI's codebase management system via the Shai-Hulud software supply chain attack, stealing approximately 5GB of internal repositories covering training, fine-tuning, benchmarking, and inference pipelines. The hackers are demanding $25,000 for nearly 450 repositories or threatening to leak them publicly within a week. Mistral AI confirmed the breach but stated that core repositories, hosted services, managed user data, and research environments were not affected.

CVE-2026-45321: Supply Chain Worm Targets Mistral AI

ATLAS OWASP CRITICAL ▲ 9.2 The Hacker News May 13, 2026

The TeamPCP threat actor has executed a broad supply chain campaign dubbed Mini Shai-Hulud, injecting credential-stealing malware into npm and PyPI packages from major AI and developer tooling ecosystems including Mistral AI, Guardrails AI, and TanStack. The malware profiles execution environments, exfiltrates cloud, CI, and AI tool credentials, and establishes persistence inside Claude Code and VS Code IDEs. The TanStack compromise alone affected 42 packages and 84 versions, exploiting a chained GitHub Actions attack to inject malicious payloads without stealing npm tokens directly.

TeamPCP Supply Chain Campaign Poisons xinference PyPI

ATLAS OWASP HIGH ▲ 6.5 SANS Internet Storm Center Apr 28, 2026

The TeamPCP supply chain campaign resumed after a 26-day pause with three concurrent compromises targeting Checkmarx KICS (Docker Hub), xinference (a popular AI inference PyPI package), and a cascading compromise of Bitwarden CLI via poisoned CI/CD dependencies. The xinference poisoning is directly AI-security relevant as it targets a widely used LLM/ML model serving framework, while the broader campaign demonstrates sophisticated supply chain attack methodologies that increasingly intersect with AI tooling. The CanisterSprawl npm worm adds credential-harvesting infrastructure that could further compromise AI development pipelines.
