AI Agents Install Unowned Packages via Poisoned llms.txt Files

ATLAS OWASP CRITICAL Active exploitation · Immediate action required ▲ 9.2 Ars Technica Security

Researchers discovered that over 120 corporate websites contained misconfigured llms.txt files referencing unregistered package names, which AI coding agents including Claude, Codex, and Hermes automatically executed as trusted installation instructions. By registering a handful of the unclaimed package names and hosting beacon payloads, researchers received phone-home responses from dozens of companies including Fortune 500 firms within hours, confirming real-world agent-driven supply chain compromise. The attack exploits the implicit trust AI agents place in vendor documentation files, with at least one site found directing visitors to live malware.

Miasma Worm Compromises 73 Microsoft NPM Packages for AI Agents

Miasma Worm Compromises 73 Microsoft NPM Packages for AI Agents

ATLAS OWASP CRITICAL Active exploitation · Immediate action required ▲ 8.5 Ars Technica Security

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.

node-ipc Supply Chain Backdoor Steals Cloud and AI Credentials

node-ipc Supply Chain Backdoor Steals Cloud and AI Credentials

ATLAS OWASP CRITICAL Active exploitation · Immediate action required ▲ 7.2 The Hacker News

Three versions of the widely-used node-ipc npm package were found to contain obfuscated stealer/backdoor payloads published by an unauthorised maintainer account. The malware harvests 90 categories of developer secrets — including Claude AI and Kiro IDE configurations, AWS, Azure, and GCP credentials — and exfiltrates them via HTTPS and DNS tunnelling to an attacker-controlled domain. The compromise is notable for bypassing npm lifecycle hooks entirely and, in one version, targeting a specific developer via pre-computed SHA-256 fingerprinting.

Axios npm Library Compromised in Supply Chain Attack

Axios npm Library Compromised in Supply Chain Attack

ATLAS OWASP HIGH Significant risk · Prioritise patching ▲ 7.2 The Hacker News

A North Korean threat group (UNC1069) compromised the popular npm Axios library via a supply chain attack, injecting a backdoor (WAVESHAPER.V2) into two poisoned versions that were inadvertently downloaded by OpenAI's macOS app-signing GitHub Actions workflow. Although OpenAI found no evidence of certificate exfiltration or user data compromise, the incident exposed the signing credentials for ChatGPT Desktop, Codex, Codex CLI, and Atlas, prompting certificate revocation and mandatory app updates by May 8, 2026. The attack highlights the acute risk of software supply chain compromises against AI product delivery pipelines.
