A new wave of the Mini Shai-Hulud/Miasma/Hades supply chain attack campaign has compromised 23 npm packages across the LeoPlatform and RStreams ecosystems, plus the Verana Blockchain Go module. The attack uses binding.gyp install-time execution (Phantom Gyp pattern) to trigger multi-stage obfuscated JavaScript loaders that decrypt AES-GCM payloads, stage execution through Bun to evade Node.js security hooks, and steal developer/CI/CD credentials including npm, GitHub, cloud, and AI-agent tokens. The campaign also poisons GitHub Actions workflows and plants persistence hooks in AI coding assistant configurations, creating delayed execution surfaces that survive package remediation.

The Shai-Hulud software supply chain campaign has significantly evolved, expanding from npm to PyPI and shifting from maintainer compromise to CI/CD abuse. Recent waves demonstrate advanced techniques including OIDC token scraping to bypass SLSA provenance, IDE configuration file weaponization, and prompt injection designed to evade LLM-based security scanners.

The third wave of the Shai-Hulud supply chain worm, dubbed Miasma, targets the npm ecosystem by utilizing weaponized binding.gyp files to bypass lifecycle script monitoring. It establishes deep persistence within AI assistant and IDE configuration directories, evades detection through dormancy and EDR checks, and abuses valid Sigstore attestations to masquerade as legitimate packages.

A coordinated supply chain attack compromised 19 PyPI packages, utilizing malicious .pth files to achieve execution at Python startup. The loader downloads the Bun runtime to execute an obfuscated JavaScript stealer targeting developer secrets, cloud credentials, and CI/CD tokens, exfiltrating data via GitHub repositories and Actions.

A highly coordinated supply chain attack compromised 56 npm packages across 286 versions by abusing the binding.gyp native build configuration to silently execute malicious code during installation. The multi-stage, heavily encrypted payload targets CI/CD environments to harvest cloud credentials, propagates via stolen OIDC tokens, and establishes persistence with a destructive dead man's switch.

At Pwn2Own Berlin 2026, security researchers demonstrated 47 unique zero-day vulnerabilities across AI platforms and traditional enterprise software. Notable exploits included root-level code execution in AI agents via trust boundary failures, a SYSTEM-level RCE in Microsoft Exchange, a pre-authentication RCE in SharePoint, and a cross-tenant guest-to-host escape in VMware ESXi.

A suspected TeamPCP-linked supply chain attack compromised multiple SAP CAP and Cloud MTA npm packages by injecting malicious preinstall scripts. The attack leverages a downloaded Bun runtime to execute an obfuscated payload that harvests extensive credentials from developer machines and CI/CD pipelines, exfiltrating data via attacker-controlled GitHub repositories and establishing persistence through VSCode and Claude AI configurations.

Attackers are increasingly targeting CI/CD pipelines to harvest secrets and pivot to production environments using techniques like workflow modification and privileged trigger exploitation. Elastic has released an open-source tool, cicd-abuse-detector, which leverages regex-based signal extraction and LLM analysis to detect suspicious pipeline changes during the pull request phase.

Elastic's InfoSec team details a scalable architecture for monitoring AI coding assistants, specifically Claude Code and Cowork, using OpenTelemetry and Elasticsearch. The solution provides security teams with critical visibility into AI agent activities, including shell command execution, file access, and internal API interactions, enabling advanced threat detection, incident response, and EDR correlation.
