No npm Token Required: Inside the AsyncAPI Supply Chain Attack
Executive Summary Upwind identified a critical supply chain compromise across five npm packages in the @asyncapi scope, published on July 14, 2026 via two separate branch compromises in two GitHub repositories. The attacker never touched an npm token. They abused each project's own CI pipeline through GitHub Actions OIDC to publish the malicious packages. The…
Upwind Now Detects Novel Supply Chain Attacks in Real Time
Software supply chain attacks are no longer rare events that make headlines once a quarter. In 2026, significant attacks are landing every few days, and the pace is accelerating. AI-assisted code generation is lowering the barrier for attackers to craft sophisticated, obfuscated payloads and inject them into trusted open source packages at scale. The window…
Newly Discovered durabletask Malware Targeted Kubernetes, Cloud Secrets, and CI/CD Infrastructure
Executive Summary Upwind identified a critical supply chain compromise involving durabletask==1.4.1, 1.4.2, and 1.4.3, three consecutive malicious releases of Microsoft's Azure Durable Task Python SDK published to PyPI. The malicious release contains a lightweight dropper embedded directly into durabletask/init.py. On import, the package downloads and executes a remote payload named rope.pyz from attacker-controlled infrastructure. The…
The New Face of Supply Chain Attacks: npm Malware Built for CI/CD and Cloud Compromise
Executive Summary Upwind is tracking an active software supply chain campaign impacting multiple npm packages commonly used across developer tooling, frontend frameworks, CI/CD pipelines, and cloud-native application environments. We identified malicious payloads designed specifically to target CI/CD systems, cloud identities, GitHub credentials, npm publishing workflows, developer machines, and AI developer tooling. The campaign includes install-time…
The Supply Chain Strikes Again: Credential-Stealing Malware Hidden in node-ipc
Executive Summary On May 14, 2026, malicious versions of the widely used node-ipc npm package were published through a legitimate maintainer account, introducing a sophisticated credential-stealing payload into a package with approximately 3.35 million monthly downloads. The malicious payload was hidden inside the CommonJS bundle (node-ipc.cjs) and silently executed whenever applications loaded the package through…
Shai-Hulud: Here We Go Again – Dissecting a Supply Chain Worm Across the TanStack Ecosystem
Executive Summary A new wave of the Mini Shai-Hulud campaign compromised dozens of official @tanstack/* npm packages by abusing CI/CD publishing workflows and trusted npm release mechanisms. Unlike traditional dependency malware focused only on downstream execution, this operation behaves as a self-propagating supply chain worm designed to continuously spread across repositories, developer environments, and CI/CD…
A Mini Shai-Hulud Has Appeared: Dissecting a Multi-Vector npm Supply Chain Worm
TL;DR: [email protected] is malicious. It uses Bun runtime smuggling for EDR evasion, scrapes GitHub Actions runner memory for secrets, harvests credentials from every major cloud provider and secrets management system, exfiltrates through RSA-4096 encrypted channels, injects a secret-dumping GitHub Actions workflow disguised as Dependabot, poisons every branch of compromised repos with files disguised as Claude…
