On August 4, 2026, ChainDrop, a self-propagating worm variant of Mini Shai-Hulud linked to TeamPCP, infiltrated the npm ecosystem through a compromised maintainer account of the keyv ecosystem. The attacker injected malicious code into GitHub repositories, weaponizing legitimate CI/CD pipelines to publish poisoned packages with valid SLSA Build Level 3 provenance attestations, making them indistinguishable from clean releases. ChainDrop spread to over 400 packages within four hours by stealing npm tokens and republishing infected versions. The worm employs Ethereum smart contracts for C2 infrastructure, enabling domain rotation without modifying deployed malware. It features destructive capabilities, wiping victim home directories upon token revocation, and achieves persistence through IDE and AI-agent configuration files. The payload harvests credentials from npm, GitHub, AWS, Azure, GCP, Kubernetes, HashiCorp Vault, and other services, exfiltrating data via GitHub repositories and EtherHiding techniques.

On August 4, 2026, a sophisticated supply chain attack compromised the keyv npm package maintainer, deploying CHAINDROP, a self-propagating worm that automatically backdoors packages using stolen npm credentials. Over 400 npm packages were infected, affecting more than 1.3 billion monthly downloads. The worm executes via preinstall hooks, deploys across Linux, macOS, and Windows platforms, and harvests credentials from over 300 patterns targeting AI tooling, cloud providers, GitHub tokens, and npm credentials. CHAINDROP uses Ethereum smart contracts for C2 resolution and propagates by publishing trojanized versions of packages the compromised maintainer can access. The payload is heavily obfuscated and contains Dune-themed references consistent with previous Shai-Hulud campaigns.
