Supply Chain Attack Using Ethereum Smart Contracts to Distribute Multi-Platform Malware

Description

A sophisticated supply chain attack has been discovered targeting the NPM ecosystem. The malicious package 'jest-fet-mock' impersonates popular testing utilities and uses Ethereum smart contracts for command-and-control operations. This cross-platform malware affects Windows, Linux, and macOS, executing during package installation via preinstall scripts. It performs info-stealing actions and establishes persistence across infected systems. The attack leverages blockchain technology for resilient C2 infrastructure, making it difficult to detect and take down. This approach represents a notable shift in supply chain attack methodologies, combining blockchain with traditional attack vectors. The campaign specifically targets development environments and CI/CD pipelines, posing a significant threat to software supply chains.
