On July 14, 2026, a coordinated supply chain attack compromised the @asyncapi npm organization, affecting five package versions across four packages. The attack originated from a GitHub Actions workflow vulnerability that exposed privileged credentials, enabling unauthorized code injection. Unlike typical postinstall attacks, this campaign executes at module import time, bypassing common npm install --ignore-scripts protections. The malicious code spawned hidden processes that fetched a second-stage payload from IPFS, deploying the Miasma modular runtime with command-and-control capabilities, persistence mechanisms, and credential harvesting features. The payload included disabled modules for supply-chain propagation, AI-tool poisoning, and sandbox evasion. All compromised packages were published through legitimate GitHub OIDC workflows with valid provenance signatures, masking the malicious activity within trusted release processes.
