Threats Tagged 'cacheable'

A sophisticated supply-chain attack campaign named Shai-Hulud has compromised over 400 npm packages across 1700+ versions, beginning with keyv and cacheable libraries. The malware operates as a self-propagating worm that collects credentials from local filesystems, CI/CD environments, cloud platforms, Kubernetes clusters, and HashiCorp Vault. It exfiltrates stolen data through dynamic HTTPS endpoints or public GitHub repositories, then uses compromised npm tokens to publish infected versions of all writable packages. The campaign also injects execution hooks into GitHub repositories via VS Code and Claude configuration files, harvests GitHub Actions secrets through injected workflows, and includes a targeted attack against npm trusted publishing flows. Command and control infrastructure leverages Ethereum smart contracts and GitHub commit messages for resilience.

An active supply chain attack has compromised the keyv and cacheable npm packages, affecting tens of millions of weekly downloads. The attack began on August 4, 2026, when the maintainer account Jaredwray was compromised, enabling attackers to publish malicious code across multiple packages. The malware deploys through a preinstall hook that downloads a Bun runtime and executes obfuscated payloads designed to harvest cloud credentials from AWS, GCP, Azure, HashiCorp Vault, Kubernetes, GitHub Actions, and npm tokens. The threat exhibits worm-like behavior by using stolen npm tokens to republish trojanized versions of additional packages beyond the original namespaces. Stolen credentials are exfiltrated to attacker-controlled GitHub repositories via DNS-resolved destinations, with persistence mechanisms planted in developer environments through .claude and .vscode hooks.

Multiple npm packages in the keyv/cacheable ecosystem were compromised after attackers gained control of a GitHub maintainer account. Beginning at 9:00 UTC on August 4, 2026, the attacker introduced IDE persistence mechanisms and published malicious versions that propagated to over 400 distinct packages. The payload is a descendant of the 'Mini' Shai-Hulud malware family, sharing similarities with TeamPCP and antv campaigns. It targets sensitive data including cloud credentials, infrastructure secrets, developer credentials, AI configuration files, and cryptocurrency wallets. The malware uniquely retrieves command-and-control domains from an Ethereum smart contract rather than embedding them, allowing infrastructure updates without modifying the payload. Data is exfiltrated through GitHub repositories created under compromised identities. The campaign demonstrates sophisticated supply chain attack techniques targeting developer environments and CI/CD pipelines.
