Attackers pushed the malicious payload to the source repository and cut releases through GitHub Actions, so the poisoned versions reached npm with a valid, signed provenance attestation (provenance attests build integrity, not source integrity). Delivery is through the npm install lifecycle: the trojanized package.json adds a preinstall hook (`\"preinstall\": \"node setup.mjs\"`) that runs before any project code on a bare `npm install`, while the normal compiled output is left intact so the package still works after install. setup.mjs downloads a standalone Bun runtime and uses it to run a second stage (shipped as Math_Symbol.js, a heavily obfuscated ~728 KB Bun bundle, referenced at runtime as math_init.js). The stealer harvests credentials from cloud instance metadata (AWS IMDS at 169.254.169.254, ECS at 169.254.170.2, GCP, Azure), AWS/GCP/Azure keys, HashiCorp Vault tokens, Kubernetes service-account tokens, GitHub Actions OIDC and org/repo secrets, and npm tokens, with a TruffleHog-style regex sweep for further secrets and private keys. Using the stolen npm identity (including npm OIDC trusted publishing) it enumerates and republishes further packages the token can reach — which, for a maintainer controlling both keyv and cacheable, gave the worm a large blast radius. Stolen findings are exfiltrated to attacker-created GitHub repositories (descriptions reading \"Shai-Hulud: Here We Go Again\") and to destinations resolved over DNS, and autostart hooks are planted in the repository's .claude/ and .vscode/ configuration to run the loader when a developer or AI coding agent opens a clone. Treat any environment that installed this version (with install scripts enabled) as fully compromised and rotate every reachable credential. Part of the August 2026 npm worm that poisoned 400+ packages across many organizations.\n\n---\n_-= Per source details.

The advertised package purpose (an in-memory cache library) does not require a Bun runtime, the payload file is not referenced from dist/exports, and its contents are unreadable to Node-based inspection because they only execute under the Bun runtime fetched at install time. The alternate-runtime dropper pattern executes attacker-controlled code on every installer's machine during `npm install`.\n\n## Source: ghsa-malware (92314afe4c3865622168c2b31ff12571d4820fac8092147803caba6b228335bc)\nAny computer that has this package installed or running should be considered fully compromised.
