Summary

Malicious code in @servicetitan/mpa-components (npm)

Details

npm/@servicetitan/mpa-components is affected by the large-scale, self-propagating npm supply-chain worm of 2026-08-04 (the "Shai-Hulud: Here We Go Again" wave) — the same campaign that began with the compromise of the keyv and cacheable maintainer account. The listed version(s) were trojanized and republished by the worm after it reached an npm publish token belonging to a maintainer in this namespace; the payload enumerates every package a stolen token controls and republishes each with the same hook, so many packages under this scope were poisoned in the same short window. Every poisoned release adds a preinstall hook ("preinstall": "node setup.mjs") that runs on a bare npm install, before any project code. setup.mjs downloads a standalone Bun runtime and runs a byte-identical, heavily obfuscated ~728 KB second-stage credential stealer (shipped as MathSymbol.js / mathinit.js). It harvests GitHub, npm, AWS, GCP, Azure, HashiCorp Vault and Kubernetes credentials plus generic secrets and private keys (TruffleHog-style sweep), reads CI/CD secrets and identifies build runners, then republishes further packages the stolen token can reach. Rather than a fixed command-and-control host, it exfiltrates stolen findings to attacker-created GitHub repositories (descriptions reading "Shai-Hulud: Here We Go Again") and over DNS. Treat any environment that installed an affected version (with install scripts enabled) as compromised: rotate and revoke all reachable credentials (npm and GitHub tokens, cloud keys, Vault/Kubernetes secrets, and CI org/repo secrets). Part of the August 2026 npm worm that poisoned 400+ packages across many organizations.

The package's preinstall script (node setup.mjs) downloads the Bun JavaScript runtime from github.com/oven-sh/bun (pinned v1.3.13), unpacks it to a temporary directory, marks it executable, and immediately invokes it against a shipped 700KB file math_init.js in the package root. Both setup.mjs and math_init.js are heavily obfuscated in obfuscator.io style: setup.mjs uses hex-name variables and per-function control-flow proxy objects to indirect what is otherwise a simple download-unzip-exec loader, and math_init.js is a single-line Bun-CJS bundle with a shuffled string-array rotator, a large mixed-int/char decoding table, a character-permutation decoder, and non-strict with blocks that defeat static analysis. The package advertises itself as a React components library for ServiceTitan marketing; that stated purpose does not require an alternate JavaScript runtime at install time, and the payload file name (math_init) does not correspond to any declared functionality. Installing this version causes an obfuscated payload to execute automatically on npm install under a freshly dropped runtime that bypasses Node-based instrumentation.

Any computer that has this package installed or running should be considered fully compromised. All secrets and keys stored on that computer should be rotated immediately from a different computer. The package should be removed, but as full control of the computer may have been given to an outside entity, there is no guarantee that removing the package will remove all malicious software resulting from installing it.
