npm/@servicetitan/intl 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.
-= Per source details. Do not edit below this line.=-
The package's preinstall hook (scripts.preinstall = "node setup.mjs") downloads the Bun JavaScript runtime from https://github.com/oven-sh/bun/releases/download/bun-v<version>/<target>.zip, extracts bun/bun.exe into a temp directory, chmods it executable, and invokes it against a sibling file mathinit.js at install time. setup.mjs performs platform and libc detection (probes ldd for musl and reads /etc/os-release for 'Alpine') to select among bun-linux-x64-baseline, bun-linux-x64-musl-baseline, darwin x64/arm64, and win32 x64/arm64 variants, maximizing coverage across developer machines, CI runners, and Alpine containers. mathinit.js is a ~727KB single-line bundle marked // @bun @bun-cjs with hex-obfuscated identifiers (_0xNNNN-style), a WV8StW string-array rotator, and a large numeric index array n7gIxM — the standard obfuscator.io shape, opaque to human inspection. An internationalization library has no legitimate reason to fetch a second JavaScript runtime and execute an obfuscated bundle at install time; the alternate-runtime dropper pattern moves execution outside the normal Node inspection surface, and the obfuscation conceals whatever the payload does on the installer's host.
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.
