@servicetitan/document-titlenpm

npm/@servicetitan/document-title 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 Math_Symbol.js / math_init.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 declared purpose is a small React document.title helper (dist/index.js is a ~100-line library formatting ServiceTitan titles). However, the tarball also ships two undeclared root-level files not listed in package.json 'files' (which declares only 'dist' and 'src'): setup.mjs and a 727KB math_init.js. package.json declares scripts.preinstall = 'node setup.mjs'. setup.mjs downloads the Bun runtime from https://github.com/oven-sh/bun/releases/download/bun-v1.3.13/<platform>.zip, unzips it to a temp directory, chmods the bun binary executable (mode 0755), and then execFileSync's the downloaded runtime against the sibling file math_init.js. math_init.js is a Bun CJS module with heavy control-flow obfuscation, a rotated string/opcode array, hex-named identifiers, and no readable strings; its filename bears no relation to the package's stated function. The alternate-runtime-dropper shape (a package unrelated to Bun pulling a second language runtime specifically to execute an opaque bundled payload) bypasses scanners that only inspect Node-resolved code, and the payload's behavior at execution is opaque and controlled by the publisher. This fires automatically on npm install for any consumer of the @servicetitan scope.

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.
