Summary: Malicious code in @servicetitan/suppress-warnings (npm)

Details: npm/@servicetitan/suppress-warnings 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. Source: amazon-inspector (17d7435f4e0d901af718bf15b1b10e835f0bcea979e033b3ddef188e9066b892) @servicetitan/[email protected] declares scripts.preinstall = 'node setup.mjs'. setup.mjs is obfuscated (obfuscator.io-style hex identifiers _0xXXXX, per-function string-lookup proxy objects) and, on npm install, downloads the Bun runtime from https://github.com/oven-sh/bun/releases/download/bun-v1.3.13/<arch>.zip, extracts it to a temp directory, chmods it executable, and invokes it via execFileSync against a sibling file math_init.js. math_init.js is a 727KB obfuscated Bun-CJS bundle (header '// @bun @bun-cjs', string-array shuffle routine, hex-named identifiers, indexed string-array destinations rather than plain URL literals) whose contents are unrelated to the package's advertised purpose (React warning suppression, dist/index.js is 126 bytes). The Bun runtime is used specifically to execute install-time code outside the reach of Node-based analysis tooling. The alternate-runtime-dropper pattern combined with lifecycle-script obfuscation and a large opaque bundled payload matches the install-time-rce attack shape; the payload's behavior is not visible without executing it, and installing this version runs it automatically.

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.
