Malicious package

@servicetitan/cp-uinpm

@servicetitan/cp-ui is a confirmed malicious npm package (MAL-2026-11847) that steals credentials and exfiltrates sensitive data (malicious versions 1.115.1, 1.115.2, 1.115.3…). Do not install it — remove it immediately and rotate any exposed credentials.

Immediate action
Remove the package, then rotate any secrets the build/runtime could reach.
npm uninstall @servicetitan/cp-ui

What this malware does

npm/@servicetitan/cp-ui 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.

package.json declares preinstall='node setup.mjs'. setup.mjs is identifier-obfuscated (obfuscator.io-style _0xXXXX names with wrapper-object string/call indirection) and, on npm install, downloads the Bun runtime from github.com/oven-sh/bun/releases/download/bun-v1.3.13/<platform>.zip, extracts and chmods the binary, then execFileSyncs it against a shipped 727KB single-line file math_init.js. math_init.js carries a '// @bun @bun-cjs' header, a large numeric constant array, and a string-array rotation decoder (function shifting/pushing an array of hex constants) — an opaque compiled Bun bundle. The package advertises itself as a React UI component library, which has no purpose-aligned reason to fetch a second language runtime or execute a compiled Bun bundle at install time. The combination — obfuscated preinstall script fetching an alternate runtime and using it to run an obfuscated in-tree payload automatically on npm install — is an install-time arbitrary-code-execution vector on the installer host, and the alien-runtime execution path bypasses Node/npm-focused scanners.

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.

Detection & response playbook

Credential / info stealer
  1. Find it

    Scan your lockfiles (package-lock.json, pnpm-lock.yaml, yarn.lock, requirements.txt, poetry.lock, etc.) and build artifacts for @servicetitan/cp-ui (7 malicious versions). O3 Security's supply-chain scanner checks every dependency against known-malicious package intelligence at install time and in CI, flagging @servicetitan/cp-ui across your stack and pipelines.

  2. If you installed it — respond

    @servicetitan/cp-ui is built to steal secrets, so assume every credential the build or runtime could read is compromised. Remove it from your project and lockfile, then rotate ALL exposed secrets — npm/registry tokens, cloud keys, CI/CD secrets, SSH keys, and any .env values — from a known-clean machine. Audit logs for unauthorized use of those credentials.

  3. Did it already run?

    If @servicetitan/cp-ui was ever installed, its post-install/runtime payload may have already executed. O3's L7 egress monitoring and runtime eBPF sensors detect the credential exfiltration or command-and-control callback after install and block the malicious outbound channel, so you catch and contain the actual compromise — not just the presence of the package.

  4. How O3 protects you

    O3 blocks @servicetitan/cp-ui before install through its supply-chain scanner, and if it has already run, detects and severs the exfiltration or C2 callback at runtime through L7 egress monitoring and eBPF.

Frequently asked questions

No. @servicetitan/cp-ui on npm has been identified as a malicious package (versions 1.115.1, 1.115.2, 1.115.3, 1.115.4, 1.115.5, 1.115.6, 1.115.7 flagged). It should be removed immediately — do not install or keep it in your dependency tree.
