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.\n\n---\n_-= Per source details.

Both `setup.mjs` and `math_init.js` ship at the tarball root but are absent from the declared `files` manifest, which lists only `bin/`. The install-time payload filename (`math_init.js`) is unrelated to the package's stated purpose of delivering a prebuilt binary, and the shipped `bin/umadev.provenance.json` declares version 1.0.73 while the package itself is version 1.0.74, so the provenance does not cover the shipped binary. A prebuilt-binary package has no functional need to fetch a second language runtime and execute an obfuscated JS bundle at install time.\n\n## Source: ghsa-malware (f14a1d0851e79a4b1f36114b8e86e6772bbacc2435a146bb88a9434f3a59be8b)\nAny computer that has this package installed or running should be considered fully compromised.
