Malicious code in qlik-object-conversion (npm)
npm/qlik-object-conversion 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 scripts.preinstall = 'node setup.mjs'. setup.mjs downloads the Bun runtime from GitHub releases (oven-sh/bun), unzips it to a temporary directory, marks it executable, and invokes it against math_init.js — a 727KB Bun-compiled CJS bundle shipped alongside setup.mjs. math_init.js is heavily obfuscated (obfuscator.io-style rotated string/number array with a shuffle helper, mangled identifiers, '// @bun @bun-cjs' header) and is only executable under the downloaded Bun runtime, evading Node-based review. Both setup.mjs and math_init.js are present at the tarball root but not listed in the package.json 'files' manifest (which declares only /dist/conversion.js), indicating the payload files were added outside the normal publish surface. This is the alternate-runtime-dropper pattern: an object-conversion library has no legitimate need to fetch a JavaScript runtime and execute an opaque sibling bundle under it at install time.

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.
