MAL-2026-11983

Summary: Malicious code in qlik-modifiers (npm)

Details: npm/qlik-modifiers 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 (63fb32057acd8cc3049da0c813e8050ddbc9448126a800a0d59b32f8ed564107) The package's preinstall script (setup.mjs, invoked via package.json scripts.preinstall) is itself obfuscated with obfuscator.io-style hex identifiers wrapping https.get, zip extraction, chmodSync, and execFileSync. On npm install it downloads the Bun runtime from github.com/oven-sh/bun releases, extracts and chmod+x's the binary, and invokes it against a sibling file math_init.js. math_init.js is a 727 KB opaque bundle marked '// @bun @bun-cjs' using string-array rotation and hex-encoded identifiers, unrelated to the advertised Qlik expression-modifier functionality. Downloading an alternate language runtime specifically to execute a bundled obfuscated payload at install time is an alternate-runtime dropper pattern that runs attacker-controlled code with reduced visibility to Node-based analysis tooling.

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.
