MAL-2026-15542 Malicious code in paper-password-input (npm)

package.json declares a dependency whose key equals the package's own name (paper-password-input) and whose value is a bare HTTPS URL, https://repo.securityctrl.com/paper-password-input, rather than a registry version range. On npm install, npm fetches whatever bytes are served at that URL with no version pin and no integrity check, and executes any lifecycle scripts inside the fetched tarball. The shipped index.js is an inert stub, so the manifest itself is the entire published surface — whoever controls repo.securityctrl.com can deliver arbitrary code to every installer, and the self-named dependency shape is consistent with a dependency-confusion lure targeting an internal package name.

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.
