MAL-2026-4826

Summary: Malicious code in wm-mapper (npm)

Details: Source: amazon-inspector (380f281f71ec04bc9867a9b12d46852936494de6d2be3df55b1422bde2f5f01d) [email protected] is an empty stub (index.js is 35 bytes exporting `{}`, no description, no author) published at an artificially high version (99.9.1) consistent with dependency-confusion attacks against an internal package of the same name. Its package.json declares its sole runtime dependency as a direct HTTPS tarball URL — `"ltidisafe": "https://ltidi.storage.googleapis.com/depenconf/ltidisafe-2.7.5.tgz"` — bypassing the npm registry entirely. The path segment literally contains `depenconf` (dependency confusion). On `npm install`, npm fetches that tarball from an anonymous Google Cloud Storage bucket and executes any lifecycle scripts (preinstall/install/postinstall) it declares. The bucket contents are not vetted by the registry, are mutable server-side after publication, and the bucket owner has no apparent affiliation with the host package. The host package's only effect on installers is to drag arbitrary, swappable, attacker-controlled code into the install tree.

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.
