Summary
Malicious code in de-morgan (npm)
Details

package.json declares both a dependencies and devDependencies entry for de-morgan pointing at http://pack.nppacks.com/npm/de-morgan, a non-npm-registry host reached over plain HTTP with no version pin or integrity check. On npm install, npm fetches and installs whatever tarball is served from that URL into the dependency graph, executing any lifecycle scripts it contains. The visible index.js is a clone of babel-plugin-transform-define and carries a top-of-file comment stating This package use for Security Research Testing Purpose., but the shipped manifest wires in an attacker-controlled, mutable, plaintext delivery URL under a lookalike domain (nppacks.com), so the installed code path is whatever the remote host currently serves rather than the benign in-tree source.

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.
