Summary
Malicious code in @sapappgyver/appgyver-descriptors (npm)

The package declares an install lifecycle script that runs node index.js, which requires lib/core.js; the same module is the package main, so the payload also fires on any require() of the package. lib/core.js reads the installer's OS username, hostname, and current working-directory basename and encodes them as labels of a DNS subdomain under oob.sl4x0.xyz, then issues a dns.resolve4 lookup — leaking host and user identity to an author-controlled authoritative resolver. Sibling files lib/b02e30.js and lib/6ad264.js hide the module names (os, dns, process), the property names (userInfo, hostname, cwd, resolve4), and the destination host oob.sl4x0.xyz as arrays of char-code hex literals reconstructed with String.fromCharCode at runtime. The package name @sapappgyver/appgyver-descriptors is crafted to visually match SAP's legitimate @sap/appgyver-* scope; the repository github.com/slaxorg/nms-dashboard-js and author email research@sl4x0.xyz have no relation to SAP and align with the exfil domain.

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.
