# MAL-2026-6463: Malicious code in abu-common-components (npm)

## What is MAL-2026-6463?

MAL-2026-6463 is a malicious package in abu-common-components, published on 25 Jun 2026. 

### Official description

package.json declares preinstall and postinstall hooks that invoke curl against a hardcoded bare-IP HTTP endpoint (http://64.227.183.144/depconf/abu-common-components/), sending the installer's username ($(whoami)), hostname ($(hostname)), current working directory ($PWD) and timestamp as query parameters. This fires automatically on `npm install` with no caller consent, leaks internal host and build-path identifiers in cleartext, and points at a non-publisher bare IP. The package itself is hollow — index.js is a one-line placeholder — and is published at the inflated version 99.99.1 by an anonymous author, the canonical shape of a dependency-confusion probe designed to be resolved ahead of a private internal package of the same name. The combination of the /depconf/<pkgname>/ URL path, the inflated version, and the placeholder body confirms reconnaissance intent: any organization with a private `abu-common-components` package will leak its existence and internal host fingerprints to the attacker on a single `npm install`.

## What should I do about MAL-2026-6463?

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