# MAL-2026-12427: Malicious code in remote_session_elements (npm)

## What is MAL-2026-12427?

MAL-2026-12427 is a malicious package in remote_session_elements, published on 5 Aug 2026. 

### Official description

Package version 9999.0.0 is published with placeholder metadata ("Shared utility helpers.", no author) — the canonical shape of a dependency-confusion squat designed to override an internal package of the same name during resolution. On `npm install`, the `scripts.preinstall` hook runs `node callback.js`, which reads `os.hostname()`, `os.userInfo().username`, the current working directory, the configured npm registry, and CI-provided repository identifiers (e.g. `process.env.GITHUB_REPOSITORY`) and sends them via HTTP GET to `http://75.119.137.232:31337/depconfuse?pkg=...`, a hardcoded bare-IP endpoint over cleartext HTTP. This provides an external operator with the internal package name, host identity, and originating CI repository slug of every environment where the squat is installed — reconnaissance for further dependency-confusion attacks against the victim's internal package namespace.

## What should I do about MAL-2026-12427?

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