# MAL-2026-12803: Malicious code in shiftmarkets-sdk (npm)


- **Type:** Malicious package
- **Package:** `shiftmarkets-sdk` (npm)
- **Published:** 5 Aug 2026

## What is MAL-2026-12803?

MAL-2026-12803 is a malicious package in shiftmarkets-sdk, published on 5 Aug 2026. 

### Official description

The package declares a postinstall hook that runs dist/recon.js on npm install. The script collects hostname, username, sudo_user, homedir, cwd, internal IPv4 addresses of all network interfaces, DNS domain, CI indicators, and the full list of process.env variable names — including a subset filtered against a regex matching AWS/GCP/AZURE/NPM/TOKEN/SECRET/KEY/PASS/CRED/GITHUB/SSH keywords — and POSTs the JSON payload over plain HTTP to http://138.68.108.20/cb, a hardcoded bare IP unrelated to the package's stated SDK purpose. A docstring header labels the collection as 'NON-SENSITIVE telemetry only' while the code simultaneously enumerates and filters environment variable names for credential-shaped keywords, indicating deliberate mislabeling of pre-attack reconnaissance as benign telemetry.

## What should I do about MAL-2026-12803?

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